INCORPORATION OF SEQUENCE LISTING
[0002] The sequence listing file named "57978_seq_listing.txt",
which is 10,564 bytes (measured in MS-WINDOWS) which was
electronically filed and which was created on May, 1 2012 is

FIELD OF THE INVENTION
[0003] The present invention relates to alfalfa transgenic event
KK179-2. The invention also provides cells, plant parts, seeds,
plants, commodity products related to the event, and DNA molecules
that are unique to the event and were created by the insertion of
transgenic DNA into the genome of an alfalfa plant. The invention
further provides methods for detecting the presence of said alfalfa
event nucleotide sequences in a sample, probes and primers for use
in detecting nucleotide sequences that are diagnostic for the
presence of said alfalfa event.
BACKGROUND OF THE INVENTION
[0004] Alfalfa (Medicago sativa) is the most cultivated legume
worldwide, with the US being the top alfalfa producer. The methods
of biotechnology have been applied to alfalfa for improvement of
agronomic traits and the quality of the product. One such agronomic
trait is lignin content.
[0005] Lignin is the second most abundant terrestrial biopolymer
and accounts for 30% of the organic carbon. Lignin is crucial for
structural integrity of the cell wall and it imparts stiffness and
strength to the stem. Lignin content is inversely correlated with
forage digestibility for diary cattle. A reduction in lignin may be
achieved in transgenic plants by the expression of a RNA
suppression construct capable of providing such decrease while at
the same time provide increased alfalfa digestibility. The
expression of foreign genes or suppression molecules in plants is
known to be influenced by many factors, such as the regulatory
elements used, the chromosomal location of the transgene insert,
the proximity of any endogenous regulatory elements close to the
transgene insertion site, and environmental factors such as light
and temperature. For example, it has been observed that there may
be variation in the overall level of transgene suppression or in
the spatial or temporal pattern of transgene suppression between
similarly-produced events. For this reason, it is often necessary
to screen hundreds of independent transformation events in order to
ultimately identify one event useful for commercial agricultural
purposes. Such an event, once identified as having the desired
suppression phenotype, molecular characteristics and the improved
trait, may then be used for introgressing the improved trait into
other genetic backgrounds using plant breeding methods. The
resulting progeny would contain the transgenic event and would
therefore have the same characteristics for that trait of the
original transformant. This may be used to produce a number of
different crop varieties that comprise the improved trait and are
suitably adapted to specific local growing conditions.
[0006] It would be advantageous to be able to detect the presence
of transgene/genomic DNA of a particular plant in order to
determine whether progeny of a sexual cross contain the
transgene/genomic DNA of interest. In addition, a method for
detecting a particular plant would be helpful when complying with
regulations requiring the pre-market approval and labeling of foods
derived from the transgenic crop plants.
[0007] The presence or absence of a suppression element may be
detected by any well known nucleic acid detection method such as
the polymerase chain reaction (PCR) or DNA hybridization using
nucleic acid probes. These detection methods generally focus on
frequently used genetic elements, such as promoters, terminators,
marker genes, etc. As a result, such methods may not be useful for
discriminating between different transformation events,
particularly those produced using the same DNA construct unless the
sequence of chromosomal DNA adjacent to the inserted DNA ("flanking
DNA") is known. An event-specific PCR assay is discussed, for
example, by Taverniers et al. (J. Agric. Food Chem., 53: 3041-3052,
2005) in which an event-specific tracing system for transgenic
maize lines Bt11, Bt176, and GA21 and for canola event GT73 was
demonstrated. In this study, event-specific primers and probes were
designed based upon the sequences of the genome/transgene junctions
for each event. Transgenic plant event specific DNA detection
methods have also been described in U.S. Pat. Nos. 7,632, 985;
7,566,817; 7,368,241; 7,306,909; 7,718,373; 7,189,514, 7,807,357
and 7,820,392.

to positions 3620 through 3639 of SEQ ID NO: 6, FIG. 1 [F]), and
complements thereof; wherein a junction sequence is a nucleotide
sequence that spans the point at which heterologous DNA inserted
into the genome is linked to the alfalfa cell genomic DNA and
detection of this sequence in a biological sample containing
alfalfa DNA is diagnostic for the presence of the alfalfa event
KK179-2 DNA in said sample (FIG. 1). The alfalfa event KK179-2 and

DETAILED DESCRIPTION
[0032] The following definitions and methods are provided to better
define the present invention and to guide those of ordinary skill
in the art in the practice of the present invention. Unless
otherwise noted, terms are to be understood according to
conventional usage by those of ordinary skill in the relevant art.
Definitions of common terms in molecular biology may also be found
in Rieger et al., Glossary of Genetics: Classical and Molecular,
5th edition, Springer-Verlag: N.Y., 1991; and Lewin, Genes V,
Oxford University Press: New York, 1994.
[0033] The present invention provides transgenic alfalfa event
KK179-2. The term "event" as used herein refers to the plants,
seeds, progeny, cells, plant parts thereof, and DNA molecules
produced as a result of transgenic DNA integration into a plant's
genome at a particular location on a chromosome. Event KK179-2
refers to the plants, seeds, progeny, cells, plant parts thereof,
and DNA molecules produced as a result of the insertion of
transgenic DNA having a sequence provided herein as SEQ ID NO: 5
into a particular chromosomal location in the Medicago sativa
genome. A seed sample containing KK179-2 has been deposited with
American Type Culture Collection (ATCC) under Accession No.
PTA-11833.
[0034] As used herein, the term "alfalfa" means Medicago sativa and
includes all plant varieties that can be bred with alfalfa,
including wild alfalfa species. Alfalfa is also called medic, the
name of any plant of the genus Medicago Old World herbs with blue
or yellow flowers similar to those of the related clovers. Unlike
corn or soybean, alfalfa plants are autotetraploid; thus, each
trait is determined by genes residing on four chromosomes instead
of two. This complicates genetic research and also adds to the
difficulty of improving alfalfa. Commercial alfalfa seed is often
comprised of a mixture of clones that may constitute a synthetic
cultivar generated by random interpollination among the selected
clones, followed by one to three generations of open-pollination in
isolation. Additionally, a composite cultivar of alfalfa may also
be developed by blending see of two or more clones or
interpollinating clones in isolation. When forming a composite
cultivar, equal quantities of seed from each component clone would
be blended to form the initial breeder seed stock.
