Description
[0001] This application claims the benefit of U.S. Provisional
Application No. 60/581,851, filed Jun. 22, 2004, the entire content
of which is herein incorporated by reference.
FIELD OF THE INVENTION
[0002] This invention is in the field of plant molecular biology.
More specifically, this invention pertains to isolated
polynucleotides comprising nucleic acid fragments encoding
galactinol synthase homologs in plants and seeds wherein all or
part of such isolated polynucleotides can be used to down-regulate
expression of endogenous genes encoding galactinol synthase.
BACKGROUND OF THE INVENTION
[0003] Raffinose saccharides are a group of D-galactose-containing
oligosaccharide derivatives of sucrose that are widely distributed
in plants. Raffinose saccharides are characterized by the general
formula:
[O-.beta.-D-galactopyranosyl-(1.fwdarw.6).sub.n-.alpha.-glucopyranosyl-(1-
.fwdarw.2)-.beta.-D-fructofuranoside where n=0 through n=4 are
known respectively as sucrose, raffinose, stachyose, verbascose,
and ajugose. A set of galactosyltransferases is involved in the
biosynthesis of raffinose saccharides. Galactinol synthase (EC
2.4.1.123) catalyzes the synthesis of galactinol
(O-.alpha.-D-gal-actopyranosyl-[1.fwdarw.1]-L-myo-inositol) from
UDP-D-Gal and myo-inositol. Raffinose and stachyose are then
synthesized by addition of Gal units from galactinol to sucrose and
raffinose, respectively. These reversible reactions are mediated by
raffinose synthase (EC 2.4.1.82) and stachyose synthase (EC
2.4.1.67). Transfer of a further Gal residue from galactinol to
stachyose gives verbascose.
[0004] Extensive botanical surveys of the occurrence of raffinose
saccharides have been reported in the scientific literature [see
Dey (1985) in Biochemistry of Storage Carbohydrates in Green
Plants, P. M. Dey and R. A. Dixon, Eds. Academic Press, London, pp.
53-129]. Raffinose saccharides are thought to be second only to
sucrose with respect to abundance among the nonstructural
carbohydrates in the plant kingdom. In fact, raffinose saccharides
may be ubiquitous, at least among higher plants. Raffinose
saccharides accumulate in significant quantities in the edible
portion of many economically significant crop species. Examples
include soybean (Glycine max L. Merrill), sugar beet (Beta
vulgaris), cotton (Gossypium hirsutum L.), canola (Brassica sp.)
and all of the major edible leguminous crops including beans
(Phaseolus sp.), chick pea (Cicer arietinum), cowpea (Vigna
unguiculata), mung bean (Vigna radiata), peas (Pisum sativum),
lentil (Lens culinaris) and lupine (Lupinus sp.).
[0005] Although abundant in many species, raffinose saccharides are
an obstacle to the efficient utilization of some economically
important crop species. Raffinose saccharides are not digested
directly by animals, primarily because alpha-galactosidase is not
present in the intestinal mucosa [Gitzelmann et al. (1965)
Pediatrics 36:231-236; Rutloff et al. (1967) Nahrung 11:39-46].
However, microflora in the lower gut are readily able to ferment
the raffinose saccharides resulting in an acidification of the gut
and production of carbon dioxide, methane and hydrogen gases
[Murphy et al. (1972) J. Agr. Food. Chem. 20:813-817; Cristofaro et
al. (1974) in Sugars in Nutrition, H. L. Sipple and K. W. McNutt,
Eds. Academic Press, New York, Chap. 20, 313-335; Reddy et al.
(1980) J. Food Science 45:1161-1164]. The resulting flatulence can
severely limit the use of leguminous plants in animal, particularly
human, diets. It is unfortunate that the presence of raffinose
saccharides restricts the use of legumes in human diets because
many of these species are otherwise excellent sources of protein
and soluble fiber. Varieties of edible beans free of raffinose
saccharides would be more valuable for human diets and would more
fully use the desirable nutritional qualities of edible leguminous
plants.
[0006] The biosynthesis of raffinose saccharides has been well
characterized [see Dey (1985) in Biochemistry of Storage
Carbohydrates in Green Plants, P. M. Dey and R. A. Dixon, Eds.
Academic Press, London, pp. 53-129]. The committed reaction of
raffinose saccharide biosynthesis involves the synthesis of
galactinol from UDP-galactose and myo-inositol. The enzyme that
catalyzes this reaction is galactinol synthase (inositol
1-alpha-galactosyltransferase; EC 2.4.1.123). Synthesis of
raffinose and higher homologues in the raffinose saccharide family
from sucrose is thought to be catalyzed by distinct
galactosyltransferases (for example, raffinose synthase and
stachyose synthase). Studies in many species suggest that
galactinol synthase is the key enzyme controlling the flux of
reduced carbon into the biosynthesis of raffinose saccharides
[Handley et al. (1983) J. Amer. Soc. Hort. Sci. 108:600-605;
Saravitz, et al. (1987) Plant Physiol. 83:185-189].
[0007] Related galactinol synthase genes already known in the art
include sequences disclosed in WO 01/77306 and in U.S. Pat. No.
5,648,210, Kerr et al. (the contents of which are hereby
incorporated by reference), and Sprenger and Keller (2000) Plant J
21:249-258. Presumably related sequences are also disclosed in WO
98/50553.
[0008] There is a great deal of interest in identifying the genes
that encode proteins involved in raffinose saccharides in plants.
Specifically, the galactinol synthase gene may be used to alter
galactinol synthesis and modulate the level of raffinose
saccharides in plant cells. Accordingly, the availability of
nucleic acid sequences encoding all or a portion of a galactinol
synthase would facilitate studies to better understand raffinose
synthesis in plants, and provide genetic tools to alter raffinose
saccharide synthesis to enhance the nutritional qualities of many
edible leguminous plants.

nucleotide sequence characters and the three letter codes for amino
acids as defined in conformity with the IUPAC-IUBMB standards
described in Nucleic Acids Res. 13:3021-3030 (1985) and in the
Biochemical J. 219 (No. 2):345-373 (1984) which are herein
incorporated by reference.
DETAILED DESCRIPTION OF THE INVENTION
[0080] In the context of this disclosure, a number of terms shall
be utilized. The terms "polynucleotide," "polynucleotide sequence,"
"nucleic acid sequence," and "nucleic acid fragment"/"isolated
nucleic acid fragment" are used interchangeably herein. These terms
encompass nucleotide sequences and the like. A polynucleotide may
be a polymer of RNA or DNA that is single- or double-stranded, that
optionally contains synthetic, non-natural or altered nucleotide
bases. A polynucleotide in the form of a polymer of DNA may be
comprised of one or more segments of cDNA, genomic DNA, synthetic
DNA, or mixtures thereof. An isolated polynucleotide of the present
invention may include at least 30 contiguous nucleotides,
preferably at least 40 contiguous nucleotides, most preferably at
least 60 contiguous nucleotides derived from SEQ ID NOs:1 or 3 or
5, or the complement of such sequences.
[0081] The term "isolated" refers to materials, such as nucleic
acid molecules and/or proteins, which are substantially free or
otherwise removed from components that normally accompany or
interact with the materials in a naturally occurring environment.
Isolated polynucleotides may be purified from a host cell in which
they naturally occur. Conventional nucleic acid purification
methods known to skilled artisans may be used to obtain isolated
polynucleotides. The term also embraces recombinant polynucleotides
and chemically synthesized polynucleotides.
[0082] The term "recombinant" means, for example, that a nucleic
acid sequence is made by an artificial combination of two otherwise
separated segments of sequence, e.g., by chemical synthesis or by
the manipulation of isolated nucleic acids by genetic engineering
techniques.
[0083] A "recombinant DNA construct" comprises any of the isolated
polynucleotides of the present invention operably linked to at
least one regulatory sequence.
[0084] As used herein, "substantially similar" refers to nucleic
acid fragments wherein changes in one or more nucleotide bases
results in substitution of one or more amino acids, but do not
affect the functional properties of the polypeptide encoded by the
nucleotide sequence. "Substantially similar" also refers to nucleic
acid fragments wherein changes in one or more nucleotide bases does
not affect the ability of the nucleic acid fragment to mediate
alteration of gene expression by gene silencing through for example
antisense or co-suppression technology. "Substantially similar"
also refers to modifications of the nucleic acid fragments of the
instant invention such as deletion or insertion of one or more
nucleotides that do not substantially affect the functional
properties of the resulting transcript vis-a-vis the ability to
mediate gene silencing or alteration of the functional properties
of the resulting protein molecule. It is therefore understood that
the invention encompasses more than the specific exemplary
nucleotide or amino acid sequences and includes functional
equivalents thereof. The terms "substantially similar" and
"corresponding substantially" are used interchangeably herein.
[0085] "Sequence identity" or "identity" in the context of nucleic
acid or polypeptide sequences refers to the nucleic acid bases or
amino acid residues in the two sequences that are the same when
aligned for maximum correspondence over a specified comparison
window.
[0086] Thus, "Percentage of sequence identity" refers to the valued
determined by comparing two optimally aligned sequences over a
comparison window, wherein the portion of the polynucleotide
sequence in the comparison window may comprise additions or
deletions (i.e., gaps) as compared to the reference sequence (which
does not comprise additions or deletions) for optimal alignment of
the two sequences. The percentage is calculated by determining the
number of positions at which the identical nucleic acid base or
amino acid residue occurs in both sequences to yield the number of
matched positions, dividing the number of matched positions by the
total number of positions in the window of comparison and
multiplying the results by 100 to yield the percentage of sequence
identity. Useful examples of percent sequence identities include,
but are not limited to, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%,
90%, or 95%, or any integer percentage from 55% to 100%. These
identities can be determined using any of the programs described
herein.
[0087] The "Clustal V method of alignment" corresponds to the
alignment method labeled Clustal V (described by Higgins and Sharp
(1989) CABIOS. 5: 151-153) and found in the Megalign program of the
LASERGENE bioinformatics computing suite (DNASTAR Inc., Madison,
Wis.). The "default parameters" are the parameters preset by the
manufacturer of the program and for multiple alignments they
correspond to GAP PENALTY=10 and GAP LENGTH PENALTY=10, while for
pairwise alignments they are KTUPLE 1, GAP PENALTY=3, WINDOW=5 and
DIAGONALS SAVED=5. After alignment of the sequences, using the
Clustal V program, it is possible to obtain a "percent identity" by
viewing the "sequence distances" table in the same program.
[0088] Substantially similar nucleic acid fragments may be selected
by screening nucleic acid fragments representing subfragments or
modifications of the nucleic acid fragments of the instant
invention, wherein one or more nucleotides are substituted, deleted
and/or inserted, for their ability to affect the level of the
polypeptide encoded by the unmodified nucleic acid fragment in a
plant or plant cell. For example, a substantially similar nucleic
acid fragment representing at least 30 contiguous nucleotides,
preferably at least 40 contiguous nucleotides, most preferably at
least 60 contiguous nucleotides derived from the instant nucleic
acid fragment can be constructed and introduced into a plant or
plant cell. The level of the polypeptide encoded by the unmodified
nucleic acid fragment present in a plant or plant cell exposed to
the substantially similar nucleic fragment can then be compared to
the level of the polypeptide in a plant or plant cell that is not
exposed to the substantially similar nucleic acid fragment.
[0089] For example, it is well known in the art that antisense
suppression and co-suppression of gene expression may be
accomplished using nucleic acid fragments representing less than
the entire coding region of a gene, and by using nucleic acid
fragments that do not share 100% sequence identity with the gene to
be suppressed. Moreover, alterations in a nucleic acid fragment,
which result in the production of a chemically equivalent amino
acid at a given site, but do not affect the functional properties
of the encoded polypeptide, are well known in the art. Thus, a
codon for the amino acid alanine, a hydrophobic amino acid, may be
substituted by a codon encoding another less hydrophobic residue,
such as glycine, or a more hydrophobic residue, such as valine,
leucine, or isoleucine. Similarly, changes which result in
substitution of one negatively charged residue for another, such as
aspartic acid for glutamic acid, or one positively charged residue
for another, such as lysine for arginine, can also be expected to
produce a functionally equivalent product. Nucleotide changes which
result in alteration of the N-terminal and C-terminal portions of
the polypeptide molecule would also not be expected to alter the
activity of the polypeptide. Each of the proposed modifications is
well within the routine skill in the art, as is determination of
retention of biological activity of the encoded products.
