Description
[0001] This application claims priority from U.S. Provisional Application
No. 60/685,584, filed May 27, 2005, the entire disclosure of which is
herein incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a new and distinctive transgenic
soybean transformation event, designated MON89788, a soybean cultivar
derived therefrom, and plant parts, seed, and products thereof. The
invention also relates to assays for detecting the presence of a DNA
molecule specific to MON89788 in a plant part extract or seed extract.
[0004] 2. Description of Related Art
[0005] Soybean (Glycine max) is an important crop in many areas of the
world. The methods of biotechnology have been applied to soybean for
improvement of the agronomic traits and the quality of the product. One
such agronomic trait important in soybean production is herbicide
tolerance, in particular, tolerance to glyphosate herbicide. A herbicide
tolerant soybean event would be a useful trait for managing weeds.
[0006] N-phosphonomethylglycine, also known as glyphosate, is a well-known
herbicide that has activity on a broad spectrum of plant species.
Glyphosate is the active ingredient of Roundup.RTM. (Monsanto Co., St.
Louis, Mo.), a safe herbicide having a desirably short half-life in the
environment. When applied to a plant surface, glyphosate moves
systemically through the plant. Glyphosate is phytotoxic due to its
inhibition of the shikimic acid pathway, which provides a precursor for
the synthesis of aromatic amino acids. Glyphosate inhibits the enzyme
5-enolpyruvyl-3-phosphoshikimate synthase (EPSPS) found in plants.
[0007] Glyphosate tolerance can be achieved by the expression of EPSPS
variants that have lower affinity for glyphosate and therefore retain
their catalytic activity in the presence of glyphosate (U.S. Pat. Nos.
5,633,435; 5,094,945; 4,535,060, and 6,040,497). Enzymes that degrade
glyphosate in plant tissues (U.S. Pat. No. 5,463,175) are also capable of
conferring cellular tolerance to glyphosate. Such genes are used for the
production of transgenic crops that are tolerant to glyphosate, thereby
allowing glyphosate to be used for effective weed control with minimal
concern of crop damage. For example, glyphosate tolerance has been
genetically engineered into corn (U.S. Pat. No. 5,554,798), wheat (U.S.
Pat. No. 6,689,880), cotton (U.S. Pat. No. 6,740,488), soybean (WO
9200377) and canola (US Patent Appl. 20040018518). The transgenes for
glyphosate tolerance and the transgenes for tolerance to other
herbicides, e.g. the bar gene, (Toki el al., 1992; Thompson et al., 1987;
phosphinothricin acetyltransferase (DeBlock et al., 1987), for tolerance
to glufosinate herbicide) are also useful as selectable markers or
scorable markers and can provide a useful phenotype for selection of
plants linked with other agronomically useful traits.
[0008] The expression of foreign genes in plants is known to be influenced
by their chromosomal position, perhaps due to chromatin structure (e.g.,
heterochromatin) or the proximity of transcriptional regulation elements
(e.g., enhancers) close to the integration site (Weising et al., 1988).
For this reason, it is often necessary to screen a large number of events
in order to identify an event characterized by optimal expression of an
introduced gene of interest. For example, it has been observed in plants
and in other organisms that there may be a wide variation in levels of
expression of an introduced gene among events. There may also be
differences in spatial or temporal patterns of expression, for example,
differences in the relative expression of a transgene in various plant
tissues, that may not correspond to the patterns expected from
transcriptional regulatory elements present in the introduced gene
construct. For this reason, it is common to produce hundreds to thousands
of different events and screen those events for a single event that has
desired transgene expression levels and patterns for commercial purposes.
An event that has desired levels or patterns of transgene expression is
useful for introgressing the transgene into other genetic backgrounds by
sexual outcrossing using conventional breeding methods. Progeny of such
crosses maintain the transgene expression characteristics of the original
transformant. This strategy is used to ensure reliable gene expression in
a number of varieties that are well adapted to local growing conditions.
[0009] It would be advantageous to be able to detect the presence of a
particular event in order to determine whether progeny of a sexual cross
contain a transgene of interest. In addition, a method for detecting a
particular event would be helpful for complying with regulations
requiring the pre-market approval and labeling of foods derived from
recombinant crop plants, for example. It is possible to detect the
presence of a transgene by any well known polynucleic acid detection
method such as the polymerase chain reaction (PCR) or DNA hybridization
using polynucleic 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 events, particularly those produced
using the same DNA construct unless the sequence of chromosomal DNA
("flanking DNA") adjacent to the inserted transgene DNA is known. An
event-specific PCR assay is discussed, for example, by Windels et al.