[0035] A transgenic "event" is produced by transformation of plant
cells with heterologous DNA, such as, a nucleic acid construct that
comprises the RNA suppression of a gene of interest, regeneration
of a population of independently transformed transgenic plants
resulting from the insertion of the transgene cassette into the
genome of the plant, and selection of a particular plant with
desirable molecular characteristics, such as insertion of the
transgene into a particular genome location. A plant comprising the
event can refer to the original transformant that includes the
transgene inserted into the particular location in the plant's
genome. A plant comprising the event can also refer to progeny of
the original transformant that retain the transgene at the same
particular location in the plant's genome. Such progeny may be
produced by a sexual outcross between the transformant, or its
progeny, and another plant. Such another plant may be a transgenic
plant comprising the same or a different transgene; or may be a
non-transgenic plant, such as one from a different variety. Even
after repeated back-crossing to a recurrent parent, the event DNA
from the transformed parent is present in the progeny of the cross
at the same genomic location.
[0036] A DNA molecule comprising event KK179-2 refers to a DNA
molecule comprising at least a portion of the inserted transgenic
DNA (provided as SEQ ID NO: 5) and at least a portion of the
flanking genomic DNA immediately adjacent to the inserted DNA. As
such, a DNA molecule comprising event KK179-2 has a nucleotide
sequence representing at least a portion of the transgenic DNA
insert and at least a portion of the particular region of the
genome of the plant into which the transgenic DNA was inserted. The
arrangement of the inserted DNA in event KK179-2 in relation to the
surrounding plant genome is specific and unique to event KK179-2
and as such the nucleotide sequence of such a DNA molecule is
diagnostic and identifying for event KK179-2. Examples of the
sequence of such a DNA molecule are provided herein as SEQ ID NO:
1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, and SEQ ID NO: 6. Such
a DNA molecule is also an integral part of the chromosome of a
plant that comprises event KK179-2 and may be passed on to
progenies of the plant.
[0037] As used herein, a "recombinant DNA molecule" is a DNA
molecule comprising a combination of DNA molecules that would not
naturally occur together and is the result of human intervention,
for example, a DNA molecule that is comprised of a combination of
at least two DNA molecules heterologous to each other, and/or a DNA
molecule that is artificially synthesized and comprises a
polynucleotide sequence that deviates from the polynucleotide
sequence that would normally exist in nature, and/or a DNA molecule
that comprises a transgene artificially incorporated into a host
cell's genomic DNA and the associated flanking DNA of the host
cell's genome. An example of a recombinant DNA molecule is a DNA
molecule described herein resulting from the insertion of the
transgene into the Medicago sativa genome, which may ultimately
result in the suppression of a recombinant RNA and/or protein
molecule in that organism. The nucleotide sequence or any fragment
derived therefrom would also be considered a recombinant DNA
molecule if the DNA molecule can be extracted from cells, or
tissues, or homogenate from a plant or seed or plant tissue; or can
be produced as an amplicon from extracted DNA or RNA from cells, or
tissues, or homogenate from a plant or seed or plant tissue, any of
which is derived from such materials derived from the event
KK179-2. For that matter, the junction sequences as set forth at
SEQ ID NO: 1 and SEQ ID NO: 2, and nucleotide sequences derived
from event KK179-2 that also contain these junction sequences are
considered to be recombinant DNA, whether these sequences are
present within the genome of the cells of event KK179-2 or present
in detectable amounts in tissues, progeny, biological samples or
commodity products derived from the event KK179-2. As used herein,
the term "transgene" refers to a polynucleotide molecule
artificially incorporated into a host cell's genome. Such transgene
may be heterologous to the host cell. The term "transgenic plant"
refers to a plant comprising such a transgene. A "transgenic plant"
includes a plant, plant part, a plant cell or seed whose genome has
been altered by the stable integration of recombinant DNA. A
transgenic plant includes a plant regenerated from an
originally-transformed plant cell and progeny transgenic plants
from later generations or crosses of a transformed plant. As a
result of such genomic alteration, the transgenic plant is
distinctly different from the related wild type plant. An example
of a transgenic plant is a plant described herein as comprising
event KK179-2.
[0038] As used herein, the term "heterologous" refers to a sequence
which is not normally present in a given host genome in the genetic
context in which the sequence is currently found. In this respect,
the sequence may be native to the host genome, but be rearranged
with respect to other genetic sequences within the host
sequence.
[0039] The present invention provides DNA molecules and their
corresponding nucleotide sequences. As used herein, the terms "DNA
sequence", "nucleotide sequence" and "polynucleotide sequence"
refer to the sequence of nucleotides of a DNA molecule, usually
presented from the 5' (upstream) end to the 3' (downstream) end.
The nomenclature used herein is that required by Title 37 of the
United States Code of Federal Regulations .sctn. 1.822 and set
forth in the tables in WIPO Standard ST.25 (1998), Appendix 2,
Tables 1 and 3. The present invention is disclosed with reference
to only one strand of the two nucleotide sequence strands that are
provided in transgenic event KK179-2. Therefore, by implication and
derivation, the complementary sequences, also referred to in the
art as the complete complement or the reverse complementary
sequences, are within the scope of the present invention and are
therefore also intended to be within the scope of the subject
matter claimed.
[0040] The nucleotide sequence corresponding to the complete
nucleotide sequence of the inserted transgenic DNA and substantial
segments of the Medicago sativa genomic DNA flanking either end of
the inserted transgenic DNA is provided herein as SEQ ID NO: 6. A
subsection of this is the inserted transgenic DNA provided as SEQ
ID NO: 5. The nucleotide sequence of the genomic DNA flanking the
5' end of the inserted transgenic DNA and a portion of the 5' end
of the inserted DNA is provided herein as SEQ ID NO: 3. The
nucleotide sequence of the genomic DNA flanking the 3' end of the
inserted transgenic DNA and a portion of the 3' end of the inserted
DNA is provided herein as SEQ ID NO: 4. The region spanning the
location where the transgenic DNA connects to and is linked to the
genomic DNA is referred to herein as the junction. A "junction
sequence" or "junction region" refers to a DNA sequence and/or
corresponding DNA molecule that spans the inserted transgenic DNA
and the adjacent flanking genomic DNA. Examples of a junction
sequence of event KK179-2 are provided herein as SEQ ID NO: 1 and
SEQ ID NO: 2. The identification of one of these junction sequences
in a nucleotide molecule derived from a alfalfa plant or seed is
conclusive that the DNA was obtained from event KK179-2 and is
diagnostic for the presence of DNA from event KK179-2. SEQ ID NO: 1
is a 20 bp nucleotide sequence spanning the junction between the
genomic DNA and the 5' end of the inserted DNA. SEQ ID NO: 2 is a
20 bp nucleotide sequence spanning the junction between the genomic
DNA and the 3' end of the inserted DNA. Any segment of DNA derived
from transgenic event KK179-2 that includes the consecutive
nucleotides of SEQ ID NO: 1 is within the scope of the present
invention. Any segment of DNA derived from transgenic event KK179-2
that includes the consecutive nucleotides of SEQ ID NO: 2 is within
the scope of the present invention. In addition, any polynucleotide
molecule comprising a sequence complementary to any of the
sequences described within this paragraph is within the scope of
the present invention. FIG. 1 is an illustration of the transgenic
DNA insert in the genome of alfalfa event KK179-2, and the relative
positions of SEQ ID NOs: 1-6 arranged 5' to 3'.