Consequently, an isolated polynucleotide comprising a nucleotide
sequence of at least 30 (preferably at least 40, most preferably at
least 60) contiguous nucleotides derived from a nucleotide sequence
of SEQ ID NOs:1, 3 or 5 and the complement of such nucleotide
sequences may be used to affect the expression and/or function of a
galactinol synthase in a host cell. A method of using an isolated
polynucleotide to affect the level of expression of a
polynucleotide in a host cell (eukaryotic, such as plant or yeast,
prokaryotic such as bacterial) may comprise the steps of:
constructing an isolated polynucleotide of the present invention or
an isolated recombinant DNA construct of the present invention;
introducing the isolated polynucleotide or the isolated recombinant
DNA construct into a host cell; measuring the level of a
polypeptide or enzyme activity in the host cell containing the
isolated polynucleotide; and comparing the level of a polypeptide
or enzyme activity in the host cell containing the isolated
polynucleotide with the level of a polypeptide or enzyme activity
in a host cell that does not contain isolated polynucleotide.
[0090] Moreover, substantially similar nucleic acid fragments may
also be characterized by their ability to hybridize. Estimates of
such homology are provided by either DNA-DNA or DNA-RNA
hybridization under conditions of stringency as is well understood
by those skilled in the art (Hames and Higgins, Eds. (1985) Nucleic
Acid Hybridization, IRL Press, Oxford, U.K.). Stringency conditions
can be adjusted to screen for moderately similar fragments, such as
homologous sequences from distantly related organisms, to highly
similar fragments, such as genes that duplicate functional enzymes
from closely related organisms. Post-hybridization washes determine
stringency conditions. One set of preferred conditions uses a
series of washes starting with 6.times.SSC, 0.5% SDS at room
temperature for 15 min, then repeated with 2.times.SSC, 0.5% SDS at
45.degree. C. for 30 min, and then repeated twice with
0.2.times.SSC, 0.5% SDS at 50.degree. C. for 30 min. A more
preferred set of stringent conditions uses higher temperatures in
which the washes are identical to those above except for the
temperature of the final two 30 min washes in 0.2.times.SSC, 0.5%
SDS was increased to 60.degree. C. Another preferred set of highly
stringent conditions uses two final washes in 0.1.times.SSC, 0.1%
SDS at 65.degree. C.
[0091] Substantially similar nucleic acid fragments of the instant
invention may also be characterized by the percent identity of the
amino acid sequences that they encode to the amino acid sequences
disclosed herein, as determined by algorithms commonly employed by
those skilled in this art. Suitable nucleic acid fragments
(isolated polynucleotides of the present invention) encode
polypeptides that are at least about 85% identical to the amino
acid sequences reported herein. More preferred nucleic acid
fragments encode amino acid sequences that are at least about 90%
identical to the amino acid sequences reported herein. Most
preferred are nucleic acid fragments that encode amino acid
sequences that are at least about 95% identical to the amino acid
sequences reported herein. Suitable nucleic acid fragments not only
have the above identities but typically encode a polypeptide having
at least 50 amino acids, preferably at least 100 amino acids, more
preferably at least 150 amino acids, still more preferably at least
200 amino acids, and most preferably at least 250 amino acids.
[0092] It is well understood by one skilled in the art that many
levels of sequence identity are useful in identifying related
polypeptide sequences. Useful examples of percent identities are
50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, or 95%, or any integer
percentage from 55% to 100%. Sequence alignments and percent
identity calculations were performed using the Megalign program of
the LASERGENE bioinformatics computing suite (DNASTAR Inc.,
Madison, Wis.). Multiple alignment of the sequences was performed
using the Clustal method of alignment (Higgins and Sharp (1989)
CABIOS. 5:151-153) with the default parameters (GAP PENALTY=10, GAP
LENGTH PENALTY=10). Default parameters for pairwise alignments
using the Clustal method were KTUPLE 1, GAP PENALTY=3, WINDOW=5 and
DIAGONALS SAVED=5.
[0093] A "substantial portion" of an amino acid or nucleotide
sequence comprises an amino acid or a nucleotide sequence that is
sufficient to afford putative identification of the protein or gene
that the amino acid or nucleotide sequence comprises. Amino acid
and nucleotide sequences can be evaluated either manually by one
skilled in the art, or by using computer-based sequence comparison
and identification tools that employ algorithms such as BLAST
(Basic Local Alignment Search Tool; Altschul et al. (1993) J. Mol.
Biol. 215:403-410; see also the explanation of the BLAST algorithm
on the world wide web site for the National Center for
Biotechnology Information at the National Library of Medicine of
the National Institutes of Health). In general, a sequence of ten
or more contiguous amino acids or thirty or more contiguous
nucleotides is necessary in order to putatively identify a
polypeptide or nucleic acid sequence as homologous to a known
protein or gene. Moreover, with respect to nucleotide sequences,
gene-specific oligonucleotide probes comprising 30 or more
contiguous nucleotides may be used in sequence-dependent methods of
gene identification (e.g., Southern hybridization) and isolation
(e.g., in situ hybridization of bacterial colonies or bacteriophage
plaques). In addition, short oligonucleotides of 12 or more
nucleotides may be used as amplification primers in PCR in order to
obtain a particular nucleic acid fragment comprising the primers.
Accordingly, a "substantial portion" of a nucleotide sequence
comprises a nucleotide sequence that will afford specific
identification and/or isolation of a nucleic acid fragment
comprising the sequence. The instant specification teaches amino
acid and nucleotide sequences encoding polypeptides that comprise
one or more particular plant proteins. The skilled artisan, having
the benefit of the sequences as reported herein, may now use all or
a substantial portion of the disclosed sequences for purposes known
to those skilled in this art. Accordingly, the instant invention
comprises the complete sequences as reported in the accompanying
Sequence Listing, as well as substantial portions of those
sequences as defined above.
[0094] "Codon degeneracy" refers to divergence in the genetic code
permitting variation of the nucleotide sequence without effecting
the amino acid sequence of an encoded polypeptide. Accordingly, the
instant invention relates to any nucleic acid fragment comprising a
nucleotide sequence that encodes all or a substantial portion of
the amino acid sequences set forth herein. The skilled artisan is
well aware of the "codon-bias" exhibited by a specific host cell in
usage of nucleotide codons to specify a given amino acid.
Therefore, when synthesizing a nucleic acid fragment for improved
expression in a host cell, it is desirable to design the nucleic
acid fragment such that its frequency of codon usage approaches the
frequency of preferred codon usage of the host cell.
[0095] "Synthetic nucleic acid fragments" can be assembled from
oligonucleotide building blocks that are chemically synthesized
using procedures known to those skilled in the art. These building
blocks are ligated and annealed to form larger nucleic acid
fragments which may then be enzymatically assembled to construct
the entire desired nucleic acid fragment. "Chemically synthesized",
as related to a nucleic acid fragment, means that the component
nucleotides were assembled in vitro. Manual chemical synthesis of
nucleic acid fragments may be accomplished using well-established
procedures, or automated chemical synthesis can be performed using
one of a number of commercially available machines. Accordingly,
the nucleic acid fragments can be tailored for optimal gene
expression based on optimization of the nucleotide sequence to
reflect the codon bias of the host cell. The skilled artisan
appreciates the likelihood of successful gene expression if codon
usage is biased towards those codons favored by the host.
Determination of preferred codons can be based on a survey of genes
derived from the host cell where sequence information is
available.
[0096] "Gene" refers to a nucleic acid fragment that expresses a
specific protein, including regulatory sequences preceding (5'
non-coding sequences) and following (3' non-coding sequences) the
coding sequence. "Native gene" refers to a gene as found in nature
with its own regulatory sequences. "Recombinant DNA construct"
refers to any gene that is not a native gene, comprising regulatory
and coding sequences that are not found together in nature.
Accordingly, a recombinant DNA construct may comprise regulatory
sequences and coding sequences that are derived from different
sources, or regulatory sequences and coding sequences derived from
the same source, but arranged in a manner different than that found
in nature. "Endogenous gene" refers to a native gene in its natural
location in the genome of an organism. A "foreign-gene" refers to a
gene not normally found in the host organism, but that is
introduced into the host organism by gene transfer. Foreign genes
can comprise native genes inserted into a non-native organism,
recombinant DNA constructs, or recombinant DNA constructs. A
"transgene" is an isolated nucleic acid fragment or recombinant DNA
construct that has been introduced into the genome by a
transformation procedure.
[0097] "Coding sequence" refers to a nucleotide sequence that codes
for a specific amino acid sequence. "Regulatory sequences" refer to
nucleotide sequences located upstream (5' non-coding sequences),
within, or downstream (3' non-coding sequences) of a coding
sequence, and which influence the transcription, RNA processing or
stability, or translation of the associated coding sequence.
Regulatory sequences may include promoters, translation leader
sequences, introns, and polyadenylation recognition sequences.
[0098] "Promoter" refers to a nucleotide sequence capable of
controlling the expression of a coding sequence or functional RNA.
In general, a coding sequence is located 3' to a promoter sequence.
The promoter sequence consists of proximal and more distal upstream
elements, the latter elements often referred to as enhancers.
Accordingly, an "enhancer" is a nucleotide sequence, which can
stimulate promoter activity and may be an innate element of the
promoter or a heterologous element inserted to enhance the level or
tissue-specificity of a promoter. Promoters may be derived in their
entirety from a native gene, or may be composed of different
elements derived from different promoters found in nature, or may
even comprise synthetic nucleotide segments. It is understood by
those skilled in the art that different promoters may direct the
expression of a gene in different tissues or cell types, or at
different stages of development, or in response to different
environmental conditions. Promoters which cause a nucleic acid
fragment to be expressed in most cell types at most times are
commonly referred to as "constitutive promoters". New promoters of
various types useful in plant cells are constantly being
discovered; numerous examples may be found in the compilation by
Okamuro and Goldberg (1989) Biochemistry of Plants 15:1-82. It is
further recognized that since in most cases the exact boundaries of
regulatory sequences have not been completely defined, nucleic acid
fragments of different lengths may have identical promoter
activity.
[0099] "Convergent promoters" refers to promoters that are situated
on either side of the isolated nucleic acid fragment of interest
such that the direction of transcription from each promoter is
opposing each other. Any promoter useful in plant transgene
expression can be used. The promoters can be the same or different.
The promoters are convergent with the isolated nucleic acid
fragment being situated between the convergent promoters. It is
important that the promoters have similar spatial and temporal
activity, i.e., similar spatial and temporal patterns of
expression, so that double-stranded RNA is produced in plants or
plant organs by the recombinant construct that is stably integrated
into the genome of the plant or plant organ. This has been
described in U.S. provisional application 60/578,404, filed Jun. 9,
2004 which is filed simultaneously herewith. Also, this is
described in U.S. provisional application 60/625,835, filed Nov. 8,
2004.
[0100] "Translation leader sequence" refers to a nucleotide
sequence located between the promoter sequence of a gene and the
coding sequence. The translation leader sequence is present in the
fully processed mRNA upstream of the translation start sequence.
The translation leader sequence may affect processing of the
primary transcript to mRNA, mRNA stability or translation
efficiency. Examples of translation leader sequences have been
described (Turner and Foster (1995) Mol. Biotechnol.
3:225-236).
[0101] "3' non-coding sequences" refer to nucleotide sequences
located downstream of a coding sequence and include polyadenylation
recognition sequences and other sequences encoding regulatory
signals capable of affecting mRNA processing or gene expression.
The polyadenylation signal is usually characterized by affecting
the addition of polyadenylic acid tracts to the 3' end of the mRNA
precursor. The use of different 3' non-coding sequences is
exemplified by Ingelbrecht et al. (1989) Plant Cell 1:671-680.
[0102] "RNA transcript" refers to the product resulting from RNA
polymerase-catalyzed transcription of a DNA sequence. When the RNA
transcript is a perfect complementary copy of the DNA sequence, it
is referred to as the primary transcript or it may be a RNA
sequence derived from posttranscriptional processing of the primary
transcript and is referred to as the mature RNA. "Messenger RNA
(mRNA)" refers to the RNA that is without introns and that can be
translated into polypeptides by the cell. "cDNA" refers to DNA that
is complementary to and derived from an mRNA template. The cDNA can
be single-stranded or converted to double stranded form using, for
example, the Klenow fragment of DNA polymerase 1. "Sense-RNA"
refers to an RNA transcript that includes the mRNA and so can be
translated into a polypeptide by the cell. "Antisense RNA" refers
to an RNA transcript that is complementary to all or part of a
target primary transcript or mRNA and that blocks the expression of
a target gene (see U.S. Pat. No. 5,107,065, incorporated herein by
reference). The complementarity of an antisense RNA may be with any
part of the specific nucleotide sequence, i.e., at the 5'
non-coding sequence, 3' non-coding sequence, introns, or the coding
sequence. "Functional RNA" refers to sense RNA, antisense RNA,
ribozyme RNA, or other RNA that may not be translated but yet has
an effect on cellular processes.