(1999), who identified glyphosate tolerant soybean event 40-3-2 by PCR
using a primer set spanning the junction between the insert transgene and
flanking DNA, specifically one primer that included sequence from the
insert and a second primer that included sequence from flanking DNA.
Transgenic plant event specific DNA detection methods have also been to
described in U.S. Pat. Nos. 6,893,826; 6,825,400; 6,740,488; 6,733,974
and 6,689,880; 6,900,014 and 6,818,807, herein incorporated by reference
in their entirety.
[0010] This invention relates to the glyphosate tolerant soybean event
MON89788 (also referred to as MON19788 or GM_A19788) and to the DNA
molecules contained in these soybean plants that are useful in detection
methods for the plant and progeny thereof and plant tissues derived from
MON89788.

genomic DNA from the soybean cell flanking the insertion site soybean
event MON89788. Such junction sequences may, in one aspect of the
invention, be defined as comprising nucleotides 1093-1113 or 5396-5416 of
SEQ ID NO:9, respectively. In other aspects of the invention, the
junctions may be defined as including additional portions of the flanking
genome and transgene, for example, and may be defined as comprising one
or more sequence as given by nucleotides 1073-1113, 1043-1113, 1093-1133,
1093-1163, 1043-1163, 5376-5416, 5346-5416, 5396-5436, 5396-5416,
5396-5466, or 5346-5466 of SEQ ID NO:9. Such sequences and plants and

of SEQ ID NO:3, wherein these nucleic acid molecules when used together
are useful as primers in a DNA amplification method that produces an
amplicon. The amplicon produced using these primers in the DNA
amplification method is diagnostic for soybean event MON89788 DNA. The
amplicon produced by the described primers that is homologous or
complementary to a portion of SEQ ID NO:3 comprising SEQ ID NO:1 is an
aspect of the invention.
[0016] According to another aspect of the invention, two nucleic acid
molecules are provided for use in a DNA detection method, wherein the

amplification reaction produces an amplicon diagnostic for soybean event
MON89788-derived tissue, such as an amplicon that comprises SEQ ID NO:1
or SEQ ID NO:2 or any portion of SEQ ID NO:9 respectively, is another
embodiment of the invention. In a particular embodiment, the primer pair
may consist of primer A (SEQ ID NO:5) and primer D (SEQ ID NO:8).

product derived from a plant or seed comprising event MON89788, in which
the genomic DNA when isolated from the soybean plant, or seed, or product
produces an amplicon in a DNA amplification method that comprises SEQ ID
NO:1 or SEQ ID NO:2.
[0019] Still another aspect of the invention is a soybean plant, or seed,
or product derived from a plant or seed comprising MON89788, in which the
genomic DNA when isolated from the soybean plant, or seed, or product
produces an amplicon in a DNA amplification method, wherein DNA primer
molecules SEQ ID NO:5 and SEQ ID NO:6 are used in the DNA amplification
method.

or SEQ ID NO:2 is a further aspect of the invention.
[0022] According to another aspect of the invention, a method of detecting
the presence of DNA corresponding specifically to the soybean event
MON89788 DNA in a sample is provided. Such method comprising: (a)
contacting a sample comprising DNA with a probe that hybridizes under

DETAILED DESCRIPTION
[0028] The present invention relates to a novel soybean transformation
event designated MON89788 that provides glyphosate tolerance, and the
plant parts and seed and products produced from plants, plant parts,
seed, and products comprising the event. The invention provides DNA
molecules that are novel in the genome of soybean cells comprising
MON89788 and DNA molecules that can be used in various DNA detection
methods to identify MON89788 DNA in a sample. The invention provides a
method to control weeds in a field of plants containing MON89788 by
treating the weeds in the field comprising plants comprising event
MON89788 with a glyphosate herbicide.
[0029] 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. (1991) and Lewin (1994). The
nomenclature for DNA bases as set forth at 37 CFR .sctn.1.822 is used.
[0030] As used herein, the term "soybean" means Glycine max and includes
all plant varieties that can be bred with soybean.
[0031] As used herein, the term "comprising" means "including but not
limited to".