[0041] The present invention further provides exemplary DNA
molecules that can be used either as primers or probes for
diagnosing the presence of DNA derived from event KK179-2 in a
sample. Such primers or probes are specific for a target nucleic
acid sequence and as such are useful for the identification of
event KK179-2 nucleic acid sequence by the methods of the invention
described herein.
[0042] A "probe" is an isolated nucleic acid to which is attached a
detectable label or reporter molecule, for example, a radioactive
isotope, ligand, chemiluminescent agent, or enzyme. Such a probe is
complementary to a strand of a target nucleic acid, in the case of
the present invention, to a strand of genomic DNA from alfalfa
event KK179-2 whether from a alfalfa plant or from a sample that
comprises DNA from the event. Probes according to the present
invention include not only deoxyribonucleic or ribonucleic acids
but also polyamides and other probe materials that bind
specifically to a target DNA sequence and the detection of such
binding can be used to diagnose/determine/confirm the presence of
that target DNA sequence in a particular sample.
[0043] A "primer" is typically an isolated polynucleotide that is
designed for use in specific annealing or hybridization methods to
hybridize to a complementary target DNA strand to form a hybrid
between the primer and the target DNA strand, and then extended
along the target DNA strand by a polymerase, for example, a DNA
polymerase. A pair of primers may be used with template DNA, such
as a sample of Medicago sativa genomic DNA, in a thermal or
isothermal amplification, such as polymerase chain reaction (PCR),
or other nucleic acid amplification methods, to produce an
amplicon, where the amplicon produced from such reaction would have
a DNA sequence corresponding to sequence of the template DNA
located between the two sites where the primers hybridized to the
template. As used herein, an "amplicon" is a piece or fragment of
DNA that has been synthesized using amplification techniques, such
as the product of an amplification reaction. In one embodiment of
the invention, an amplicon diagnostic for event KK179-2 comprises a
sequence not naturally found in the Medicago sativa genome. Primer
pairs, as used in the present invention, are intended to refer to
use of two primers binding opposite strands of a double stranded
nucleotide segment for the purpose of amplifying linearly the
polynucleotide segment between the positions targeted for binding
by the individual members of the primer pair, typically in a
thermal or isothermal amplification reaction or other nucleic acid
amplification methods. Exemplary DNA molecules useful as primers
are provided as SEQ ID NOs: 7-9, may be used as a first DNA
molecule and a second DNA molecule that is different from the first
DNA molecule, and both molecules are each of sufficient length of
consecutive nucleotides of either SEQ ID NO: 4, SEQ ID NO: 5, or
SEQ ID NO: 6 or the complements thereof to function as DNA primers
so that, when used together in an amplification reaction with
template DNA derived from event KK179-2, an amplicon that is
specific and unique to transgenic event KK179-2 would be produced.
The use of the term "amplicon" specifically excludes primer-dimers
that may be formed in the DNA amplification reaction.
[0044] Probes and primers according to the present invention may
have complete sequence identity to the target sequence, although
primers and probes differing from the target sequence that retain
the ability to hybridize preferentially to target sequences may be
designed by conventional methods. In order for a nucleic acid
molecule to serve as a primer or probe it needs only be
sufficiently complementary in sequence to be able to form a stable
double-stranded structure under the particular solvent and salt
concentrations employed. Any nucleic acid hybridization or
amplification method can be used to identify the presence of
transgenic DNA from event KK179-2 in a sample. Probes and primers
are generally at least about 11 nucleotides, at least about 18
nucleotides, at least about 24 nucleotides, and at least about 30
nucleotides or more in length. Such probes and primers hybridize
specifically to a target sequence under high stringency
hybridization conditions.
[0045] Methods for preparing and using probes and primers are
described, for example, in Molecular Cloning: A Laboratory Manual,
2nd ed., vol. 1-3, ed. Sambrook et al., Cold Spring Harbor
Laboratory Press, Cold Spring Harbor, N.Y., 1989 (hereinafter,
"Sambrook et al., 1989"); Current Protocols in Molecular Biology,
ed. Ausubel et al., Greene Publishing and Wiley-Interscience, New
York, 1992 (with periodic updates) (hereinafter, "Ausubel et al.,
1992"); and Innis et al., PCR Protocols: A Guide to Methods and
Applications, Academic Press: San Diego, 1990. PCR-primer pairs can
be derived from a known sequence, for example, by using computer
programs intended for that purpose such as Primer (Version 0.5,
.COPYRGT.1991, Whitehead Institute for Biomedical Research,
Cambridge, Mass.).
[0046] Primers and probes based on the flanking DNA and insert
sequences disclosed herein can be used to confirm the disclosed
sequences by known methods, for example, by re-cloning and
sequencing such sequences.
[0047] The nucleic acid probes and primers of the present invention
hybridize under stringent conditions to a target DNA sequence. Any
nucleic acid hybridization or amplification method can be used to
identify the presence of DNA from a transgenic event in a sample.
Nucleic acid molecules or fragments thereof are capable of
specifically hybridizing to other nucleic acid molecules under
certain circumstances. As used herein, two nucleic acid molecules
are said to be capable of specifically hybridizing to one another
if the two molecules are capable of forming an anti-parallel,
double-stranded nucleic acid structure. A nucleic acid molecule is
said to be the "complement" of another nucleic acid molecule if
they exhibit complete complementarity. As used herein, molecules
are said to exhibit "complete complementarity" when every
nucleotide of one of the molecules is complementary to a nucleotide
of the other. Two molecules are said to be "minimally
complementary" if they can hybridize to one another with sufficient
stability to permit them to remain annealed to one another under at
least "low-stringency" conditions. Similarly, the molecules are
said to be "complementary" if they can hybridize to one another
with sufficient stability to permit them to remain annealed to one
another under "high-stringency" conditions. Stringency conditions
are described by Sambrook et al., 1989, and by Haymes et al., In:
Nucleic Acid Hybridization, A Practical Approach, IRL Press,
Washington, D.C. (1985). Departures from complete complementarity
are therefore permissible, as long as such departures do not
completely preclude the capacity of the molecules to form a
double-stranded structure. In order for a nucleic acid molecule to
serve as a primer or probe it need only be sufficiently
complementary in sequence to be able to form a stable
double-stranded structure under the particular solvent and salt
concentrations employed.