[0103] Cosuppression technology constitutes the subject matter of
U.S. Pat. No. 5,231,020, which issued to Jorgensen et al. on Jul.
27, 1999. The phenomenon observed by Napoli et al. in petunia was
referred to as "cosuppression" since expression of both the
endogenous gene and the introduced transgene were suppressed (for
reviews see Vaucheret et al., Plant J. 16:651-659 (1998); and Gura,
Nature 404:804-808 (2000)).
[0104] Co-suppression constructs in plants previously have been
designed by focusing on overexpression of a nucleic acid sequence
having homology to an endogenous mRNA, in the sense orientation,
which results in the reduction of all RNA having homology to the
overexpressed sequence (see Vaucheret et al. (1998) Plant J
16:651-659; and Gura (2000) Nature 404:804-808). The overall
efficiency of this phenomenon is low, and the extent of the RNA
reduction is widely variable. Recent work has described the use of
"hairpin" structures that incorporate all, or part, of an mRNA
encoding sequence in a complementary orientation that results in a
potential "stem-loop" structure for the expressed RNA (PCT
Publication WO 99/53050 published on Oct. 21, 1999). This increases
the frequency of co-suppression in the recovered transgenic plants.
Another variation describes the use of plant viral sequences to
direct the suppression, or "silencing", of proximal mRNA encoding
sequences (PCT Publication WO 98/36083 published on Aug. 20, 1998).
Both of these co-suppressing phenomena have not been elucidated
mechanistically, although recent genetic evidence has begun to
unravel this complex situation (Elmayan et al. (1998) Plant Cell
10:1747-1757).
[0105] In addition to cosuppression, antisense technology has also
been used to block the function of specific genes in cells.
Antisense RNA is complementary to the normally expressed RNA, and
presumably inhibits gene expression by interacting with the normal
RNA strand. The mechanisms by which the expression of a specific
gene are inhibited by either antisense or sense RNA are on their
way to being understood. However, the frequencies of obtaining the
desired phenotype in a transgenic plant may vary with the design of
the construct, the gene, the strength and specificity of its
promoter, the method of transformation and the complexity of
transgene insertion events (Baulcombe, Curr. Biol. 12(3):R82-84
(2002); Tang et al., Genes Dev. 17(1):49-63 (2003); Yu et al.,
Plant Cell. Rep. 22(3):167-174 (2003)). Cosuppression and antisense
inhibition are also referred to as "gene silencing",
"post-transcriptional gene silencing" (PTGS), RNA interference or
RNAi. See for example U.S. Pat. No. 6,506,559.
[0106] MicroRNAs (miRNA) are small regulatory RNSs that control
gene expression. miRNAs bind to regions of target RNAs and inhibit
their translation and, thus, interfere with production of the
polypeptide encoded by the target RNA. miRNAs can be designed to be
complementary to any region of the target sequence RNA including
the 3' untranslated region, coding region, etc. miRNAs are
processed from highly structured RNA precursors that are processed
by the action of a ribonuclease III termed DICER. While the exact
mechanism of action of miRNAs is unknown, it appears that they
function to regulate expression of the target gene. See, e.g., U.S.
Patent Publication No. 2004/0268441 Al which was published on Dec.
30, 2004.
[0107] The term "operably linked" refers to the association of two
or more nucleic acid fragments on a single polynucleotide so that
the function of one is affected by the other. For example, a
promoter is operably linked with a coding sequence when it is
capable of affecting the expression of that coding sequence (i.e.,
that the coding sequence is under the transcriptional control of
the promoter). Coding sequences can be operably linked to
regulatory sequences in sense or antisense orientation.
[0108] The term "expression", as used herein, refers to the
transcription and stable accumulation of sense (mRNA) or antisense
RNA derived from the nucleic acid fragment of the invention.
Expression may also refer to translation of mRNA into a
polypeptide. "Antisense inhibition" refers to the production of
antisense RNA transcripts capable of suppressing the expression of
the target protein. "Overexpression" refers to the production of a
gene product in transgenic organisms that exceeds levels of
production in normal or non-transformed organisms. "Co-suppression"
refers to the production of sense RNA transcripts capable of
suppressing the expression of identical or substantially similar
foreign or endogenous genes (U.S. Pat. No. 5,231,020, incorporated
herein by reference).
[0109] A "protein" or "polypeptide" is a chain of amino acids
arranged in a specific order determined by the coding sequence in a
polynucleotide encoding the polypeptide. Each protein or
polypeptide has a unique function.
[0110] "Altered levels" or "altered expression" refers to the
production of gene product(s) in transgenic organisms in amounts or
proportions that differ from that of normal or non-transformed
organisms.
[0111] "Mature protein" or the term "mature" when used in
describing a protein refers to a post-translationally processed
polypeptide; i.e., one from which any pre- or pro-peptides present
in the primary translation product have been removed. "Precursor
protein" or the term "precursor" when used in describing a protein
refers to the primary product of translation of mRNA; i.e., with
pre- and pro-peptides still present. Pre- and pro-peptides may be
but are not limited to intracellular localization signals.
[0112] "Transformation" refers to the transfer of a nucleic acid
fragment into the genome of a host organism, resulting in
genetically stable inheritance. Host organisms containing the
transformed nucleic acid fragments are referred to as "transgenic"
organisms. Examples of methods of plant transformation include
Agrobacterium-mediated transformation (De Blaere et al. (1987)
Meth. Enzymol. 143:277) and particle-accelerated or "gene gun"
transformation technology (Klein et al. (1987) Nature (London)
327:70-73; U.S. Pat. No. 4,945,050, incorporated herein by
reference). Thus, isolated polynucleotides of the present invention
can be incorporated into recombinant constructs, typically DNA
constructs, capable of introduction into and replication in a host
cell. Such a construct can be a vector that includes a replication
system and sequences that are capable of transcription and
translation of a polypeptide-encoding sequence in a given host
cell. A number of vectors suitable for stable transfection of plant
cells or for the establishment of transgenic plants have been
described in, e.g., Pouwels et al., Cloning Vectors: A Laboratory
Manual, 1985, supp. 1987; Weissbach and Weissbach, Methods for
Plant Molecular Biology, Academic Press, 1989; and Flevin et al.,
Plant Molecular Biology Manual, Kluwer Academic Publishers, 1990.
Typically, plant expression vectors include, for example, one or
more cloned plant genes under the transcriptional control of 5' and
3' regulatory sequences and a dominant selectable marker. Such
plant expression vectors also can contain a promoter regulatory
region (e.g., a regulatory region controlling inducible or
constitutive, environmentally- or developmentally-regulated, or
cell- or tissue-specific expression), a transcription initiation
start site, a ribosome binding site, an RNA processing signal, a
transcription termination site, and/or a polyadenylation
signal.
[0113] "Stable transformation" refers to the transfer of a nucleic
acid fragment into a genome of a host organism, including both
nuclear and organellar genomes, resulting in genetically stable
inheritance. The term "transformation" as used herein refers to
both stable transformation and transient transformation.
[0114] The terms "recombinant construct", "expression construct"
and "recombinant expression construct" are used interchangeably
herein. These terms refer to a functional unit of genetic material
that can be inserted into the genome of a cell using standard
methodology well known to one skilled in the art.
[0115] The term "vector" refers to a vehicle used for gene cloning
to insert a foreign nucleic acid fragment into the genome of a host
cell.
[0116] Standard recombinant DNA and molecular cloning techniques
used herein are well known in the art and are described more fully
in Sambrook et al. Molecular Cloning: A Laboratory Manual; Cold
Spring Harbor Laboratory Press: Cold Spring Harbor, 1989
(hereinafter "Maniatis").
[0117] "Motifs" or "subsequences" refer to short regions of
conserved sequences of nucleic acids or amino acids that comprise
part of a longer sequence. For example, it is expected that such
conserved subsequences would be important for function, and could
be used to identify new homologues in plants. It is expected that
some or all elements may be found in a homologue. Also, it is
expected that one or two of the conserved amino acids in any given
motif may differ in a true homologue.
[0118] "PCR" or "polymerase chain reaction" is well known by those
skilled in the art as a technique used for the amplification of
specific DNA segments (U.S. Pat. Nos. 4,683,195 and 4,800,159).
[0119] The present invention concerns an isolated polynucleotide
comprising: [0120] (a) a nucleotide sequence encoding a polypeptide
having galactinol synthase activity, wherein the polypeptide has an
amino acid sequence of at least 85% identity, when compared to one
of SEQ ID NO: 2 or 4 or 95% identity when compared to one of SEQ ID
NO:6, based on the Clustal V method of alignment, [0121] (b) all or
part of the isolated polynucleotide comprising (a) for use in
co-suppression or antisense suppression of endogenous nucleic acid
sequences encoding polypeptides having galactinol synthase
activity, or [0122] (c) a complement of the nucleotide sequence of
(a) or (b), wherein the complement and the nucleotide sequence
consist of the same number of nucleotides and are 100%
complementary.
[0123] This invention also includes the isolated complement of such
polynucleotides, wherein the complement and the polynucleotide
consist of the same number of nucleotides, and the nucleotide
sequence of the complement and the polynucleotide have 100%
complementarity.
[0124] Nucleic acid fragments encoding at least a portion of
several galactinol synthases have been isolated and identified by
comparison of random plant cDNA sequences to public databases
containing nucleotide and protein sequences using the BLAST
algorithms well known to those skilled in the art. The nucleic acid
fragments of the instant invention may be used to isolate cDNAs and
genes encoding homologous proteins from the same or other plant
species. Isolation of homologous genes using sequence-dependent
protocols is well known in the art. Examples of sequence-dependent
protocols include, but are not limited to, methods of nucleic acid
hybridization, and methods of DNA and RNA amplification as
exemplified by various uses of nucleic acid amplification
technologies (e.g., polymerase chain reaction, ligase chain
reaction).
[0125] For example, genes encoding other galactinol synthases,
either as cDNAs or genomic DNAs, could be isolated directly by
using all or a portion of the instant nucleic acid fragments as DNA
hybridization probes to screen libraries from any desired plant
employing methodology well known to those skilled in the art.
Specific oligonucleotide probes based upon the instant nucleic acid
sequences can be designed and synthesized by methods known in the
art (Maniatis). Moreover, an entire sequence can be used directly
to synthesize DNA probes by methods known to the skilled artisan
such as random primer DNA labeling, nick translation, end-labeling
techniques, or RNA probes using available in vitro transcription
systems. In addition, specific primers can be designed and used to
amplify a part or all of the instant sequences. The resulting
amplification products can be labeled directly during amplification
reactions or labeled after amplification reactions, and used as
probes to isolate full length cDNA or genomic fragments under
conditions of appropriate stringency.
[0126] In addition, two short segments of the instant nucleic acid
fragments may be used in polymerase chain reaction protocols to
amplify longer nucleic acid fragments encoding homologous genes
from DNA or RNA. The polymerase chain reaction may also be
performed on a library of cloned nucleic acid fragments wherein the
sequence of one primer is derived from the instant nucleic acid
fragments, and the sequence of the other primer takes advantage of
the presence of the polyadenylic acid tracts to the 3' end of the
mRNA precursor encoding plant genes. Alternatively, the second
primer sequence may be based upon sequences derived from the
cloning vector. For example, the skilled artisan can follow the
RACE protocol (Frohman et al. (1988) Proc. Natl. Acad. Sci. USA
85:8998-9002) to generate cDNAs by using PCR to amplify copies of
the region between a single point in the transcript and the 3' or
5' end. Primers oriented in the 3' and 5' directions can be
designed from the instant sequences. Using commercially available
3' RACE or 5' RACE systems (BRL), specific 3' or 5' cDNA fragments
can be isolated (Ohara et al. (1989) Proc. Natl. Acad. Sci. USA
86:5673-5677; Loh et al. (1989) Science 243:217-220). Products
generated by the 3' and 5' RACE procedures can be combined to
generate full-length cDNAs (Frohman and Martin (1989) Techniques
1:165). Consequently, a polynucleotide comprising a nucleotide
sequence of at least 30 (preferably at least 40, most preferably at
least 60) contiguous nucleotides derived from a nucleotide sequence
selected from the group consisting of SEQ ID NOs:1, 3, or 5 and the
complement of such nucleotide sequences may be used in such methods
to obtain a nucleic acid fragment encoding a substantial portion of
an amino acid sequence of a galactinol synthase polypeptide.