[0032] "Glyphosate" refers to N-phosphonomethylglycine and its salts,
Glyphosate is the active ingredient of Roundup.RTM. herbicide (Monsanto
Co.). Treatments with "glyphosate herbicide" refer to treatments with the
Roundup.RTM., Roundup Ultra.RTM., Roundup Pro.RTM. herbicide or any other
herbicide formulation containing glyphosate. Examples of commercial
formulations of glyphosate include, without restriction, those sold by
Monsanto Company as ROUNDUP.RTM., ROUNDUP.RTM. ULTRA, ROUNDUP.RTM.
ULTRAMAX, ROUNDUP.RTM. CT, ROUNDUP.RTM. EXTRA, ROUNDUP.RTM. BIACTIVE,
ROUNDUP.RTM. BIOFORCE, RODEO.RTM., POLARIS.RTM., SPARK.RTM. and
ACCORD.RTM. herbicides, all of which contain glyphosate as its
isopropylammonium salt; ROUNDUP.RTM. WEATHERMAX (glyphosate potassium
salt), those sold by Monsanto Company as ROUNDUP.RTM. DRY and RIVAL.RTM.
herbicides, which contain glyphosate as its ammonium salt; that sold by
Monsanto Company as ROUNDUP.RTM. GEOFORCE, which contains glyphosate as
its sodium salt; and that sold by Syngenta Crop Protection as
TOUCHDOWN.RTM. herbicide, which contains glyphosate as its
trimethylsulfonium salt. Treatment of a field comprising glyphosate
tolerant soybean plants comprising event MON89788 with any of these
glyphosate herbicide formulations will control weed growth in the field
and not affect the growth or yield of the soybean plants comprising
MON89788.
[0033] A transgenic "event" is produced by transformation of plant cells
with heterologous DNA, for example, a nucleic acid construct that
includes a transgene of interest, regeneration of a population of plants
resulting from the insertion of the transgene into the genome of the
plant, and selection of a particular plant characterized by insertion
into a particular genome location. The term "event" refers to the
original transformant and progeny of the transformant that include the
heterologous DNA. The term "event" also refers to progeny produced by a
sexual outcross between the transformant and another variety that include
the heterologous transgene DNA and the flanking genomic DNA. The term
"event" also refers to DNA from the original transformant comprising the
inserted DNA and flanking genomic sequence immediately adjacent to the
inserted DNA that would be expected to be transferred to a progeny that
receives inserted DNA including the transgene of interest as the result
of a sexual cross of one parental line that includes the inserted DNA
(for example, the original transformant and progeny resulting from the
selling) and a parental line that does not contain the inserted DNA.
[0034] A glyphosate tolerant soybean plant can be bred by first sexually
crossing a first parental soybean plant consisting of a soybean plant
grown from a transgenic glyphosate tolerant soybean plant comprising
MON89788 or an soybean plant that is a progeny of the cross of such a
plant that expresses the glyphosate tolerant phenotype, and a second
parental soybean plant that lacks the tolerance to glyphosate, thereby
producing a plurality of first progeny plants; and then selecting a
progeny plant that is tolerant to application of glyphosate herbicide.
These steps can further include the back-crossing of the glyphosate
tolerant progeny plant to the second parental soybean plant or a third
parental soybean plant, then selecting progeny by application with
glyphosate or by identification with molecular markers associated with
the trait thereby producing an soybean plant that tolerates the
application of glyphosate herbicide. Molecular markers may be used that
comprise the junction DNA molecules identified at the 5' and 3' sites of
insertion of the transgene in event MON89788.
[0035] It is also to be understood that two different transgenic plants
can also be mated to produce offspring that contain two independently
segregating, exogenous transgenes. Back-crossing to a parental plant and
out-crossing with a non-transgenic plant as previously described is 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, e.g., Fehr, (1987).
[0036] A "probe" is an isolated nucleic acid to which is attached a
conventional detectable label or reporter molecule, for example, a
radioactive isotope, a ligand, a chemiluminescent agent, or an 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 a
soybean plant comprising event MON89788 whether from a soybean plant or
seed or from a sample or extract of the plant or seed that includes 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 can
be used to detect the presence of that target DNA sequence.
[0037] "Primers" are isolated polynucleic acids that are annealed to a
complementary target polynucleic acid strand by nucleic acid
hybridization to form a hybrid between the primer and the target
polynucleic acid strand, then extended along the target polynucleic acid
strand by a polymerase, for example, a DNA polymerase. Primer pairs of
the present invention refer to their use for amplification of a target
polynucleic acid molecule, for example, by the polymerase chain reaction
(PCR) or other conventional nucleic acid amplification methods.