[0048] As used herein, a substantially homologous sequence is a
nucleic acid sequence that will specifically hybridize to the
complement of the nucleic acid sequence to which it is being
compared under high stringency conditions. Appropriate stringency
conditions that promote DNA hybridization, for example, 6.0.times.
sodium chloride/sodium citrate (SSC) at about 45.degree. C.,
followed by a wash of 2.0.times. SSC at 50.degree. C., are known to
those skilled in the art or can be found in Current Protocols in
Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6.
For example, the salt concentration in the wash step can be
selected from a low stringency of about 2.0.times. SSC at
50.degree. C. to a high stringency of about 0.2.times. SSC at
50.degree. C. In addition, the temperature in the wash step can be
increased from low stringency conditions at room temperature, about
22.degree. C., to high stringency conditions at about 65.degree. C.
Both temperature and salt may be varied, or either the temperature
or the salt concentration may be held constant while the other
variable is changed. In one embodiment, a nucleic acid of the
present invention will specifically hybridize to one or more of the
nucleic acid molecules set forth in SEQ ID NO: 1, and SEQ ID NO:
2,or complements or fragments thereof under high stringency
conditions. The hybridization of the probe to the target DNA
molecule can be detected by any number of methods known to those
skilled in the art. These can include, but are not limited to,
fluorescent tags, radioactive tags, antibody based tags, and
chemiluminescent tags.
[0049] Regarding the amplification of a target nucleic acid
sequence (for example, by PCR) using a particular amplification
primer pair, "stringent conditions" are conditions that permit the
primer pair to hybridize only to the target nucleic acid sequence
to which a primer having the corresponding wild-type sequence (or
its complement) would bind and preferably to produce a unique
amplification product, the amplicon, in a DNA amplification
reaction. Examples of DNA amplification methods include PCR,
Recombinase Polymerase Amplification (RPA) (see for example U.S.
Pat No. 7,485,428), Strand Displacement Amplification (SDA) (see
for example, U.S. Pat. Nos. 5,455,166 and 5,470,723),
Transcription-Mediated Amplification (TMA) (see for example,
Guatelli et al., Proc. Natl. Acad. Sci. USA 87:1874-1878 (1990)),
Rolling Circle Amplification (RCA) (see for example, Fire and Xu,
Proc. Natl. Acad Sci. USA 92:4641-4645 (1995); Lui, et al., J. Am.
Chem. Soc. 118:1587-1594 (1996); Lizardi, et al., Nature Genetics
19:225-232 (1998), U.S. Pat. Nos. 5,714,320 and 6,235,502)),
Helicase Dependant Amplification (HDA) (see for example Vincent et
al., EMBO Reports 5(8): 795-800 (2004); U.S. Pat. No. 7,282,328),
and Multiple Displacement Amplification (MDA) (see for example Dean
et. al., Proc. Natl. Acad Sci. USA 99:5261-5266 (2002)).
[0050] The term "specific for (a target sequence)" indicates that a
probe or primer hybridizes under stringent hybridization conditions
only to the target sequence in a sample comprising the target
sequence.
[0051] As used herein, the term "isolated" refers to at least
partially separating a molecule from other molecules normally
associated with it in its native or natural state. In one
embodiment, the term "isolated" refers to a DNA molecule that is at
least partially separated from the nucleic acids that normally
flank the DNA molecule in its native or natural state. Thus, DNA
molecules fused to regulatory or coding sequences with which they
are not normally associated, for example as the result of
recombinant techniques, are considered isolated herein. Such
molecules are considered isolated even when integrated into the
chromosome of a host cell or present in a nucleic acid solution
with other DNA molecules.
[0052] Any number of methods well known to those skilled in the art
can be used to isolate and manipulate a DNA molecule, or fragment
thereof, disclosed in the present invention. For example, PCR
(polymerase chain reaction) technology can be used to amplify a
particular starting DNA molecule and/or to produce variants of the
original molecule. DNA molecules, or fragments thereof, can also be
obtained by other techniques such as by directly synthesizing the
fragment by chemical means, as is commonly practiced by using an
automated oligonucleotide synthesizer.
[0053] The DNA molecules and corresponding nucleotide sequences
provided herein are therefore useful for, among other things,
identifying event KK179-2, selecting plant varieties or hybrids
comprising event KK179-2, detecting the presence of DNA derived
from event KK179-2 in a sample, and monitoring samples for the
presence and/or absence of event KK179-2 or plants and plant parts
comprising event KK179-2.
[0054] The present invention provides plants, progeny, seeds, plant
cells, plant parts such as pollen, ovule, pod, flower, root or stem
tissue, and leaf. These plants, progeny, seeds, plant cells, plant
parts, and commodity products contain a detectable amount of a
polynucleotide of the present invention, such as a polynucleotide
comprising at least one of the sequences provided as the
consecutive nucleotides of SEQ ID NO: 1, and the consecutive
nucleotides of SEQ ID NO: 2. Plants, progeny, seeds, plant cells,
plant parts and commodity products of the present invention may
also contain one or more additional suppression targets.
[0055] The present invention provides plants, progeny, seeds, plant
cells, and plant part such as pollen, ovule, pod, flower, root or
stem tissue, and leaf derived from a transgenic plant comprising
event KK179-2. A representative sample of seed comprising event
KK179-2 has been deposited according to the Budapest Treaty for the
purpose of enabling the present invention. The repository selected
for receiving the deposit is the American Type Culture Collection
(ATCC) having an address at 10801 University Boulevard, Manassas,
Va. USA, Zip Code 20110. The ATCC repository has assigned the
accession No. PTA-11833 to event KK179-2 seed.