[0127] Availability of the instant nucleotide and deduced amino
acid sequences facilitates immunological screening of cDNA
expression libraries. Synthetic peptides representing portions of
the instant amino acid sequences may be synthesized. These peptides
can be used to immunize animals to produce polyclonal or monoclonal
antibodies with specificity for peptides or proteins comprising the
amino acid sequences. These antibodies can be then be used to
screen cDNA expression libraries to isolate full-length cDNA clones
of interest (Lerner (1984) Adv. Immunol. 36:1-34; Maniatis).
[0128] In another embodiment, this invention concerns viruses and
host cells comprising either the recombinant DNA constructs of the
invention as described herein or isolated polynucleotides of the
invention as described herein. Examples of host cells which can be
used to practice the invention include, but are not limited to,
yeast, bacteria, and plants.
[0129] Plant tissue includes differentiated and undifferentiated
tissues or plants, including but not limited to, roots, stems,
shoots, leaves, pollen, seeds, tumor tissue, and various forms of
cells and culture such as single cells, protoplasm, embryos, and
callus tissue. The plant tissue may in plant or in organ, tissue or
cell culture.
[0130] The term "plant organ" refers to plant tissue or group of
tissues that constitute a morphologically and functionally distinct
part of a plant. The term "genome" refers to the following: 1. The
entire complement of genetic material (genes and non-coding
sequences) is present in each cell of an organism, or virus or
organelle. 2. A complete set of chromosomes inherited as a
(haploid) unit from one parent. The term "stably integrated" refers
to the transfer of a nucleic acid fragment into the genome of a
host organism or cell resulting in genetically stable
inheritance.
[0131] As was noted above, the nucleic acid fragments of the
instant invention may be used to create transgenic plants in which
the disclosed polypeptides are present at higher or lower levels
than normal or in cell types or developmental stages in which they
are not normally found. This would have the effect of altering the
level of galactinol synthase, galactinol, and raffinose saccharides
in those cells.
[0132] Overexpression of the proteins of the instant invention may
be accomplished by first constructing a recombinant DNA construct
in which the coding region is operably linked to a promoter capable
of directing expression of a gene in the desired tissues at the
desired stage of development. The recombinant DNA construct may
comprise promoter sequences and translation leader sequences
derived from the same genes. 3' Non-coding sequences encoding
transcription termination signals may also be provided. The instant
recombinant DNA construct may also comprise one or more introns in
order to facilitate gene expression of the recombinant DNA
construct.
[0133] Plasmid vectors comprising the instant isolated
polynucleotides) (or recombinant DNA constructs) may be
constructed. The choice of plasmid vector is dependent upon the
method that will be used to transform host plants. The skilled
artisan is well aware of the genetic elements that must be present
on the plasmid vector in order to successfully transform, select
and propagate host cells containing the recombinant DNA construct
or recombinant DNA construct. The skilled artisan will also
recognize that different independent transformation events will
result in different levels and patterns of expression (Jones et al.
(1985) EMBO J. 4:2411-2418; De Almeida et al. (1989) Mol. Gen.
Genetics 218:78-86), and thus that multiple events must be screened
in order to obtain lines displaying the desired expression level
and pattern. Such screening may be accomplished by Southern
analysis of DNA, Northern analysis of mRNA expression, Western
analysis of protein expression, or phenotypic analysis.
[0134] It may also be desirable to reduce or eliminate expression
of genes encoding the instant polypeptides in plants for some
applications. In order to accomplish this, a recombinant DNA
construct designed for co-suppression of the instant polypeptide
can be constructed by linking a gene or gene fragment encoding that
polypeptide to plant promoter sequences. Alternatively, a
recombinant DNA construct designed to express antisense RNA for all
or part of the instant nucleic acid fragment can be constructed by
linking the gene or gene fragment in reverse orientation to plant
promoter sequences. Either the co-suppression or antisense
recombinant DNA constructs could be introduced into plants via
transformation wherein expression of the corresponding endogenous
genes are reduced or eliminated.
[0135] Molecular genetic solutions to the generation of plants with
altered gene expression have a decided advantage over more
traditional plant breeding approaches. Changes in plant phenotypes
can be produced by specifically inhibiting expression of one or
more genes by antisense inhibition or cosuppression (U.S. Pat. Nos.
5,190,931, 5,107,065 and 5,283,323). An antisense or cosuppression
construct would act as a dominant negative regulator of gene
activity. While conventional mutations can yield negative
regulation of gene activity these effects are most likely
recessive. The dominant negative regulation available with a
transgenic approach may be advantageous from a breeding
perspective. In addition, the ability to restrict the expression of
a specific phenotype to the reproductive tissues of the plant by
the use of tissue specific promoters may confer agronomic
advantages relative to conventional mutations which may have an
effect in all tissues in which a mutant gene is ordinarily
expressed.
[0136] The person skilled in the art will know that special
considerations are associated with the use of antisense or
cosuppression technologies in order to reduce expression of
particular genes. For example, the proper level of expression of
sense or antisense genes may require the use of different
recombinant DNA constructs utilizing different regulatory elements
known to the skilled artisan. Once transgenic plants are obtained
by one of the methods described above, it will be necessary to
screen individual transgenics for those that most effectively
display the desired phenotype. Accordingly, the skilled artisan
will develop methods for screening large numbers of transformants.
The nature of these screens will generally be chosen on practical
grounds. For example, one can screen by looking for changes in gene
expression by using antibodies specific for the protein encoded by
the gene being suppressed, or one could establish assays that
specifically measure enzyme activity. A preferred method will be
one which allows large numbers of samples to be processed rapidly,
since it will be expected that a large number of transformants will
be negative for the desired phenotype.
[0137] In still another embodiment, the present invention concerns
a galactinol synthase polypeptide having an amino acid sequence
comprising at least 85% identical, based on the Clustal method of
alignment, to a polypeptide of SEQ ID NO:2 or 4 or at least 95%
identical to a polypeptide of SEQ ID NO:6. The instant polypeptides
(or portions thereof) may be produced in heterologous host cells,
particularly in the cells of microbial hosts, and can be used to
prepare antibodies to these proteins by methods well known to those
skilled in the art. The antibodies are useful for detecting the
polypeptides of the instant invention in situ in cells or in vitro
in cell extracts. Preferred heterologous host cells for production
of the instant polypeptides are microbial hosts. Microbial
expression systems and expression vectors containing regulatory
sequences that direct high level expression of foreign proteins are
well known to those skilled in the art. Any of these could be used
to construct a recombinant DNA construct for production of the
instant polypeptides. This recombinant DNA construct could then be
introduced into appropriate microorganisms via transformation to
provide high level expression of the encoded galactinol synthase.
An example of a vector for high level expression of the instant
polypeptides in a bacterial host is provided (Example 5).
[0138] All or a substantial portion of the polynucleotides of the
instant invention may also be used as probes for genetically and
physically mapping the genes that they are a part of, and used as
markers for traits linked to those genes. Such information may be
useful in plant breeding in order to develop lines with desired
phenotypes. For example, the instant nucleic acid fragments may be
used as restriction fragment length polymorphism (RFLP) markers.
Southern blots (Maniatis) of restriction-digested plant genomic DNA
may be probed with the nucleic acid fragments of the instant
invention. The resulting banding patterns may then be subjected to
genetic analyses using computer programs such as MapMaker (Lander
et al. (1987) Genomics 1:174-181) in order to construct a genetic
map. In addition, the nucleic acid fragments of the instant
invention may be used to probe Southern blots containing
restriction endonuclease-treated genomic DNAs of a set of
individuals representing parent and progeny of a defined genetic
cross. Segregation of the DNA polymorphisms is noted and used to
calculate the position of the instant nucleic acid sequence in the
genetic map previously obtained using this population (Botstein et
al. (1980) Am. J. Hum. Genet. 32:314-331).
[0139] The production and use of plant gene-derived probes for use
in genetic mapping is described in Bernatzky and Tanksley (1986)
Plant Mol. Biol. Reporter 4:37-41. Numerous publications describe
genetic mapping of specific cDNA clones using the methodology
outlined above or variations thereof. For example, F2 intercross
populations, backcross populations, randomly mated populations,
near isogenic lines, and other sets of individuals may be used for
mapping. Such methodologies are well known to those skilled in the
art.
[0140] Nucleic acid probes derived from the instant nucleic acid
sequences may also be used for physical mapping (i.e., placement of
sequences on physical maps; see Hoheisel et al. In: Nonmammalian
Genomic Analysis: A Practical Guide, Academic press 1996, pp.
319-346, and references cited therein).
[0141] Nucleic acid probes derived from the instant nucleic acid
sequences may be used in direct fluorescence in situ hybridization
(FISH) mapping (Trask (1991) Trends Genet. 7:149-154). Although
current methods of FISH mapping favor use of large clones (several
hundred kb; see Laan et al. (1995) Genome Res. 5:13-20),
improvements in sensitivity may allow performance of FISH mapping
using shorter probes.
[0142] A variety of nucleic acid amplification-based methods of
genetic and physical mapping may be carried out using the instant
nucleic acid sequences. Examples include allele-specific
amplification (Kazazian (1989) J. Lab. Clin. Med. 11:95-96),
polymorphism of PCR-amplified fragments (CAPS; Sheffield et al.
(1993) Genomics 16:325-332), allele-specific ligation (Landegren et
al. (1988) Science 241:1077-1080), nucleotide extension reactions
(Sokolov (1990) Nucleic Acid Res. 18:3671), Radiation Hybrid
Mapping (Walter et al. (1997) Nat. Genet. 7:22-28) and Happy
Mapping (Dear and Cook (1989) Nucleic Acid Res. 17:6795-6807). For
these methods, the sequence of a nucleic acid fragment is used to
design and produce primer pairs for use in the amplification
reaction or in primer extension reactions. The design of such
primers is well known to those skilled in the art. In methods
employing PCR-based genetic mapping, it may be necessary to
identify DNA sequence differences between the parents of the
mapping cross in the region corresponding to the instant nucleic
acid sequence. This, however, is generally not necessary for
mapping methods.
[0143] Loss of function mutant phenotypes may be identified for the
instant cDNA clones either by targeted gene disruption protocols or
by identifying specific mutants for these genes contained in a
maize population carrying mutations in all possible genes
(Ballinger and Benzer (1989) Proc. Natl. Acad. Sci. USA
86:9402-9406; Koes et al. (1995) Proc. Natl. Acad. Sci. USA
92:8149-8153; Bensen et al. (1995) Plant Cell 7:75-84). The latter
approach may be accomplished in two ways. First, short segments of
the instant nucleic acid fragments may be used in polymerase chain
reaction protocols in conjunction with a mutation tag sequence
primer on DNAs prepared from a population of plants in which
Mutator transposons or some other mutation-causing DNA element has
been introduced (see Bensen, supra). The amplification of a
specific DNA fragment with these primers indicates the insertion of
the mutation tag element in or near the plant gene encoding the
instant polypeptide. Alternatively, the instant nucleic acid
fragment may be used as a hybridization probe against PCR
amplification products generated from the mutation population using
the mutation tag sequence primer in conjunction with an arbitrary
genomic site primer, such as that for a restriction enzyme
site-anchored synthetic adaptor. With either method, a plant
containing a mutation in the endogenous gene encoding the instant
polypeptide can be identified and obtained. This mutant plant can
then be used to determine or confirm the natural function of the
instant polypeptides disclosed herein.
[0144] This invention also relates to a method of reducing the
raffinose saccharide content of soybean seeds by at least 30%, 40%,
50%, 60%, 70%, 80%, 90%, 95% or 100% or any integer percentage in
between 30% to 100%.
[0145] Raffinose saccharides are a group of D-galactose-containing
oligosaccharide derivatives of sucrose that are widely distributed
in plants. Raffinose saccharides are characterized by the following
general formula:
[O-.beta.-D-galactopyranosyl-(1.fwdarw.6).sub.n-.alpha.-glucopyr-
anosyl-(1.fwdarw.2)-.beta.-D-fructofuranoside where n=0 through n=4
are known respectively as sucrose, raffinose, stachyose, verbascose
and ajugose.