[0038] Probes and primers are generally 11 polynucleotides or more in
length, preferably 18 polynucleotides or more, more preferably 24
polynucleotides or 30 polynucleotides or more. Such probes and primers
hybridize specifically to a target molecule under high stringency
hybridization conditions. Preferably, probes and primers according to the
present invention have complete sequence identity with the target
molecule, although probes differing from the target sequence and that
retain the ability to hybridize to target sequences under high stringency
conditions may be designed by conventional methods.
[0039] Methods for preparing and using probes and primers are described,
for example, in Sambrook et al. (1989); Ausubel et al. (1992); and Innis
et al. (1990). PCR-primer pairs (a primer set) 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.).
[0040] Primers and probes based on the flanking genomic DNA and insert
sequences disclosed herein (SEQ ID NOs:1-4 and 9) can be used to confirm
and, if necessary, to correct the disclosed sequences by conventional
methods, for example, by isolating the corresponding DNA molecule from a
deposit of seed comprising MON89788, and determining the nucleic acid
sequence such molecules. Additional associated DNA molecules may be
isolated from the genome of a cell comprising MON89788 that comprise the
transgene insert and genomic flanking regions, and fragments of these
molecules may be used as primers or probes.
[0041] The nucleic acid probes and primers of the present invention
hybridize under stringent conditions to a target DNA sequence. Any
conventional nucleic acid hybridization or amplification method can be
used to identify the presence of DNA from the MON89788 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 and
are of sufficient length to maintain this structure under high stringency
conditions. 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
conventional "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 conventional "high-stringency" conditions. Conventional stringency
conditions are described by Sambrook et al., 1989, and by Haymes et al.
(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.
[0042] 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 which 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 a preferred 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 NOs:1-4,
and 9 complements thereof or fragments of either under moderately
stringent conditions, for example at about 2.0.times.SSC and about
65.degree. C. In a particularly preferred 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 NOs:1-4, and 9 complements
thereof or fragments of either under high stringency conditions. In one
aspect of the present invention, a preferred marker nucleic acid molecule
of the present invention comprises the nucleic acid sequence as set forth
in SEQ ID NO:1 or SEQ ID NO:2 or complements thereof or fragments of
either. In another aspect of the present invention, a preferred marker
nucleic acid molecule of the present invention shares between 80% and
100% or 90% and 100% sequence identity with the nucleic acid sequence set
forth in SEQ ID NO:1 or SEQ ID NO:2 or complements thereof or fragments
of either. Molecular marker DNA molecules that comprise SEQ ID NO:1, or
SEQ ID NO:2, or complements thereof or fragments of either may be used as
markers in plant breeding methods to identify the progeny of genetic
crosses similar to the methods described for simple sequence repeat DNA
marker analysis, in Cregan et al. (1997); all of which is herein
incorporated by reference in its' entirely. 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.
[0043] 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 thermal amplification reaction.
[0044] 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.
[0045] As used herein, "amplified DNA" or "amplicon" refers to the product
of nucleic acid amplification of a target nucleic acid sequence that is
part of a nucleic acid template. For example, to determine whether the
soybean plant resulting from a sexual cross contains transgenic event
MON89788 or whether a soybean sample collected from a field comprises
MON89788, or a soybean extract, such as a meal, flour or oil comprises
MON89788. DNA extracted from a soybean plant tissue sample or extract may
be subjected to a nucleic acid amplification method using a primer pair
that includes a primer derived from the genomic region adjacent to the
insertion site of inserted heterologous transgene DNA, and a second
primer derived from the inserted heterologous transgene DNA to produce an
amplicon that is diagnostic for the presence of the event DNA. The
amplicon is of a length and has a sequence that is also diagnostic for
the event. The amplicon may range in length from the combined length of
the primer pairs plus one nucleotide base pair, or plus about fifty
nucleotide base pairs, or plus about two hundred-fifty nucleotide base
pairs, or plus about three hundred-fifty nucleotide base pairs or more.
[0046] Alternatively, a primer pair can be derived from flanking genomic
sequence on both sides of the inserted DNA so as to produce an amplicon
that includes the entire insert nucleotide sequence. A member of a primer
pair derived from the plant genomic sequence may be located a distance
from the inserted transgene DNA molecule, this distance can range from
one nucleotide base pair up to about twenty thousand nucleotide base
pairs. The use of the term "amplicon" specifically excludes primer dimers
that may be formed in the DNA thermal amplification reaction.