[0056] The present invention provides a microorganism comprising a
DNA molecule having a nucleotide sequence selected from the group
consisting of the consecutive nucleotides of SEQ ID NO: 1, the
consecutive nucleotides of SEQ ID NO: 2. An example of such a
microorganism is a transgenic plant cell. Microorganisms, such as a
plant cell of the present invention, are useful in many industrial
applications, including but not limited to: (i) use as research
tool for scientific inquiry or industrial research; (ii) use in
culture for producing endogenous or recombinant carbohydrate,
lipid, nucleic acid, enzymes or protein products or small molecules
that may be used for subsequent scientific research or as
industrial products; and (iii) use with modern plant tissue culture
techniques to produce transgenic plants or plant tissue cultures
that may then be used for agricultural research or production. The
production and use of microorganisms such as trans genic plant
cells utilizes modern microbiological techniques and human
intervention to produce a man-made, unique microorganism. In this
process, recombinant DNA is inserted into a plant cell's genome to
create a transgenic plant cell that is separate and unique from
naturally occurring plant cells. This transgenic plant cell can
then be cultured much like bacteria and yeast cells using modern
microbiology techniques and may exist in an undifferentiated,
unicellular state. The new plant cell's genetic composition and
phenotype is a technical effect created by the integration of the
heterologous DNA into the genome of the cell. Another aspect of the
present invention is a method of using a microorganism of the
present invention. Methods of using microorganisms of the present
invention, such as transgenic plant cells, include (i) methods of
producing transgenic cells by integrating recombinant DNA into
genome of the cell and then using this cell to derive additional
cells possessing the same heterologous DNA; (ii) methods of
culturing cells that contain recombinant DNA using modern
microbiology techniques; (iii) methods of producing and purifying
endogenous or recombinant carbohydrate, lipid, nucleic acid,
enzymes or protein products from cultured cells; and (iv) methods
of using modern plant tissue culture techniques with transgenic
plant cells to produce transgenic plants or transgenic plant tissue
cultures.
[0057] As used herein, "progeny" includes any plant, seed, plant
cell, and/or regenerable plant part comprising the event DNA
derived from an ancestor plant and/or a polynucleotide having at
least one of the sequences provided as the consecutive nucleotides
of SEQ ID NO: 1 or the consecutive nucleotides of SEQ ID NO: 2.
Plants, progeny, and seeds may heterozygous for the presence of the
transgenic sequence. Progeny may be grown from seeds produced by a
plant comprising event KK179-2 and/or from seeds produced by a
plant fertilized with pollen from a plant comprising event
KK179-2.
[0058] Progeny plants may be outcrossed, for example, bred with
another plant, to produce a varietal or a hybrid seed or plant. The
other plant may be transgenic or nontransgenic. A varietal or
hybrid seed or plant of the present invention may thus be derived
by crossing a first parent that lacks the specific and unique DNA
of event KK179-2 with a second parent comprising event KK179-2,
resulting in a hybrid comprising the specific and unique DNA of
event KK179-2. Each parent can be a hybrid or an inbred/variety, so
long as the cross or breeding results in a plant or seed of the
present invention, such as, a seed having at least one allele
comprising the specific and unique DNA of event KK179-2 and/or the
consecutive nucleotides of SEQ ID NO: 1 or SEQ ID NO: 2.
Back-crossing to a parental plant and out-crossing with a
non-transgenic plant are also contemplated, as is vegetative
propagation. Descriptions of other breeding methods that are
commonly used for different traits and crops can be found in one of
several references, for example, Fehr, in Breeding Methods for
Cultivar Development, Wilcox J. ed., American Society of Agronomy,
Madison Wis. (1987).
[0059] Sexually crossing one plant with another plant, such as,
cross-pollinating, may be accomplished or facilitated by human
intervention, for example: by human hands collecting the pollen of
one plant and contacting this pollen with the style or stigma of a
second plant; by human hands and/or human actions removing,
destroying, or covering the stamen or anthers of a plant (for
example, by manual intervention or by application of a chemical
gametocide) so that natural self-pollination is prevented and
cross-pollination would have to take place in order for
fertilization to occur; by human placement of pollinating insects
in a position for "directed pollination" (for example, by placing
beehives in orchards or fields or by caging plants with pollinating
insects); by human opening or removing of parts of the flower to
allow for placement or contact of foreign pollen on the style or
stigma; by selective placement of plants (for example,
intentionally planting plants in pollinating proximity); and/or by
application of chemicals to precipitate flowering or to foster
receptivity (of the stigma for pollen).
[0060] In practicing this method, the step of sexually crossing one
plant with itself, such as, self-pollinating or selfing, may be
accomplished or facilitated by human intervention, for example: by
human hands collecting the pollen of the plant and contacting this
pollen with the style or stigma of the same plant and then
optionally preventing further fertilization of the plant; by human
hands and/or actions removing, destroying, or covering the stamen
or anthers of other nearby plants (for example, by detasseling or
by application of a chemical gametocide) so that natural
cross-pollination is prevented and self-pollination would have to
take place in order for fertilization to occur; by human placement
of pollinating insects in a position for "directed pollination"
(for example, by caging a plant alone with pollinating insects); by
human manipulation of the flower or its parts to allow for
self-pollination; by selective placement of plants (for example,
intentionally planting plants beyond pollinating proximity); and/or
by application of chemicals to precipitate flowering or to foster
receptivity (of the stigma for pollen).
[0061] The present invention provides a plant part that is derived
from a plant comprising event KK179-2. As used herein, a "plant
part" refers to any part of a plant that is comprised of material
derived from a plant comprising event KK179-2. Plant parts include
but are not limited to pollen, ovule, pod, flower, root or stem
tissue, fibers, and leaf. Plant parts may be viable, nonviable,
regenerable, and/or non-regenerable.
[0062] The present invention provides a commodity product that is
derived from a plant comprising event KK179-2. As used herein, a
"commodity product" refers to any composition or product that is
comprised of material derived from a plant, seed, plant cell, or
plant part comprising event KK179-2. Commodity products may be sold
to consumers and may be viable or nonviable. Nonviable commodity
products include but are not limited to nonviable seeds and grains;
processed seeds, seed parts, and plant parts; dehydrated plant
tissue, frozen plant tissue, and processed plant tissue; seeds and
plant parts processed for animal feed for terrestrial and/or
aquatic animal consumption, oil, meal, flour, flakes, bran, fiber,
and any other food for human consumption; and biomasses and fuel
products. Processed alfalfas are the largest source of forage
legume in the world. A plant comprising event KK179-2 can thus be
used to manufacture any commodity product typically acquired from
an alfalfa plant. Any such commodity product that is derived from
the plants comprising event KK179-2 may contain at least a
detectable amount of the specific and unique DNA corresponding to
event KK179-2, and specifically may contain a detectable amount of
a polynucleotide having a nucleotide sequence of the consecutive
nucleotides of SEQ ID NO: 1 and the consecutive nucleotides of SEQ
ID NO: 2. Any standard method of detection for polynucleotide
molecules may be used, including methods of detection disclosed
herein. A commodity product is within the scope of the present
invention if there is any detectable amount of the consecutive
nucleotides of SEQ ID NO: 1 or the consecutive nucleotides of SEQ
ID NO: 2, in the commodity product.