[0146] More specifically, this invention concerns method for
reducing the level of at least one raffinose saccharide in soybean
comprising: [0147] (a) constructing a recombinant DNA construct
comprising all or part of at least one isolated polynucleotide
comprising a nucleotide sequence encoding a polypeptide having
galactinol synthase activity for use in co-suppression or antisense
suppression of endogenous nucleic acid sequences encoding
polypeptides having galactinol synthase activity operably linked to
at least one regulatory sequence; and [0148] (b) transforming a
soybean cell with the recombinant DNA construct of (a); and [0149]
(c) regenerating soybean plants from the transformed cells of step
(c); and [0150] screening seeds obtained from the plants of (c) for
an altered level of galactinol synthase in the transformed soybean
cell when compared to a corresponding nontransformed soybean
cell.
[0151] The regeneration, development, and cultivation of plants
from single plant protoplast transformants or from various
transformed explants is well known in the art (Weissbach and
Weissbach, In: Methods for Plant Molecular Biology, (Eds.),
Academic Press, Inc. San Diego, Calif., (1988)). This regeneration
and growth process typically includes the steps of selection of
transformed cells, culturing those individualized cells through the
usual stages of embryonic development through the rooted plantlet
stage. Transgenic embryos and seeds are similarly regenerated. The
resulting transgenic rooted shoots are thereafter planted in an
appropriate plant growth medium such as soil. Preferably, the
regenerated plants are self-pollinated to provide homozygous
transgenic plants. Otherwise, pollen obtained from the regenerated
plants is crossed to seed-grown plants of agronomically important
lines. Conversely, pollen from plants of these important lines is
used to pollinate regenerated plants. A transgenic plant of the
present invention containing a desired polypeptide is cultivated
using methods well known to one skilled in the art.
[0152] There are a variety of methods for the regeneration of
plants from plant tissue. The particular method of regeneration
will depend on the starting plant tissue and the particular plant
species to be regenerated.
[0153] Methods for transforming dicots, primarily using
Agrobacterium tumefaciens, and obtaining transgenic plants have
been published for cotton (U.S. Pat. No. 5,004,863, U.S. Pat. No.
5,159,135, U.S. Pat. No. 5,518,908); soybean (U.S. Pat. No.
5,569,834, U.S. Pat. No. 5,416,011, McCabe et. al. (1988)

87:671-674); Brassica (U.S. Pat. No. 5,463,174); peanut (Cheng et
al. (1996) Plant Cell Rep. 15:653-657, McKently et al. (1995) Plant
Cell Rep. 14:699-703); papaya and pea (Grant et al. (1995) Plant
Cell Rep. 15:254-258).
[0154] Transformation of monocotyledons using electroporation,
particle bombardment, and Agrobacterium have also been reported.
Transformation and plant regeneration have been achieved in
asparagus (Bytebier et al., Proc. Natl. Acad. Sci. (USA) (1987)
84:5354); barley (Wan and Lemaux (1994) Plant Physiol. 104:37); Zea
mays (Rhodes et al. (1988) Science 240:204, Gordon-Kamm et al.

(Vasil et al. (1992) Bio/Technology 10:667; U.S. Pat. No.
5,631,152).
[0155] Assays for gene expression based on the transient expression
of cloned nucleic acid constructs have been developed by
introducing the nucleic acid molecules into plant cells by
polyethylene glycol treatment, electroporation, or particle
bombardment (Marcotte et al., Nature 335:454-457 (1988); Marcotte
et al., Plant Cell 1:523-532 (1989); McCarty et al., Cell
66:895-905 (1991); Hattori et al., Genes Dev. 6:609-618 (1992);
Goff et al., EMBO J. 9:2517-2522 (1990)).
[0156] Transient expression systems may be used to functionally
dissect isolated nucleic acid fragment constructs (see generally,
Maliga et al., Methods in Plant Molecular Biology, Cold Spring
Harbor Press (1995)). It is understood that any of the nucleic acid
molecules of the present invention can be introduced into a plant
cell in a permanent or transient manner in combination with other
genetic elements such as vectors, promoters, enhancers etc.
[0157] In addition to the above discussed procedures the standard
resource materials which describe specific conditions and
procedures for the construction, manipulation and isolation of
macromolecules (e.g., DNA molecules, plasmids, etc.), generation of
recombinant organisms and screening and isolating of clones (see
for example, Sambrook et al., Molecular Cloning: A Laboratory
Manual, Cold Spring Harbor Press (1989); Maliga et al., Methods in
Plant Molecular Biology, Cold Spring Harbor Press (1995); Birren et
al., Genome Analysis: Detecting Genes, 1, Cold Spring Harbor, N.Y.
(1998); Birren et al., Genome Analysis: Analyzing DNA, 2, Cold
Spring Harbor, N.Y. (1998); Plant Molecular Biology: A Laboratory

tissue was prepared. The characteristics of the library are
described below.

srr3c.pk001.i20:fis
[0161] cDNA libraries may be prepared by any one of many methods
available. For example, the cDNAs may be introduced into plasmid
vectors by first preparing the cDNA libraries in Uni-ZAP.TM. XR
vectors according to the manufacturer's protocol (Stratagene
Cloning Systems, La Jolla, Calif.). The Uni-ZAP.TM. XR libraries
are converted into plasmid libraries according to the protocol
provided by Stratagene. Upon conversion, cDNA inserts will be
contained in the plasmid vector pBluescript. In addition, the cDNAs
may be introduced directly into precut Bluescript II SK(+) vectors
(Stratagene) using T4 DNA ligase (New England Biolabs), followed by
transfection into DH10B cells according to the manufacturer's
protocol (GIBCO BRL Products). Once the cDNA inserts are in plasmid
vectors, plasmid DNAs are prepared from randomly picked bacterial
colonies containing recombinant pBluescript plasmids, or the insert
cDNA sequences are amplified via polymerase chain reaction using
primers specific for vector sequences flanking the inserted cDNA
sequences. Amplified insert DNAs or plasmid DNAs are sequenced in
dye-primer sequencing reactions to generate partial cDNA sequences
(expressed sequence tags or "ESTs"; see Adams et al., (1991)
Science 252:1651-1656). The resulting ESTs are analyzed using a
Perkin Elmer Model 377 fluorescent sequencer.
[0162] Full-insert sequence (FIS) data is generated utilizing a
modified transposition protocol. Clones identified for FIS are
recovered from archived glycerol stocks as single colonies, and
plasmid DNAs are isolated via alkaline lysis. Isolated DNA
templates are reacted with vector primed M13 forward and reverse
oligonucleotides in a PCR-based sequencing reaction and loaded onto
automated sequencers. Confirmation of clone identification is
performed by sequence alignment to the original EST sequence from
which the FIS request is made.
[0163] Confirmed templates are transposed via the Primer Island
transposition kit (PE Applied Biosystems, Foster City, Calif.)
which is based upon the Saccharomyces cerevisiae Ty1 transposable
element (Devine and Boeke (1994) Nucleic Acids Res. 22:3765-3772).
The in vitro transposition system places unique binding sites
randomly throughout a population of large DNA molecules. The
transposed DNA is then used to transform DH10B electro-competent
cells (Gibco BRL/Life Technologies, Rockville, Md.) via
electroporation. The transposable element contains an additional
selectable marker (named DHFR; Fling and Richards (1983) Nucleic
Acids Res. 11:5147-5158), allowing for dual selection on agar
plates of only those subclones containing the integrated
transposon. Multiple subclones are randomly selected from each
transposition reaction, plasmid DNAs are prepared via alkaline
lysis, and templates are sequenced (ABI Prism dye-terminator
ReadyReaction mix) outward from the transposition event site,
utilizing unique primers specific to the binding sites within the
transposon.
[0164] Sequence data is collected (ABI Prism Collections) and
assembled using Phred/Phrap (P. Green, University of Washington,
Seattle). Phrep/Phrap is a public domain software program which
re-reads the ABI sequence data, re-calls the bases, assigns quality
values, and writes the base calls and quality values into editable
output files. The Phrap sequence assembly program uses these
quality values to increase the accuracy of the assembled sequence
contigs. Assemblies are viewed by the Consed sequence editor (D.
Gordon, University of Washington, Seattle).
[0165] In some of the clones the cDNA fragment corresponds to a
portion of the 3'-terminus of the gene and does not cover the
entire open reading frame. In order to obtain the upstream
information one of two different protocols are used. The first of
these methods results in the production of a fragment of DNA
containing a portion of the desired gene sequence while the second
method results in the production of a fragment containing the
entire open reading frame. Both of these methods use two rounds of
PCR amplification to obtain fragments from one or more libraries.
The libraries some times are chosen based on previous knowledge
that the specific gene should be found in a certain tissue and some
times are randomly-chosen. Reactions to obtain the same gene may be
performed on several libraries in parallel or on a pool of
libraries. Library pools are normally prepared using from 3 to 5
different libraries and normalized to a uniform dilution. In the
first round of amplification both methods use a vector-specific
(forward) primer corresponding to a portion of the vector located
at the 5'-terminus of the clone coupled with a gene-specific
(reverse) primer. The first method uses a sequence that is
complementary to a portion of the already known gene sequence while
the second method uses a gene-specific primer complementary to a
portion of the 3'-untranslated region (also referred to as UTR). In
the second round of amplification a nested set of primers is used
for both methods. The resulting DNA fragment is ligated into a
pBluescript vector using a commercial kit and following the
manufacturer's protocol. This kit is selected from many available
from several vendors including Invitrogen (Carlsbad, Calif.),
Promega Biotech (Madison, Wis.), and Gibco-BRL (Gaithersburg, Md.).
The plasmid DNA is isolated by alkaline lysis method and submitted
for sequencing and assembly using Phred/Phrap, as above.
Example 2
Identification of cDNA Clones
[0166] cDNA clones encoding galactinol synthase were identified by
conducting BLAST (Basic Local Alignment Search Tool; Altschul et
al. (1993) J. Mol. Biol. 215:403-410;) searches for similarity to
sequences contained in the BLAST "nr" database (comprising all
non-redundant GenBank CDS translations, sequences derived from the
3-dimensional structure Brookhaven Protein Data Bank, the last
major release of the SWISS-PROT protein sequence database, EMBL,
and DDBJ databases). The cDNA sequences obtained in Example 1 were
analyzed for similarity to all publicly available DNA sequences
contained in the "nr" database using the BLASTN algorithm provided
by the National Center for Biotechnology Information (NCBI). The
DNA sequences were translated in all reading frames and compared
for similarity to all publicly available protein sequences
contained in the "nr" database using the BLASTX algorithm (Gish and
States (1993) Nat. Genet. 3:266-272) provided by the NCBI. For
convenience, the P-value (probability) of observing a match of a
cDNA sequence to a sequence contained in the searched databases
merely by chance as calculated by BLAST are reported herein as
"pLog" values, which represent the negative of the logarithm of the
reported P-value. Accordingly, the greater the pLog value, the
greater the likelihood that the cDNA sequence and the BLAST "hit"
represent homologous proteins.
[0167] ESTs submitted for analysis are compared to the GenBank
database as described above. ESTs that contain sequences more 5- or
3-prime can be found by using the BLAST algorithm (Altschul et al
(1997) Nucleic Acids Res. 25:3389-3402.) against the Du Pont
proprietary database comparing nucleotide sequences that share
common or overlapping regions of sequence homology. Where common or
overlapping sequences exist between two or more nucleic acid
fragments, the sequences can be assembled into a single contiguous
nucleotide sequence, thus extending the original fragment in either
the 5 or 3 prime direction. Once the most 5-prime EST is
identified, its complete sequence can be determined by Full Insert
Sequencing as described in Example 1. Homologous genes belonging to
different species can be found by comparing the amino acid sequence
of a known gene (from either a proprietary source or a public
database) against an EST database using the tBLASTn algorithm. The
tBLAST algorithm searches an amino acid query against a nucleotide
database that is translated in all 6 reading frames. This search
allows for differences in nucleotide codon usage between different
species, and for codon degeneracy.

Characterization of cDNA Clones Encoding Galactinol Synthase
[0168] The BLASTX search using the EST sequences from the clones
listed in Table 2 revealed similarity of the polypeptides encoded
by the cDNAs to galactinol synthase from Pisum sativum (NCBI
GenBank Identifier (GI) No. 5541885, SEQ ID NO:7), Arabidopsis
thaliana (NCBI GenBank Identifier (GI) No. 15223567, SEQ ID NO:8)
and Glycine max (NCBI GenBank Identifier (GI) No. 32345694, SEQ ID
NO:9). Shown in Table 2 are the BLAST results for the sequences
encoding an entire protein ("CGS") derived from the entire cDNA
inserts comprising the indicated cDNA clones ("fis"):

[0170] Sequence alignments and percent identity calculations were
performed using the Megalign program of the LASERGENE
bioinformatics computing suite (DNASTAR Inc., Madison, Wis.).