[0047] Nucleic acid amplification can be accomplished by any of the
various nucleic acid amplification reaction methods known in the art,
including the polymerase chain reaction (PCR). A variety of amplification
methods are known in the art and are described, inter alia, in U.S. Pat.
Nos. 4,683,195 and 4,683,202 and in Innis et al. (1990). PCR
amplification methods have been developed to amplify up to 22 kb of
genomic DNA and up to 42 kb of bacteriophage DNA (Cheng et al., 1994).
These methods as well as other methods known in the art of DNA
amplification may be used in the practice of the present invention. The
sequence of the heterologous DNA insert or flanking sequence from soybean
event MON89788 and can be verified, and corrected if necessary by
amplifying such molecules from the event genome using primers derived
from the sequences provided herein followed by standard DNA sequencing
methods applied to the PCR amplicon or to isolated cloned
transgene/genomic DNA.
[0048] The amplicon produced by these methods may be detected by a
plurality of techniques. One such method is Genetic Bit Analysis
(Nikiforov, et al., 1994) where an DNA oligonucleotide is designed which
overlaps both the adjacent flanking genomic DNA sequence and the inserted
DNA transgene sequence. The oligonucleotide is immobilized in wells of a
microwell plate. Following PCR of the region of interest (using one
primer in the inserted sequence and one in the adjacent flanking genomic
sequence), a single-stranded PCR product 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. A
signal indicates presence of the insert/flanking genomic sequence due to
successful amplification, hybridization, and single base extension.
[0049] Another method is the Pyrosequencing technique as described by
Winge (2000). In this method an oligonucleotide is designed that overlaps
the adjacent genomic DNA and insert DNA junction. The oligonucleotide is
hybridized to single-stranded PCR product 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. DNTPs are added individually and the incorporation results in
a light signal which is measured. A light signal indicates the presence
of the transgene insert/flanking sequence due to successful
amplification, hybridization, and single or multi-base extension.
[0050] Fluorescence Polarization as described by Chen et al. (1999) is a
method that can be used to detect the amplicon of the present invention.
Using this method an oligonucleotide is designed which overlaps the
genomic flanking and inserted DNA junction. The oligonucleotide is
hybridized to single-stranded PCR product 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 genomic sequence due to successful
amplification, hybridization, and single base extension.
[0051] Taqman.RTM. (PE Applied Biosystems, Foster City, Calif.) is
described as a method of detecting and quantifying the presence of a DNA
sequence and is fully understood in 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
PCR 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 genomic/transgene insert sequence due to successful
amplification and hybridization.
[0052] Molecular Beacons have been described for use in sequence detection
as described in Tyangi et al. (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 PCR 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 PCR
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. A fluorescent
signal results. A fluorescent signal indicates the presence of the
flanking genomic/transgene insert sequence due to successful
amplification and hybridization.
[0053] Other described methods, such as, microfluidics (US Patent Pub.
2006068398, U.S. Pat. No. 6,544,734) provide methods and devices to
separate and amplify DNA samples. Optical dyes used to detect and
quantitate 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 are useful for detecting DNA molecules of the present invention.
[0054] DNA detection kits can be developed using the compositions
disclosed herein and the methods described or known in the art of DNA
detection. The kits are useful for the identification of soybean event
DNA in a sample and can be applied to methods for breeding soybean plants
containing DNA. The kits may contain DNA primers or probes that are
homologous or complementary to SEQ ID NOs:1-4 and 9 or DNA primers or
probes homologous or complementary to DNA contained in the transgene
genetic elements of DNA, these DNA sequences can be used in DNA
amplification reactions or as probes in a DNA hybridization method. The
structure of the DNA of the transgene genetic elements contained in the
soybean genome and illustrated in FIG. 1 comprises a 5' genomic region of
the soybean A3244 genome flanking the transgene insert, the insert
comprising a portion of the right border region (RB) from Agrobacterium
tumefaciens, the chimeric promoter FMV/Tsf1 and related linked elements
(U.S. Pat. No. 6,660,911; also referred to as FMV/E1F1.alpha.) is
operably connected to an Arabidopsis EPSPS chloroplast transit peptide
coding sequence (herein referred to as CTP2 or TS-AtEPSPS CTP2, U.S. Pat.