[0063] The plant, progeny, seed, plant cell, plant part (such as
pollen, ovule, pod, flower, root or stem tissue, and leaf), and
commodity products of the present invention are therefore useful
for, among other things, growing plants for the purpose of
producing seed and/or plant parts comprising event KK179-2 for
agricultural purposes, producing progeny comprising event KK179-2
for plant breeding and research purposes, use with microbiological
techniques for industrial and research applications, and sale to
consumers.
[0064] The present invention provides methods for producing plants
with reduced lignin and plants comprising event KK179-2. Event
KK179-2 plant was produced by an Agrobacterium mediated
transformation method similar to that described in U.S. Pat. No.
5,914,451, using an inbred alfalfa line with the construct pFG118.
Construct pFG118 contains a plant suppression cassette for
downregulation of the CCOMT enzyme in alfalfa plant cells.
Transgenic alfalfa cells were regenerated into intact alfalfa
plants and individual plants were selected from the population of
independently transformed transgenic plants that showed desirable
molecular characteristics, such as, the integrity of the transgene
cassette, absence of the construct backbone sequence, loss of the
unlinked kanamycin resistance selection cassette. Furthermore,
inverse PCR and DNA sequence analyses were performed to determine
the 5' and 3' insert-to-plant genome junctions, to confirm the
organization of the elements within the insert (FIG. 1), and to
determine the complete DNA sequence of the insert in alfalfa event
KK179-2 (SEQ ID NO: 5). In addition, transgenic plants were
screened and selected for reduced lignin under field conditions. An
alfalfa plant that contains in its genome the suppression cassette
of pFG118 is an aspect of the present invention.
[0065] Methods for producing a plant with reduced lignin comprising
transgenic event KK179-2 are provided. Transgenic plants used in
these methods may be heterozygous for the transgene. Progeny plants
produced by these methods may be varietal or hybrid plants; may be
grown from seeds produced by a plant and/or from seed comprising
event KK179-2 produced by a plant fertilized with pollen from a
plant comprising event KK179-2; and may be homozygous or
heterozygous for the transgene. Progeny plants may be subsequently
self-pollinated to generate a true breeding line of plants, such
as, plants homozygous for the transgene, or alternatively may be
outcrossed, for example, bred with another unrelated plant, to
produce a varietal or a hybrid seed or plant. As used herein, the
term "zygosity" refers to the similarity of DNA at a specific
chromosomal location (locus) in a plant. In the present invention,
the DNA specifically refers to the trans gene insert along with the
junction sequence (event DNA). A plant is homozygous if the
transgene insert with the junction sequence is present at the same
location on each chromosome of a chromosome pair (4 alleles). A
plant is considered heterozygous if the transgene insert with the
junction sequence is present on only one chromosome of a chromosome
pair (1 allele). A wild-type plant is null for the event DNA.
[0066] Progeny plants and seeds encompassed by these methods and
produced by using these methods are distinct from other plants, for
example, because the progeny plants and seeds are recombinant and
as such created by human intervention; contain at least one allele
that consists of the transgenic DNA of the present invention;
and/or contain a detectable amount of a polynucleotide sequence
selected from the group consisting of consecutive nucleotides of
SEQ ID NO: 1, or consecutive nucleotides of SEQ ID NO: 2. A seed
may be selected from an individual progeny plant, and so long as
the seed comprises SEQ ID NO: 1, or SEQ ID NO: 2, it will be within
the scope of the present invention.
[0067] The plants, progeny, seeds, plant cells, plant parts (such
as pollen, ovule, pod, flower, root or stem tissue, and leaves),
and commodity products of the present invention may be evaluated
for DNA composition, gene expression, and/or protein expression.
Such evaluation may be done by using various methods such as PCR,
sequencing, northern blotting, southern analysis, western blotting,
immuno-precipitation, and ELISA or by using the methods of
detection and/or the detection kits provided herein.
[0068] Methods of detecting the presence of compositions specific
to event KK179-2 in a sample are provided. One method consists of
detecting the presence of DNA specific to and derived from a cell,
a tissue, a seed, a plant or plant parts comprising event KK179-2.
The method provides for a template DNA sample to be contacted with
a primer pair that is capable of producing an amplicon from event
KK179-2 DNA upon being subjected to conditions appropriate for
amplification, particularly an amplicon that comprises SEQ ID NO:
1, and/or SEQ ID NO: 2, or the complements thereof. The amplicon is
produced from a template DNA molecule derived from event KK179-2,
so long as the template DNA molecule incorporates the specific and
unique nucleotide sequences of SEQ ID NO: 1, or SEQ ID NO: 2. The
amplicon may be single or double stranded DNA or RNA, depending on
the polymerase selected for use in the production of the amplicon.
The method provides for detecting the amplicon molecule produced in
any such amplification reaction, and confirming within the sequence
of the amplicon the presence of the nucleotides corresponding to
SEQ ID NO: 1, or SEQ ID NO: 2, or the complements thereof. The
detection of the nucleotides corresponding to SEQ ID NO: 1, and/or
SEQ ID NO: 2, or the complements thereof in the amplicon are
determinative and/or diagnostic for the presence of event KK179-2
specific DNA and thus biological material comprising event KK179-2
in the sample.
[0069] Another method is provided for detecting the presence of a
DNA molecule corresponding to SEQ ID NO: 3 or SEQ ID NO: 4 in a
sample consisting of material derived from plant or plant tissue.
The method consists of (i) obtaining a DNA sample from a plant, or
from a group of different plants, (ii) contacting the DNA sample
with a DNA probe molecule comprising the nucleotides as set forth
in either SEQ ID NO: 1 or SEQ ID NO: 2, (iii) allowing the probe
and the DNA sample to hybridize under stringent hybridization
conditions, and then (iv) detecting a hybridization event between
the probe and the target DNA sample. Detection of the hybrid
composition is diagnostic for the presence of SEQ ID NO: 3 or SEQ
ID NO: 4, as the case may be, in the DNA sample. Absence of
hybridization is alternatively diagnostic of the absence of the
transgenic event in the sample if the appropriate positive controls
are run concurrently. Alternatively, determining that a particular
plant contains either or both of the sequences corresponding to SEQ
ID NO: 1 or SEQ ID NO: 2, or the complements thereof, is
determinative that the plant contains at least one allele
corresponding to event KK179-2.
[0070] It is thus possible to detect the presence of a nucleic acid
molecule of the present invention by any well known nucleic acid
amplification and detection methods such as polymerase chain
reaction (PCR), recombinase polymerase amplification (RPA), or DNA
hybridization using nucleic acid probes. An event-specific PCR
assay is discussed, for example, by Taverniers et al. (J. Agric.