Multiple alignment of the sequences was performed using the Clustal
method of alignment (Higgins and Sharp (1989) CABIOS. 5:151-153)
with the default parameters (GAP PENALTY=10, GAP LENGTH
PENALTY=10). Default parameters for pairwise alignments using the
Clustal method were KTUPLE 1, GAP PENALTY=3, WINDOW=5 and DIAGONALS
SAVED=5. Sequence alignments and BLAST scores and probabilities
indicate that the nucleic acid fragments comprising the instant
cDNA clones encode a substantial portion of a galactinol synthase.
These sequences represent new soybean sequences encoding galactinol
synthase.
[0171] The expression pattern of galactinol synthase 3, 4 and 5
during soybean seed development was analyzed via Lynx MPSS Brenner
et al (2000) Proc Natl Acad Sci USA 97:1665-70) and is shown in
Table 4.

galactinol synthase 5 (srr3c.pk001.i20) during soybean seed
development (DAF = days after flowering, mature = mature seed).
[0172] The results shown in Table 4 demonstrate that expression of
all three galactinol synthases are only detectable during the later
stages of seed development (45 DAF to mature seed). Galactinol
synthase 4 is very lowly expressed compared to galactinol synthase
3 and 5, which show high and intermediate expression levels during
late seed development. The pattern of expression between galactinol
synthase 3 and 5 also differs: whereas galactinol synthase 3
expression levels increase during the course of late seed
development, reaching a plateau in the mature seed, galactinol
synthase 5 expression appears to be prominent mainly at 55 DAF and
in mature seed.
Example 4
Expression of Recombinant DNA Constructs in Dicot Cells
[0173] A seed-specific expression cassette composed of the promoter
and transcription terminator from the gene encoding the alpha
subunit of the seed storage protein phaseolin from the bean
Phaseolus vulgaris (Doyle et al. (1986) J. Biol. Chem.
261:9228-9238) can be used for expression of the instant
polypeptides in transformed soybean. The phaseolin cassette
includes about 500 nucleotides upstream (5') from the translation
initiation codon and about 1650 nucleotides downstream (3') from
the translation stop codon of phaseolin. Between the 5' and 3'
regions are the unique restriction endonuclease sites Nco I (which
includes the ATG translation initiation codon), Sma I, Kpn I and
Xba I. The entire cassette is flanked by Hind III sites.
[0174] The cDNA fragment of this gene may be generated by
polymerase chain reaction (PCR) of the cDNA clone using appropriate
oligonucleotide primers. Cloning sites can be incorporated into the
oligonucleotides to provide proper orientation of the DNA fragment
when inserted into the expression vector. Amplification is then
performed as described above, and the isolated fragment is inserted
into a pUC18 vector carrying the seed expression cassette.
[0175] Soybean embryos may then be transformed with the expression
vector comprising sequences encoding the instant polypeptides. To
induce somatic embryos, cotyledons, 3-5 mm in length dissected from
surface sterilized, immature seeds of the soybean cultivar A2872,
can be cultured in the light or dark at 26.degree. C. on an
appropriate agar medium for 6-10 weeks. Somatic embryos which
produce secondary embryos are then excised and placed into a
suitable liquid medium. After repeated selection for clusters of
somatic embryos which multiplied as early, globular staged embryos,
the suspensions are maintained as described below.
[0176] Soybean embryogenic suspension cultures can be maintained in
35 mL liquid media on a rotary shaker, 150 rpm, at 26.degree. C.
with florescent lights on a 16:8 hour day/night schedule. Cultures
are subcultured every two weeks by inoculating approximately 35 mg
of tissue into 35 mL of liquid medium.
[0177] Soybean embryogenic suspension cultures may then be
transformed by the method of particle gun bombardment (Klein et al.
(1987) Nature (London) 327:70-73, U.S. Pat. No. 4,945,050). A
DuPont Biolistic PDS1000/HE instrument (helium retrofit) can be
used for these transformations.
[0178] A selectable marker gene which can be used to facilitate
soybean transformation is a recombinant DNA construct composed of
the 35S promoter from Cauliflower Mosaic Virus (Odell et al. (1985)
Nature 313:810-812), the hygromycin phosphotransferase gene from
plasmid pJR225 (from E. coli; Gritz et al. (1983) Gene 25:179-188)
and the 3' region of the nopaline synthase gene from the T-DNA of
the Ti plasmid of Agrobacterium tumefaciens. The seed expression
cassette comprising the phaseolin 5' region, the fragment encoding
the instant polypeptide and the phaseolin 3' region can be isolated
as a restriction fragment. This fragment can then be inserted into
a unique restriction site of the vector carrying the marker
gene.
[0179] To 50 .mu.L of a 60 mg/mL 1 .mu.m gold particle suspension
is added (in order): 5 .mu.L DNA (1 .mu.g/.mu.L), 20 .mu.L
spermidine (0.1 M), and 50 .mu.L CaCl.sub.2 (2.5 M). The particle
preparation is then agitated for three minutes, spun in a microfuge
for 10 seconds and the supernatant removed. The DNA-coated
particles are then washed once in 400 .mu.L 70% ethanol and
resuspended in 40 .mu.L of anhydrous ethanol. The DNA/particle
suspension can be sonicated three times for one second each. Five
.mu.L of the DNA-coated gold particles are then loaded on each
macro carrier disk.
[0180] Approximately 300-400 mg of a two-week-old suspension
culture is placed in an empty 60.times.15 mm petri dish and the
residual liquid removed from the tissue with a pipette. For each
transformation experiment, approximately 5-10 plates of tissue are
normally bombarded. Membrane rupture pressure is set at 1100 psi
and the chamber is evacuated to a vacuum of 28 inches mercury. The
tissue is placed approximately 3.5 inches away from the retaining
screen and bombarded three times. Following bombardment, the tissue
can be divided in half and placed back into liquid and cultured as
described above.
[0181] Five to seven days post bombardment, the liquid media may be
exchanged with fresh media, and eleven to twelve days post
bombardment with fresh media containing 50 mg/mL hygromycin. This
selective media can be refreshed weekly. Seven to eight weeks post
bombardment, green transformed tissue may be observed growing from
untransformed, necrotic embryogenic clusters. Isolated green tissue
is removed and inoculated into individual flasks to generate new,
clonally propagated, transformed embryogenic suspension cultures.
Each new line may be treated as an independent transformation
event. These suspensions can then be subcultured and maintained as
clusters of immature embryos or regenerated into whole plants by
maturation and germination of individual somatic embryos.
Example 5
Expression of Recombinant DNA Constructs in Microbial Cells
[0182] The cDNAs encoding the instant polypeptides can be inserted
into the T7 E. coli expression vector pBT430. This vector is a
derivative of pET-3a (Rosenberg et al. (1987) Gene 56:125-135)
which employs the bacteriophage T7 RNA polymerase/T7 promoter
system. Plasmid pBT430 was constructed by first destroying the EcoR
I and Hind III sites in pET-3a at their original positions. An
oligonucleotide adaptor containing EcoR I and Hind III sites was
inserted at the BamH I site of pET-3a. This created pET-3aM with
additional unique cloning sites for insertion of genes into the
expression vector. Then, the Nde I site at the position of
translation initiation was converted to an Nco I site using
oligonucleotide-directed mutagenesis. The DNA sequence of pET-3aM
in this region, 5'-CATATGG, was converted to 5'-CCCATGG in
pBT430.
[0183] Plasmid DNA containing a cDNA may be appropriately digested
to release a nucleic acid fragment encoding the protein. This
fragment may then be purified on a 1% low melting agarose gel.
Buffer and agarose contain 10 .mu.g/mL ethidium bromide for
visualization of the DNA fragment. The fragment can then be
purified from the agarose gel by digestion with GELase (Epicentre
Technologies, Madison, Wis.) according to the manufacturer's
instructions, ethanol precipitated, dried and resuspended in 20 L
of water. Appropriate oligonucleotide adapters may be ligated to
the fragment using T4 DNA ligase (New England Biolabs (NEB),
Beverly, Mass.). The fragment containing the ligated adapters can
be purified from the excess adapters using low melting agarose as
described above. The vector pBT430 is digested, dephosphorylated
with alkaline phosphatase (NEB) and deproteinized with
phenol/chloroform as described above. The prepared vector pBT430
and fragment can then be ligated at 16.degree. C. for 15 hours
followed by transformation into DH5 electrocompetent cells (GIBCO
BRL). Transformants can be selected on agar plates containing LB
media and 100 .mu.g/mL ampicillin. Transformants containing the
gene encoding the instant polypeptide are then screened for the
correct orientation with respect to the T7 promoter by restriction
enzyme analysis.
[0184] For high level expression, a plasmid clone with the cDNA
insert in the correct orientation relative to the T7 promoter can
be transformed into E. coli strain BL21 (DE3) (Studier et al.
(1986) J. Mol. Biol. 189:113-130). Cultures are grown in LB medium
containing ampicillin (100 mg/L) at 25.degree. C. At an optical
density at 600 nm of approximately 1, IPTG
(isopropylthio-.beta.-galactoside, the inducer) can be added to a
final concentration of 0.4 mM and incubation can be continued for 3
h at 25.degree. C. Cells are then harvested by centrifugation and
re-suspended in 50 .mu.L of 50 mM Tris-HCl at pH 8.0 containing 0.1
mM DTT and 0.2 mM phenyl methylsulfonyl fluoride. A small amount of
1 mm glass beads can be added and the mixture sonicated 3 times for
about 5 seconds each time with a microprobe sonicator. The mixture
is centrifuged and the protein concentration of the supernatant
determined. One .mu.g of protein from the soluble fraction of the
culture can be separated by SDS-polyacrylamide gel electrophoresis.
Gels can be observed for protein bands migrating at the expected
molecular weight.
[0185] Crude, partially purified or purified enzyme, either alone
or as a fusion protein, may be utilized in assays for the
evaluation of enzymatic activity of the instant polypeptides
disclosed herein. Assays may be conducted under well-known
experimental conditions which permit optimal enzymatic activity.
Assays for galactinol synthase activity are presented by Odegard
and Lumen (1995) Plant Physiol. 109: 505-511.
Example 6
Construction of Chimeric Vectors for Seed-Targeted Co-Suppression
of Galactinol Synthase in Transgenic Glycine max
[0186] Vectors designed for the seed-specific co-suppression of
galactinol synthase 1 galactinol synthase 2 and galactinol synthase
3 in soybean were assembled as described below.
Amplification of Partial Galactinol Synthase Polynucleotides
[0187] Polynucleotide fragments encoding parts of the galactinol
synthase 1 (GAS1 (SEQ ID NO:6 of U.S. Pat. Nos. 5,773,699 and
5,648,210), galactinol synthase 2 (GAS2) in clone ses4d.pk0017.b8
(WO 01/77306) and galactinol synthase 3 (GAS3) in clone
sdp3c.pk013.c9 were amplified by standard PCR methods using Pfu
Turbo DNA polymerase (Stratagene, La Jolla, Calif.) and the
following primer sets. The GAS1 oligonucleotide primers were
designed to add a Not I restriction endonuclease site at the Send
and a XhoI site to the 3' end (SEQ ID NO:12 and SEQ ID NO:13,
respectively). The DNA sequence comprising the 519 bp
polynucleotide from soybean GAS1 is shown in SEQ ID NO:14.
[0188] The GAS2 oligonucleotide primers were designed to add a XhoI
restriction endonuclease site at the Send and a PstI site to the 3'
end (SEQ ID NO:15 and SEQ ID NO:16 respectively). The DNA sequence
comprising the 519 bp polynucleotide from soybean GAS2 is shown in
SEQ ID NO:17.
[0189] The GAS3 oligonucleotide primers were designed to add a PstI
restriction endonuclease site at the Send and a NotI site to the 3'
end (SEQ ID NO:18 and 19, respectively). The DNA sequence
comprising the 519 bp polynucleotide from soybean GAS3 is shown in
SEQ ID NO:20.