No. 5,633,435, operably connected to a glyphosate resistant EPSPS (herein
referred to as CP4 EPSPS or aroA:CP4, isolated from Agrobacterium
tumefaciens strain CP4 and coding sequence modified for enhanced
expression in plant cells, U.S. Pat. No. 5,633,435), operably connected
to the 3' termination, region from pea ribulose 1,5-bisphosphate
carboxylase (herein referred to as E9 3' or T-Ps.RbcS:E9, Coruzzi et al.,
(1984), a portion of the left border (LB) region from Agrobacterium
tumefaciens, and the 3' genomic region of the soybean A3244 genome
flanking the transgene insert. DNA molecules useful as primers in DNA
amplification methods can be derived from the sequences of the genetic
elements of the transgene insert contained in soybean event MON89788.
These primer molecules can be used as part of a primer set that also
includes a DNA primer molecule derived from the genome of soybean
flanking the transgene insert. Soybean event MON89788 was produced by
transformation of soybean line A3244 (U.S. Pat. No. 5,659,114) by an
Agrobacterium mediated method, for example, methods described in U.S.
Pat. Nos. 6,384,301 and 7,002,058 (herein incorporated by reference in
their entirety).
[0055] The inventors of the present invention have discovered that a
soybean line comprising the MON89788 T-type genomic region (T-type is
combination of a transgene and the associated haplotype region of a plant
genome) in its genome has an improved yield relative to a line comprising
the previous 40-3-2 T-type genomic region. This was demonstrated in
replicated field trials including yield data collected from multiple
locations in the United States (U.S. patent application 60/685,584).
[0056] The following examples are included to demonstrate examples of
certain preferred 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
Production of Amplicon Diagnostic for MON89788 Genomic DNA
[0057] DNA from transgenic soybean event MON89788 is extracted from tissue
comprising soybean seeds, vegetative tissue, or meal. The DNA is isolated
from the tissue using Qiagen's DNeasy Plant Miniprep Kit according to the
manufacturer's instructions (Qiagen Corp. Valencia, Calif.).
[0058] A PCR product is produced that comprises a portion of the genomic
DNA flanking the 5' end of the T-DNA (transfer DNA comprising the
transgene) insertion in the genome of a plant comprising MON89788. This
DNA product comprises SEQ ID NO:3. The PCR may be performed using one
primer designed to hybridize to the genomic DNA sequences flanking the 5'
end of the transgene insert (DNA primer A, SEQ ID NO:5; see FIG. 1)
paired with a second primer (DNA primer B, SEQ ID NO:6) located in the
transgene promoter region (U.S. Pat. No. 6,660,911, SEQ ID NO:28, herein
incorporated by reference and found within SEQ ID NO:9).
[0059] A PCR product is produced from the 3' end of the transgene insert
that comprises a portion of the genomic DNA flanking the 3' end of the
T-DNA insertion in the genome of a plant comprising MON89788 This DNA
product comprises SEQ ID NO:4. PCR may be performed using one primer
designed to hybridize to the genomic DNA sequences flanking the 3' end of
the insert of each event (DNA primer D, SEQ ID NO:8) and paired with a
second primer (DNA primer C, SEQ ID NO:7) located in the T-Ps.RbcS:E9 3'
transcription termination sequence at the 3' end of the insert.
[0060] The PCR template includes .about.50 ng of genomic DNA. As a
negative control .about.50 ng of genomic DNA from the non-transgenic
soybean cultivar is utilized. Each PCR reaction contains 5 .mu.l
10.times. Buffer for REDAccuTaq.TM. LA DNA Polymerase Mix (Sigma-Aldrich,
St Louis, Mo.), 200 .mu.M each dNTP (Sigma-Aldrich), 0.4 .mu.M each
primer, and 2.5 Units JumpStart.TM. REDTaq.TM. DNA Polymerase
(Sigma-Aldrich) in a 50 .mu.l total volume reaction. The PCR reactions
are performed under the following cycling conditions: 1 cycle at
94.degree. C. for 3 minutes (min); 32 or 35 cycles at 94.degree. C. for
30 seconds (s), 58.degree. C. for 30 s, 72.degree. C. for 30 s or 1 min;
1 cycle at 72.degree. C. for 10 min.