Food Chem., 53: 3041-3052, 2005) in which an event-specific tracing
system for transgenic maize lines Bt11, Bt176, and GA21 and for
transgenic event RT73 is demonstrated. In this study,
event-specific primers and probes were designed based upon the
sequences of the genome/transgene junctions for each event.
Transgenic plant event specific DNA detection methods have also
been described in U.S. Pat. Nos. 7,632, 985; 7,566,817; 7,368,241;
7,306,909; 7,718,373; 7,189,514, 7,807,357 and 7,820,392.
[0071] DNA detection kits are provided. One type of kit contains at
least one DNA molecule of sufficient length of contiguous
nucleotides of SEQ ID NO: 3, SEQ ID NO: 5, or SEQ ID NO: 6 to
function as a DNA primer or probe specific for detecting the
presence of DNA derived from transgenic event KK179-2 in a sample.
The DNA molecule being detected with the kit comprises contiguous
nucleotides of the sequence as set forth in SEQ ID NO: 1.
Alternatively, the kit may contain at least one DNA molecule of
sufficient length of contiguous nucleotides of SEQ ID NO: 4, SEQ ID
NO: 5, or SEQ ID NO: 6 to function as a DNA primer or probe
specific for detecting the presence of DNA derived from transgenic
event KK179-2 in a sample. The DNA molecule being detected with the
kit comprises contiguous nucleotides as set forth in SEQ ID NO:
2.
[0072] An alternative kit employs a method in which the target DNA
sample is contacted with a primer pair as described above, then
performing a nucleic acid amplification reaction sufficient to
produce an amplicon comprising the consecutive nucleotides of SEQ
ID NO: 1, and SEQ ID NO: 2. Detection of the amplicon and
determining the presence of the consecutive nucleotides of SEQ ID
NO: 1, and SEQ ID NO: 2or the complements thereof within the
sequence of the amplicon is diagnostic for the presence of event
KK179-2 specific DNA in a DNA sample.
[0073] A DNA molecule sufficient for use as a DNA probe is provided
that is useful for determining, detecting, or for diagnosing the
presence or even the absence of DNA specific and unique to event
KK179-2 DNA in a sample. The DNA molecule contains the consecutive
nucleotides of SEQ ID NO: 1, or the complement thereof, and the
consecutive nucleotides of SEQ ID NO: 2, or the complement
thereof.
[0074] Nucleic acid amplification can be accomplished by any of the
various nucleic acid amplification methods known in the art,
including thermal and isothermal amplification methods. The
sequence of the heterologous DNA insert, junction sequences, or
flanking sequences from event KK179-2 (with representative seed
samples comprising event KK179-2 deposited as ATCC PTA-11883) can
be verified by amplifying such sequences from the event using
primers derived from the sequences provided herein followed by
standard DNA sequencing of the amplicon or of the cloned DNA.
[0075] The amplicon produced by these methods may be detected by a
plurality of techniques. One such method is Genetic Bit Analysis
(Nikiforov, et al. Nucleic Acid Res. 22:4167-4175, 1994) where a
DNA oligonucleotide is designed which overlaps both the adjacent
flanking genomic DNA sequence and the inserted DNA sequence. The
oligonucleotide is immobilized in wells of a microwell plate.
Following thermal amplification of the region of interest (using
one primer in the inserted sequence and one in the adjacent
flanking genomic sequence), a single-stranded amplicon can be
hybridized to the immobilized oligonucleotide and serve as a
template for a single base extension reaction using a DNA
polymerase and labelled ddNTPs specific for the expected next base.
Readout may be fluorescent or ELISA-based. Detection of a
fluorescent or other signal indicates the presence of the
insert/flanking sequence due to successful amplification,
hybridization, and single base extension.
[0076] Another method is the Pyrosequencing technique as described
by Winge (Innov. Pharma. Tech. 00:18-24, 2000). In this method an
oligonucleotide is designed that overlaps the adjacent genomic DNA
and insert DNA junction. The oligonucleotide is hybridized to a
single-stranded amplicon from the region of interest (one primer in
the inserted sequence and one in the flanking genomic sequence) and
incubated in the presence of a DNA polymerase, ATP, sulfurylase,
luciferase, apyrase, adenosine 5' phosphosulfate and luciferin.
ddNTPs are added individually and the incorporation results in a
light signal which is measured. A light signal indicates the
presence of the trans gene insert/flanking sequence due to
successful amplification, hybridization, and single or multi-base
extension.
[0077] Fluorescence Polarization as described by Chen, et al.,
(Genome Res. 9:492-498, 1999) is a method that can be used to
detect the amplicon. Using this method an oligonucleotide is
designed which overlaps the genomic flanking and inserted DNA
junction. The oligonucleotide is hybridized to single-stranded
amplicon from the region of interest (one primer in the inserted
DNA and one in the flanking genomic DNA sequence) and incubated in
the presence of a DNA polymerase and a fluorescent-labeled ddNTP.
Single base extension results in incorporation of the ddNTP.
Incorporation can be measured as a change in polarization using a
fluorometer. A change in polarization indicates the presence of the
transgene insert/flanking sequence due to successful amplification,
hybridization, and single base extension.
[0078] TAQMAN.RTM. (PE Applied Biosystems, Foster City, Calif.) may
also be used to detect and/or quantifying the presence of a DNA
sequence using the instructions provided by the manufacturer.
Briefly, a FRET oligonucleotide probe is designed which overlaps
the genomic flanking and insert DNA junction. The FRET probe and
amplification primers (one primer in the insert DNA sequence and
one in the flanking genomic sequence) are cycled in the presence of
a thermostable polymerase and dNTPs. Hybridization of the FRET
probe results in cleavage and release of the fluorescent moiety
away from the quenching moiety on the FRET probe. A fluorescent
signal indicates the presence of the flanking/transgene insert
sequence due to successful amplification and hybridization.
[0079] Molecular Beacons have been described for use in sequence
detection as described in Tyangi, et al. (Nature
Biotech.14:303-308, 1996). Briefly, a FRET oligonucleotide probe is
designed that overlaps the flanking genomic and insert DNA
junction. The unique structure of the FRET probe results in it
containing secondary structure that keeps the fluorescent and
quenching moieties in close proximity. The FRET probe and
amplification primers (one primer in the insert DNA sequence and
one in the flanking genomic sequence) are cycled in the presence of
a thermostable polymerase and dNTPs. Following successful
amplification, hybridization of the FRET probe to the target
sequence results in the removal of the probe secondary structure
and spatial separation of the fluorescent and quenching moieties
resulting in the production of a fluorescent signal. The
fluorescent signal indicates the presence of the flanking/transgene
insert sequence due to successful amplification and
hybridization.