Assembly of Vectors for the Co-Suppression of Galactinol
Synthase
[0190] Preparation of pJMS08: The polynucleotide products for GAS1,
GAS2 and GAS3 obtained from the amplifications described above were
digested with Not I, Xho1 and PSt1 and assembled into vector pJMS08
(FIG. 2) by the following steps. First, the plasmid KS151 [US
patent publication 2003/0036197A1] was digested with Not I. Then,
the isolated DNA fragments containing partial sequences of GAS1,
GAS2 and GAS3 were inserted into Not I-digested plasmid KS151 to
obtain plasmid pJMS08 (FIG. 2).
[0191] Plasmid KS151 also comprises nucleotides encoding HPT under
the control of the T7 promoter and termination signals and the 35S
promoter and Nos 3' terminator (US patent publication
2003/0036197A1). The KTi3 promoter and 3' transcription terminator
region have been described by Jofuku et al. ((1989) Plant Cell
1:1079-1093). The KTI3 promoter directs strong embryo-specific
expression of transgenes.
[0192] Preparation of pJMS10: The polynucleotide products for GAS1,
GAS2 and GAS3 obtained from the amplifications described above were
digested with Not I, Xho1 and PSt1 and assembled into vector pJMS10
(FIG. 3) by the following steps. From plasmid KS123 (prepared
according to US Application No. 2004/0073975 A1, which published on
Apr. 15, 2004) the HindIII cassette containing the beta-conglycinin
promoter-phaseolin terminator was removed creating the plasmid
KS120. To the unique BamHI site of plasmid KS120 a lea
promoter-phaseolin terminator was inserted as a BamHI fragment
creating plasmid KS127. The Lea promoter (Lee et al (1992) Plant
Physiol. 100:2121-2122; Genbank Accession no. M97285) was amplified
from genomic A2872 soybean DNA and a phaseolin 3' end was added as
described in US patent publication 2003/0036197 A1. To KS127 an EL
linker was added to a unique Not1 site as described in US patent
publication 2003/0036197 A1, creating plasmid KS139. To KS139 an EL
linker was added to a unique Not1 site as described in US patent
publication 2003/0036197 A1, creating plasmid KS147. Plasmid KS147
also comprises nucleotides encoding HPT under the control of the T7
promoter and termination signals and the 35S promoter and Nos 3'.
Then, the isolated DNA fragments containing partial sequences of
GAS1, GAS2 and GAS3 were inserted into the Not I-digested plasmid
KS147 to obtain plasmid pJMS10 (FIG. 3).
Example 7
Construction of Chimeric Vectors for Seed-Targeted Co-Suppression
of Galactinol Synthase in Transgenic Glycine max
[0193] Vectors designed for the seed-specific co-suppression of
galactinol synthase 3, galactinol synthase 4 and galactinol
synthase 5 in soybean can be assembled as described below.
Amplification of Partial Galactinol Synthase Polynucleotides
[0194] Polynucleotide fragments encoding parts of the galactinol
synthase 4 (SEQ ID NO: 3), galactinol synthase 5 (SEQ ID NO:5) and
galactinol synthase 3 (SEQ ID NO:1) are amplified by standard PCR
methods using Pfu Turbo DNA polymerase (Stratagene, La Jolla,
Calif.). Appropriate primer sets are chosen, giving polynucleotide
fragments of similar length as described for GAS1, 2 and 3 (Example
6), which is well within the routine skill in the art.
Assembly of Vectors for the Co-Suppression of Galactinol
Synthase
[0195] The assembly of vectors containing GAS 3, 4, and 5 for the
co-suppression of galactinol synthase is performed essentially as
described for GAS1, 2 and 3 in Example 6.
[0196] Transformation into soybean somatic embryos and carbohydrate
analysis will be performed as described below for GAS1, 2, and
3.
[0197] It is expected, that a similar reduction in Raffinose
Saccharides in soybean seeds will be observed using GAS 3, 4, 5 as
the one observed with GAS1, 2, and 3.
Example 8
Transformation of Soybean Somatic Embryos with Galactinol Synthase
Co-Suppression Vectors
[0198] To study the possibility of reducing Raffinose Family
Oligosaccharides (RFOs), soybean somatic embryos were transformed
with the seed-specific expression vectors pJMS08 (FIG. 2) or pJMS10
(FIG. 3) by the method of particle gun bombardment (Klein, T. M. et
al. (1987) Nature (London) 327:70-73; U.S. Pat. No. 4,945,050).
Soybean somatic embryos from the Jack cultivar were induced as
follows. Cotyledons (3 mm in length) were dissected from surface
sterilized, immature seeds and were cultured for an additional 6-10
weeks in the light at 26.degree. C. on a Murashige and Skoog media
containing 7 g/L agar and supplemented with 10 mg/mL 2,4-D.
Globular stage somatic embryos, which produced secondary embryos,
were then excised and placed into flasks containing liquid MS
medium supplemented with 2,4-D (10 mg/mL) and cultured in the light
on a rotary shaker. After repeated selection for clusters of
somatic embryos that multiplied as early, globular staged embryos,
the soybean embryogenic suspension cultures were maintained in 35
mL liquid media on a rotary shaker, 150 rpm, at 26.degree. C. with
fluorescent lights on a 16:8 hour day/night schedule. Cultures were
subcultured every two weeks by inoculating approximately 35 mg of
tissue into 35 mL of liquid medium.
[0199] Soybean embryogenic suspension cultures were then
transformed by the method of particle gun bombardment using a
DuPont Biolistic.TM. PDS1000/HE instrument (helium retrofit). To 50
.mu.L of a 60 mg/.mu.L 1 mm gold particle suspension were added (in
order): 5 .mu.L of 1 mg/.mu.L DNA (pJMS01 plus pJMS02, pRM02 plus
pRM03, pRM01, or pRM04), 20 .mu.L of 0.1 M spermidine, and 50 .mu.L
of 2.5 M CaCl.sub.2. The particle preparation was then agitated for
three minutes, spun in a microfuge for 10 seconds and the
supernatant removed. The DNA-coated particles were then washed once
in 400 .mu.L 70% ethanol and resuspended in 40 .mu.L of anhydrous
ethanol. The DNA/particle suspension was sonicated three times for
one second each. Five .mu.L of the DNA-coated gold particles was
then loaded on each macro carrier disk.
[0200] Approximately 300-400 mg of a two-week-old suspension
culture was placed in an empty 60.times.15-mm Petri dish and the
residual liquid removed from the tissue with a pipette. For each
transformation experiment, approximately 5 to 10 plates of tissue
were bombarded. Membrane rupture pressure was set at 1100 psi and
the chamber was evacuated to a vacuum of 28 inches mercury. The
tissue was placed approximately 3.5 inches away from the retaining
screen and bombarded three times. Following bombardment, the tissue
was divided in half and placed back into liquid and cultured as
described above.
[0201] Five to seven days post bombardment, the liquid media was
exchanged with fresh media, and eleven to twelve days post
bombardment with fresh media containing 50 mg/mL hygromycin. This
selective media was refreshed weekly. Seven to eight weeks post
bombardment, green, transformed tissue was observed growing from
untransformed, necrotic embryogenic clusters. Isolated green tissue
was removed and inoculated into individual flasks to generate new,
clonally propagated, transformed embryogenic suspension cultures.
Each new line was treated as an independent transformation event.
These suspensions were then subcultured and maintained as clusters
of immature embryos.
[0202] These immature soybean embryos were dried-down (by
transferring them into an empty small petridish that was seated on
top of a 10 cm petridish containing some agar gel to allow slow dry
down) to mimic the last stages of soybean seed development.
[0203] Dried-down embryos are capable of producing plants when
transferred to soil or soil-less media. Storage products produced
by embryos at this stage are similar in composition to storage
products produced by zygotic embryos at a similar stage of
development and most importantly the storage product profile is
predictive of plants derived from a somatic embryo line (WO
94/11516, published May 26, 1994)).
Example 9
Carbohydrate Analysis of Transgenic Soybean Somatic Embryos
[0204] The carbohydrate composition of transgenic somatic embryos
identified in Example 6 as containing the pJMS08 or pJMS10
cassettes was measured by high performance anion exchange
chromatography/pulsed amperometric detection (HPAE/PAD). Fresh
individual somatic embryos from transgenic lines were rapidly
washed in water, dried on a paper towel, and transferred into 1.5
mL microcentrifuge tubes. Ethanol (80%) was added to the tubes and
the samples were heated to 70.degree. C. for 15 minutes. The
samples were centrifuged at 14,000 rpm for 5 minutes at 4.degree.
C. and the supernatant collected. The pellet was re-extracted two
additional times with 80% ethanol at 70.degree. C. The supernatants
were combined, dried down in a speedvac, and the pellet
re-suspended in water.
[0205] For HPAE analysis, the extracts were filtered through a 0.2
.mu.m Nylon-66 filter (Rainin, Emeryville, Calif.) and analyzed by
HPAE/PAD using a DX500 anion exchange analyzer (Dionex, Sunnyvale,
Calif.) equipped with a 250.times.4 mm CarboPac PA1 anion exchange
column and a 25.times.4 mm CarboPac PA guard column. Soluble
carbohydrates were separated with a 25 minute linear gradient of
0.5 to 170 mM NaAc in 150 mM NaOH at a flow rate of 1.0 mL/min.
Soluble sugars were identified by comparison to standards (glucose,
fructose, sucrose, raffinose, stachyose, and verbascose) using
HPAE/PAD.
[0206] FIG. 4 and Table 5 show a typical carbohydrate profile
resulting from HPAE/PAD analysis of transgenic soybean somatic
embryos co-suppressing galactinol synthase. A clear reduction in
RFOs (raffinose, stachyose and vebascose) can be observed as
compared to FIG. 5 and wild type values in Table 5.
[0207] FIG. 5 shows a typical carbohydrate profile resulting from
HPAE/PAD analysis of a soybean somatic embryo showing a wild type
carbohydrate phenotype.
[0208] The results for two different events showing cosuppression
experiments of the three isoforms of Galactinol Synthases 1, 2, and
3 are shown in Table 5 above. For each event, 6 seeds were
analyzed. The results are expressed in .mu.mol/g dwt (sugar unit),
where the dry weight calculation was based on 7% moisture content
of seed.

Example 10
Isolation of Soybean PM29 Promoter
[0210] The promoter of a soybean seed maturation protein was
isolated using a polymerase chain reaction (PCR) based approach.
Soybean genomic DNA was digested to completion with a DNA
restriction enzyme that generates blunt ends (DraI, EcoRV, PvuII or
StuI, for example) according to standard protocols. The Universal
GenomeWalker.TM. kit from Clonetech.TM. (Product User Manual No.
PT3042-1) was used to ligate adaptors to the ends of the genomic
DNA fragments. Nested primers are also supplied in the Universal
GenomeWalker.TM. kit that are specific for the adaptor sequence
(AP1 and AP2, for the first and second adaptor primer,
respectively). Two gene specific primers (GSP1 and GSP2) were
designed for the soybean PM29 gene based on the 5' coding sequences
in PM29 cDNA in DuPont EST database. The oligonucleotide sequences
of the GSP1 and GSP2 primers (SEQ ID NO:21 and SEQ ID NO:22,
respectively) contain recognition sites for the restriction enzyme
BAMH I.
[0211] The AP2 primer from the Universal GenomeWalker.TM. kit
contains a Sal I restriction site. The AP1 and the GSP1 primers
were used in the first round PCR using each of the adaptor ligated
genomic DNA populations (DraI, EcoRV, PvuII or StuI) under
conditions defined in the GenomeWalker.TM. protocol. Cycle
conditions were 94.degree. C. for 4 minutes; 94.degree. C. for 2
seconds and 72.degree. C. for 3 minutes, 7 cycles; 94.degree. C.
for 2 seconds and 67.degree. C. for 3 minutes, 32 cycles;
67.degree. C. for 4 minutes. The products from each of the first
run PCRs were diluted 50-fold. One microliter from each of the
diluted products was used as templates for the second PCR with the
AP2 and GSP2 as primers. Cycle conditions were 94.degree. C. for 4
minutes; 94.degree. C. for 2 seconds and 72.degree. C. for 3
minutes, 5 cycles; 94.degree. C. for 2 seconds and 67.degree. C.
for 3 minutes, 20 cycles; 67.degree. C. for 3 minutes. Agarose gels
were run to determine which PCR gave an optimal fragment length. A
679 bp genomic fragment was detected and isolated from the
EcoRV-digested genomic DNA reaction. The genomic fragment was
digested with BamH I and Sal I and cloned into Bluescript KS.sup.+
vector for sequencing. Finally, sequencing data indicated that this
genomic fragment contained a 597 bp soybean PM29 promoter sequence
as shown in SEQ ID NO:23.