[0061] DNA event primer pairs are used to produce an amplicon diagnostic
for MON89788 genomic DNA. These event primer pairs include, but are not
limited to primers A and B (SEQ ID NO:5 and 6) and event primer pairs C
and D (SEQ ID NO: 7 and 8), that are used in the described DNA
amplification method. In addition to these primer pairs, any primer pair
derived from SEQ ID NO:3 or SEQ ID NO:4, or the complements thereof, that
when used in a DNA amplification reaction produces an amplicon that
comprises SEQ ID NO:1 or SEQ ID NO:2 diagnostic for soybean MON89788
event-derived tissue, respectively, may be utilized. DNA amplification
conditions illustrated in Table 1 and Table 2 can be used to produce a
diagnostic amplicon for MON89788 using the appropriate event primer
pairs. Any modification of these methods used to produce an amplicon
diagnostic for MON89788 is within the ordinary skill of the art. An
extract putatively containing DNA of a soybean plant or seed comprising
MON89788, or a product derived from a plant comprising MON89788 that when
tested in a DNA amplification method produces an amplicon diagnostic for
soybean event MON89788 may be utilized as a template for amplification to
determine whether MON89788 is present.
[0062] The amplicon is produced by the use of at least one primer sequence
derived from SEQ ID NO:3 or SEQ ID NO:4 that when used in a PCR method
produces a diagnostic amplicon for event MON89788. For example, the
production of the MON89788 amplicons can be performed using a Stratagene
Robocycler, MJ Engine, Perkin-Elmer 9700, or Eppendorf Mastercycler
Gradient thermocycler as shown in Table 2, or by methods and apparatus
known to those skilled in the art.

Sequence Determination of Transgene/Genomic Region and Southern Analysis
[0064] DNA sequencing of the PCR products provides for DNA that can be
used to design additional DNA molecules as primers and probes for the
identification of soybean plants or seed comprising MON89788. PCR
products of the expected sizes representing the 5' and 3'
transgene/genomic sequences were isolated by separation of the PCR
products on a 2.0% agarose gel by electrophoresis. PCR products are
isolated that include the 5' and 3' DNA regions that span the insert
junction between the transgene insertion into the soybean genome. The 5'
and 3' PCR products for MON89788 are purified by agarose gel
electrophoresis followed by isolation from the agarose matrix using the
QIAquick Gel Extraction Kit (catalog #28704, Qiagen Inc., Valencia,
Calif.). The purified PCR products are then sequenced (e.g. ABI Prism.TM.
377, PE Biosystems, Foster City, Calif.) and analyzed (e.g. DNASTAR
sequence analysis software, DNASTAR Inc., Madison, Wis.).
[0065] A DNA sequence was determined for the nucleotide base pair segment
representing the transgene/genomic region of event MON89788 as
illustrated in FIG. 1 and identified as SEQ ID NO:9. The genomic and
transgene elements that are contained in SEQ ID NO:9 are described in
Table 3. The 5' and 3' flanking regions are included in SEQ ID NO:9 and
given in SEQ ID NOs:21 and 22.
[0066] The junction sequences are relatively short polynucleotide
molecules that are novel DNA sequences and are diagnostic for MON89788
DNA when detected in a polynucleic acid detection assay. The junction
sequences in SEQ ID NO:1 and SEQ ID NO:2 represent 10 polynucleotides on
each side of an insertion site of the transgene fragment and soybean
genomic DNA in MON89788. Longer or shorter polynucleotide junction
sequences can be selected from SEQ ID NO:3 or SEQ ID NO:4. The junction
molecules (5'junction region SEQ ID NO:1, and 3' junction region SEQ ID
NO:2) are useful as DNA probes or as DNA primer molecules in methods for
DNA detection.
[0067] Primers and probes used in a Taqman.RTM. method (Roche Molecular
Systems, Inc., Pleasanton, Calif.) for detection of an event specific DNA
molecule were developed for event MON89788. The primer molecules are
referred to as SQ2824 (SEQ ID NO:10), SQ2826 (SEQ ID NO:11), SQ1141 (SEQ
ID NO:12), SQ1142 (SEQ ID NO:13), SQ5543 (SEQ ID NO:14) and the probe
molecules are referred to as PB871-6FAM (SEQ ID NO:15), PB2191-VIC (SEQ
ID NO:16), and PB57-VIC (SEQ ID NO:17). The primers and probes were used
in the Taqman.RTM. method according to manufacturers instructions to
provide a diagnostic amplicon for DNA comprising MON89788. Soybean
tissues including processed products, for example meal, are useful
sources of DNA for this method. Additional primers used to produce an
amplicon from soymeal include SEQ ID NOs:18-20.