[0080] Other described methods, such as, microfluidics (US Patent
Publication No. 2006068398, U.S. Pat. No. 6,544,734) provide
methods and devices to separate and amplify DNA samples. Optical
dyes are used to detect and measure specific DNA molecules
(WO/05017181). Nanotube devices (WO/06024023) that comprise an
electronic sensor for the detection of DNA molecules or nanobeads
that bind specific DNA molecules and can then be detected.
[0081] DNA detection kits can be developed using the compositions
disclosed herein and the methods well known in the art of DNA
detection. The kits are useful for the identification of event
KK179-2 in a sample and can be applied to methods for breeding
plants containing the appropriate event DNA. The kits may contain
DNA primers or probes that are similar or complementary to SEQ ID
NO: 1-6, or fragments or complements thereof.
[0082] The kits and detection methods of the present invention are
therefore useful for, among other things, identifying event
KK179-2, selecting plant varieties or hybrids comprising event
KK179-2, detecting the presence of DNA derived from event KK179-2
in a sample, and monitoring samples for the presence and/or absence
of event KK179-2 or plants, plant parts or commodity products
comprising event KK179-2.
[0083] The following examples are included to demonstrate examples
of certain embodiments of the invention. It should be appreciated
by those of skill in the art that the techniques disclosed in the
examples that follow represent approaches the inventors have found
function well in the practice of the invention, and thus can be
considered to constitute examples of preferred modes for its
practice. However, those of skill in the art should, in light of
the present disclosure, appreciate that many changes can be made in
the specific embodiments that are disclosed and still obtain a like
or similar result without departing from the spirit and scope of
the invention.
EXAMPLES
Example 1: Isolation of Flanking Sequences Using Inverse PCR And
Identification of Flanking Sequences by Sequencing
[0084] This example describes isolation of the alfalfa genomic DNA
sequences flanking the transgenic DNA insert using inverse PCR for
event KK179-2, and identification of the flanking genomic sequences
by sequencing.
[0085] Sequences flanking the T-DNA insertion in event KK179-2 were
determined using inverse PCR as described in Ochman et al., 1990
(PCR Protocols: A guide to Methods and Applications, Academic
Press, Inc.). Plant genomic DNA was isolated from both wild-type
R2336 and the transgenic line from tissue grown under greenhouse
conditions. Frozen leaf tissue was ground with a mortar and a
pestle in liquid nitrogen or by mechanical grinding, followed by
DNA extraction using methods known in the art. This method can be
modified by one skilled in the art to extract DNA from any tissue,
including, but not limited to seed.
[0086] An aliquot of DNA from each sample was digested with
restriction endonucleases selected based on restriction analysis of
the transgenic DNA. After self-ligation of the restriction
fragments, PCR amplification was performed using primers designed
from the transgenic sequence that would amplify sequences extending
away from the 5' and 3' ends of the transgenic DNA. A variety of
Taq polymerases and amplification systems may be used. Table 2
shows an example of PCR amplification for flanking sequence
isolation using Phusion High Fidelity DNA Polymerase (Cat. No. F53
IS or F53 IL, New England Biolabs), and Thermalcyclers Applied
Biosystems GeneAmp 9700, ABI 9800 Fast Thermal Cycler and MJ
Opticon.

[0087] PCR products were separated by agarose gel electrophoresis
and purified using a QIAGEN gel purification kit (Qiagen, Valencia,
Calif.). The subsequent products were sequenced directly using
standard sequencing protocols. Using these two methods, the 5'
flanking sequence, which extends into the left border sequence of
the integrated DNA insert including the CCOMT suppression cassette,
was identified and is presented as SEQ ID NO: 3 ([C] of FIG. 1).
The 3' flanking sequence, which extends into the right border
sequence of the integrated DNA insert including the CCOMT
suppression cassette, was identified and is presented as SEQ ID NO:
4 ([D] of FIG. 1). The transgenic DNA integrated into the 82336
genomic DNA is presented as SEQ ID NO: 5 ([E] of FIG. 1).
[0088] The isolated sequences were compared to the T-DNA sequence
to identify the flanking sequences and the co-isolated T-DNA
fragments. Confirmation of the presence of the expression cassette
was achieved by PCR with primers designed based upon the deduced
flanking sequence data and the known T-DNA sequence. The R2336 wild
type sequence corresponding to the same region in which the T-DNA
was integrated in the transformed line was isolated using primers
designed from the flanking sequences in KK179-2. The flanking
sequences in KK179-2 and the R2336 wild type sequence were analyzed
against multiple nucleotide and protein databases. This information
was used to examine the relationship of the transgene to the plant
genome and to look at the insertion site integrity. The flanking
sequence and wild type sequences were used to design primers for
TAQMAN.RTM. endpoint assays used to identify the events as
described in
Example 2.
Example 2: Event-Specific Endpoint TAQMANO
[0089] This example describes an event-specific endpoint TAQMANO
thermal amplification method for identification of event KK179-2
DNA in a sample.
[0090] Examples of conditions useful with the event
KK179-2-specific endpoint TAQMAN.RTM. method are described in Table
2 and Table 3. The DNA primers used in the endpoint assay are
primers SQ20901 (SEQ ID NO: 7) and SQ23728 (SEQ ID NO: 8) and
6-FAM.TM. labeled oligonucleotide probe PB10164 (SEQ ID NO: 9).
6FAM.TM. is a fluorescent dye product of Applied Biosystems (Foster
City, Calif.) attached to the DNA probe. For TAQMANO.RTM. MGB
(Minor Groove Binding) probes, the 5'exonuclease activity of Taq
DNA polymerase cleaves the probe from the 5'-end, between the
fluorophore and quencher. When hybridized to the target DNA strand,
quencher and fluorophore are separated enough to produce a
fluorescent signal.
[0091] Primers SQ20901 (SEQ ID NO: 7) and SQ23728 (SEQ ID NO: 8)
when used as described with probe PB10164 (SEQ ID NO: 9) produce an
amplicon of 81 nt that is diagnostic for event KK179-2 DNA. The
analysis includes a positive control from alfalfa known to contain
event KK179-2 DNA, a negative control from non-transgenic alfalfa
and a negative control that contains no template DNA.
[0092] These assays are optimized for use with Applied Biosystems
GeneAmp PCR System 9700, ABI 9800 Fast Thermal Cycler and MJ
Research DNA Engine PTC-225. Other methods and apparatus known to
those skilled in the art may be used to produce amplicons that
identify the event KK179-2 DNA.