Example 11
Construction of Galactinol Synthase Silencing Plasmids Driven by
PM29
[0212] Two oligonucleotides were designed to re-amplify the PM29
promoter with either BamH I or Nco I sites (SEQ ID NO:24 and SEQ ID
NO:25, respectively). The re-amplified PM29 promoter fragment was
digested with BamH I and Nco I, purified and cloned into the BamH I
and Nco I sites of plasmid pG4G (FIG. 6) to make the fusion between
the soybean PM29 promoter-GUS fusion (pSH43). The plasmid pG4G has
been described in U.S. Pat. No. 5,968,793, the contents of which
are hereby incorporated by reference.
Preparation of SH55 and SH49:
[0213] Plasmid pSH43 (described above) was digested with NcoI,
filled in with vent polymerase (obtained from New England Biolabs
Inc.) and subsequently digested with BamHI (5' end of the
promoter). The resulting promoter fragment was isolated and cloned
into pBluescript II SK (+) (Stratagene, Inc.) previously cut with
XbaI (and filled in by vent polymerase) and BamHI creating the
plasmids pBluescriptPM29. This construct contains a unique Not1
site at the 3' end of the promoter. Two copies of the
Eag1-ELVISLIVES sequence (SEQ ID NO:26) were added on the 5' site
of the Not1 site as described in EP1297163 A2 (PCT Publication No.
WO 2002/000904, which published Jan. 3, 2002).
[0214] The promoter fragment was isolated using a BamHI/Not1
digestion and ligated into pJMS10 plasmid previously cut with BamH1
(partial) and Not1. The pJMS10 plasmid also contains the
complementary strand of SEQ ID NO:26 (SEQ ID NO:27) 3' of the Not1
site. This ligation resulted in the following plasmid: SH55 (PM29
promoter-ELEL-Not1-ELEL-Phaseolin terminator) and SH49. SH49 is
identical to SH55 with the exception of a truncated ELEL sequence
(SEQ ID NO:28) at the 3' border of the Not1. The truncated sequence
is missing the "tgacca" of the ELEL sequence at the 3' border of
the Not1 and was identified after sequence verification of the
plasmid and probably originated during the PCR amplification of the
ELEL linker. This truncation has no effect on the ability of
silencing the GAS genes as is evident from Example 12.
Preparation of SH50:
[0215] A Not1 fragment containing the partial sequences of soybean
GAS1 (SEQ ID NO:14), GAS2 (SEQ ID NO:17) and GAS3 (SEQ ID NO:20)
was digested from pJMS10 (described above) and then ligated into
SH49 previously digested with Not1, creating the plasmid SH50 (SEQ
ID NO:29 and FIG. 7).
Example 12
Raffinose Family Oligosaccharide (RFO) Analysis of PM29 Driven
Transgenic Soybean Somatic Embryos and Mature Seeds
[0216] Soybean somatic embryos were transformed with a
seed-preferred expression vector SH50 (SEQ ID NO:29 and FIG. 7) by
the method described in Example 8.
[0217] Raffinose Family Oligosaccharides (galactinol, raffinose,
stachyose, etc.) of transgenic somatic embryos and seeds containing
the PM29 promoter driven recombinant expression construct described
in Example 11 was measured by thin layer chromatography. Somatic
embryos or seed chips were extracted with hexane then dried. The
dried material was resuspended in 80% methanol, incubated at room
temperature for 1-2 hours, centrifuged, and 2 microliters of the
supernatant is spotted onto a TLC plate (Kieselgel 60 CF, from EM
Scientific, Gibbstown, N.J.; Catalog No. 13749-6). The TLC was run
in ethylacetate:isopropanol:20% acetic acid (3:4:4) for 1-1.5
hours. The air dried plates were sprayed with 2% sulfuric acid and
heated until the charred sugars were detected. As shown in FIG. 8
two lines show reduced levels of raffinose sugars (raffinose and
stachyose lowest bands) when compared to a to wild-type soybean.
The arrow indicates somatic embryos with reduced raffinose family
oligosaccharides. (WT=wild type control, S=sucrose, Rf=raffinose
and St=stachyose standard). FIG. 9 shows a TLC analysis of mature
seed chips from a soybean line transformed with SH50 and revealed
an almost complete reduction in raffinose and stachyose (RFO)
sugars in seeds when compared to wild-type soybean. The plate shows
that 13 out of 17 seeds from a single event show a dramatic
reduction in raffinose family oligosaccharides (RFO).
Carbohydrate Analysis of Transgenic Soybean Seeds
[0218] The carbohydrate composition of transgenic soybean seeds
containing the PM29 promoter driven recombinant expression
construct described in Example 11 (SH50) was measured by high
performance anion exchange chromatography/pulsed amperometric
detection (HPAE/PAD). Seed chips were extracted in ethanol (80%)
and heated to 70.degree. C. for 15 minutes. The samples were
centrifuged at 14,000 rpm for 5 minutes at 4.degree. C. and the
supernatant collected. The pellet was re-extracted two additional
times with 80% ethanol at 70.degree. C. The supernatants were
combined, dried down in a speedvac, and the pellet re-suspended in
water.
[0219] For HPAE analysis, the extracts were filtered through a 0.2
.mu.m Nylon-66 filter (Rainin, Emeryville, Calif.) and analyzed by
HPAE/PAD using a DX500 anion exchange analyzer (Dionex, Sunnyvale,
Calif.) equipped with a 250.times.4 mm CarboPac PA1 anion exchange
column and a 25.times.4 mm CarboPac PA guard column. Soluble
carbohydrates were separated with a 20 isocratic run in 150 mM NaOH
at a flow rate of 1.0 mL/min. Soluble sugars were identified by
comparison to standards (glucose, fructose, sucrose, raffinose,
stachyose, and verbascose) using HPAE/PAD.
[0220] A typical profile of a soybean mutant characterized by
highly reduced raffinose family oligosaccharides content (Hitz et
al. 2002. Plant Physiology Vol 128, pp 650-660) is shown in FIG. 10
(Mutant HE2, left). As a comparison, the carbohydrate profile of
soybeans transformed with SH50 as described in Example 12 is shown
on the right (Transgenic seed with HE2 phenotype). Furthermore, the
sucrose to RFO ratio of the transgenic and mutant was very similar
and more than 10 fold higher when compared to wild type. The %
decrease in RFO when compared to wild type of some transgenic seeds
are shown in Table 6 and indicate a % reduction ranging from 71% to
89%. In comparison, the percent reduction of the mutant was
85%.

Example 13
Construction of Galactinol Synthase Silencing Plasmids Driven by
.beta.-Conglycinin and KTI3
[0221] Plasmid pJMS10 (FIG. 3) was prepared as described in Example
6.
[0222] Preparation of Plasmid pDS3:
[0223] pKR57 (FIG. 11) (4479 bp; SEQ ID NO:30) was digested with
Eco RI and Not I, run on a 0.8%
Tris-Acetate-Ethylenediaminetetraacetic acid-agarose gel
(TAE-agarose gel) and a 3144 bp fragment containing the
.beta.-conglycinin promoter, an origin of replication and a gene
encoding ampicillin resistance was purified using the Qiagen gel
extraction kit. pKR63 (FIG. 12) (5010 bp; SEQ ID NO:31) was
digested with Eco RI and Not I, run on a 0.8% TAE-agarose gel and a
2270 bp fragment containing the KTi promoter was purified using the
Qiagen gel extraction kit. The isolated fragments were ligated
together and the ligation was transformed into E. coli and colonies
were selected on ampicillin. Bacterial colonies were selected and
grown overnight in LB media and appropriate antibiotic selection.
DNA was isolated from the resulting culture using a Qiagen miniprep
kit according to the manufacturer's protocol and then analyzed by
restriction digest. The resulting plasmid was named pDS1 (FIG. 13)
(5414 bp; SEQ ID NO:32).
[0224] pKR72 (FIG. 14) (7085 bp; SEQ ID NO:33) was digested with
Hind III, run on a 0.8% TAE-agarose gel and a 5303 bp fragment
containing a gene that encodes resistance to hygromycin operably
linked to a prokaryotic promoter and a gene that encodes resistance
to hygromycin operably linked to a eukaryotic promoter were
purified using the Qiagen gel extraction kit. The fragment was
ligated to itself and the ligation was transformed into E. coli and
colonies were selected on hygromycin. Bacterial colonies were
selected and grown overnight in LB media and appropriate antibiotic
selection. DNA was isolated from the resulting culture using a
Qiagen miniprep kit according to the manufacturer's protocol and
then analyzed by restriction digest. The resulting plasmid was
named pDS2 (FIG. 15) (5303 bp; SEQ ID NO:34).
[0225] pDS2 was digested with Sal I and the ends were
dephosphorylated with calf intestinal alkaline phosphatase (CIAP)
according to the manufacture's instructions (Stratagene, San Diego,
Calif.). pDS1 was digested with Sal I and Fsp I, run on a 0.8%
TAE-agarose gel and a 2728 bp fragment containing the KTi3 promoter
and the .beta.-conglycinin promoter in opposite orientations was
purified using the Qiagen gel extraction kit. The isolated
fragments were ligated together and the ligation was transformed
into E. coli and colonies were selected on hygromycin. Bacterial
colonies were selected and grown overnight in LB media and
appropriate antibiotic selection. DNA was isolated from the
resulting culture using a Qiagen miniprep kit according to the
manufacturer's protocol and then analyzed by restriction digest.
The resulting plasmids were named pDS3 [orientation 2 (FIG. 16, SEQ
ID NO: 35)].
[0226] Preparation of SH60:
[0227] pJMS10 (FIG. 3) was digested with Not1, run on a 0.8%
TAE-agarose gel and a 1585 bp DNA fragment (SEQ ID NO:37)
comprising the partial sequences of GAS1 (SEQ ID NO:14), GAS2 (SEQ
ID NO:17) and GAS3 (SEQ ID NO:20) was purified using the Qiagen gel
extraction kit. pDS3 (orientation 2) (FIG. 16, SEQ ID NO: 35) was
digested with Not1, run on a 0.8% TAE-agarose gel and a 8031 bp DNA
fragment was purified using the Qiagen gel extraction kit. The
isolated fragments were ligated together and the ligation was
transformed into E. coli and colonies were selected on hygromycin.
Bacterial colonies were selected and grown overnight in LB media
and appropriate antibiotic selection. DNA was isolated from the
resulting culture using a Qiagen miniprep kit according to the
manufacturer's protocol and then analyzed by restriction digest.
The resulting plasmid was named SH60 (FIG. 17, SEQ ID NO: 36).
Example 14
Reduction of Raffinose Family Oligosaccharide (RFO) in Transgenic
Soybean Somatic Embryos
[0228] SH60, as described in Example 13, was transformed into
soybean embryogenic suspension cultures using a protocol as
described in Example 8 above. Individual immature soybean embryos
were dried-down (by transferring them into an empty small petridish
that was seated on top of a 10 cm petridish containing some agar
gel to allow slow dry down) to mimic the last stages of soybean
seed development. Dried-down embryos are capable of producing
plants when transferred to soil or soil-less media. Storage
products produced by embryos at this stage are similar in
composition to storage products produced by zygotic embryos at a
similar stage of development and most importantly the storage
product profile is predictive of plants derived from a somatic
embryo line (PCT Publication No. WO 94/11516, which published on
May 26, 1994). Raffinose Family Oligosaccharides (raffinose,
stachyose) of transgenic somatic embryos containing the
B-conglycinin/KT13 driven (SH60) recombinant expression construct
described in Example 13 was measured by thin layer chromatography.
Somatic embryos were extracted with hexane then dried. The dried
material was re-suspended in 80% methanol, incubated at room
temperature for 1-2 hours, centrifuged, and 2 .mu.l of the
supernatant is spotted onto a TLC plate (Kieselgel 60 CF, from EM
Scientific, Gibbstown, N.J.; Catalog No. 13749-6). The TLC was run
methylacetate:isopropanol:20% acetic acid (3:4:4) for 1-1.5 hours.
The air dried plates were sprayed with 2% sulfuric acid and heated
until the charred sugars were detected. As shown in FIG. 18 the
embryos labeled "Low RFO embryos" show reduced levels of raffinose
sugars (raffinose and stachyose s) when compared to a to wild-type
soybean. Five out of eleven (45%) lines analyzed showed reduced
levels of RFOs, which is demonstrative of reduced galactinol
synthase expression (see Table 7).