Southern Blot Analysis
[0068] Genomic DNA from a plant comprising MON89788 and control soybean
genomic DNA (.about.15 .mu.g of each) is digested with various
restriction enzymes (140 U) in a total volume of 150 .mu.l including 15
.mu.l of the corresponding manufacturer's buffer (NEB, Beverly, Mass.).
Restriction endonucleases, e.g., Bgl11, BamH1, Nco1, Hind111, and Bcl1,
are used in the Southern analysis of MON89788. Endonuclease digests are
performed at the appropriate temperature for at least 6 hours. After
incubating, the DNA is precipitated with 3M sodium acetate and 2.5
volumes of ethanol. Subsequently, the DNA is washed with 70% ethanol,
dried, and resuspended in 40 .mu.l of TBE. Loading buffer (0.2.times.) is
added to the samples and then subjected to electrophoresis on agarose
gels (0.8%) for 16-18 hours at 30 volts. The gels are stained with
ethidium-bromide, then treated with a depurination solution (0.125N HCL)
for 10 minutes, with a denaturing solution (0.5M sodium hydroxide, 1.5M
sodium chloride) for 30 minutes, and finally with a neutralizing solution
(0.5M Trizma base, 1.5M sodium chloride) for 30 minutes. The DNA is
transferred to Hybond-N membrane (Amersham Pharmacia Biotech,
Buckingamshire, England) using a Turboblotter (Schleicher and Schuell,
Dassel, Germany) for 4-6 hours and then fixed to the membrane using a UV
light.
[0069] Membranes are prehybridized with 20 mls of DIG Easy Hyb solution
(Roche Molecular Biochemicals, Indianapolis, Ind.; cat. #1603558) for 2-4
hours at 45.degree. C. Radioactive DNA probes (.sup.32P dCTP) homologous
or complementary to SEQ ID NO:1, or SEQ ID NO:2, or SEQ ID NO:3, or SEQ
ID NO:4, or a portion thereof are made using a Radprime DNA Labeling kit
(Invitrogen, Carlsbad, Calif.; cat. #18428-011). Unincorporated
nucleotides are removed using SEPHADEX G-50 columns (Invitrogen). The
prehybridization solution is replaced with 10 mls of pre-warmed DIG Easy
Hyb solution containing the denatured probe to a final concentration of 1
million counts per ml. The blots are hybridized at 45.degree. C. for
16-18 hours.
[0070] Blots are washed with a low stringency solution (5.times.SSC,
0.1.times.SDS) at 45.degree. C. and then repeatedly washed with a higher
stringency solution (0.1.times.SSC, 0.1% SDS) at 65.degree. C. The blots
are exposed to a phosphor screen (Amersham Biosciences, Piscataway, N.J.)
for >2 hours and the exposure read using a Data Storm 860 machine
(Amersham Biosciences). These methods and conditions exemplified may be
modified by those skilled in the art of detecting DNA in a sample.
Example 3
Weed Control
[0071] Controlling the growth of weeds in a field of soybeans comprising
MON89788. A field is planted with soybean seeds comprising MON89788, the
seeds are allowed to germinate into plants and the field of plants is
treated with a herbicide formulation containing glyphosate. An effective
dose of a glyphosate formulation at treatment rates of from about 0.25 lb
ae/A (pounds of glyphosate acid equivalent/acre) to 3 or more lb ae/A is
applied to the field. Rates often applied range from about 0.75 lb ae/A
to 1.5 lb ae/A at a frequency of one or more treatments during the
growing season as necessary to control the growth of weeds in a field.
Seeds from the plants comprising MON89788 are harvested from the treated
plants.
[0072] A deposit of the Monsanto Technology LLC, soybean seed
representative of event MON89788 disclosed above and recited in the
claims has been made under the Budapest Treaty with the American Type
Culture Collection (ATCC), 10801 University Boulevard, Manassas, Va.
20110. The ATCC accession number for the deposit comprising event
MON89788 (also known as MON19788 or GM_A19788) is PTA-6708, deposited May
11, 2005. The deposit will be maintained in the depository for a period
of 30 years, or 5 years after the last request, or for the effective life
of the patent, whichever is longer, and will be replaced as necessary
during that period.
[0073] Having illustrated and described the principles of the present
invention, it should be apparent to persons skilled in the art that the
invention can be modified in arrangement and detail without departing
from such principles. We claim all modifications that are within the
spirit and scope of the appended claims.
