Embodiments for Carrying Out the Invention

[0006] It should be noted that the present invention is not limited to the specific methods, protocols, and reagents described herein and may vary accordingly. The terms used herein are for the purpose of describing only specific embodiments and are not intended to limit the scope of the present invention, which is defined only by the claims.

[0007] All patents or other publications are hereby incorporated by reference into this specification for the purpose of, for example, explaining and disclosing the methods described in such publications that may be used in connection with the present invention, but are not to be construed as providing definitions of terms that are inconsistent with the definitions presented herein. Such publications are provided only for the purpose of disclosing prior to the filing date of this application. In this regard, nothing should be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention or for any other reason. All statements as to the date or content of such documents are based on the information available to the applicant and do not constitute an admission as to the accuracy of the date or content of such documents.

[0008] As used in this specification and the claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. Throughout this specification, unless otherwise specified, the terms "comprise", "comprises", and "comprising" are used in a non-exclusive and inclusive sense, such that the recited integer or group of integers may include one or more other unrecited integers or groups of integers. The term "or" is inclusive, unless modified, for example, by "either". Thus, unless the context otherwise dictates, the word "or" means any one member of a particular list and also includes any combination of members of that list.

[0009] All values are approximate because there is some variation due to environmental conditions in the fatty acid compositions. Values are generally expressed as area percentages, which approximate the weight percentages of the total fatty acids, or of the total seeds. Thus, unless otherwise indicated in an example or otherwise specified, all numbers expressing amounts or reaction conditions used in this specification are to be understood as being modified in all instances by the term "about".

[0010] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art. The terms used in this specification are for the purpose of describing particular embodiments only and are not intended to limit the scope of the invention, which is defined only by the claims. To better understand the present disclosure, certain terms are first defined. Further definitions are set forth throughout the detailed description.

[0011] This embodiment provides a Brassica line that produces LC ω3 PUFA DPA in its seed oil, and in particular, provides a line that embodies the characteristics of the B. juncea line NUBJ1207. LC ω3 PUFAs are known in the art by appropriate discussion thereof and for other fatty acids; see, for example, U.S. Patent No. 10,570,405.

[0012] Brassica juncea belongs to the Brassicaceae (Cruciferae) plant family, commonly known as the mustard family. Generally, B. juncea has light green leaves with a few hairs on the first leaf and the leaf blade that remains on the petiole. The plant reaches a height of 1-2 meters, has deep lobes on the lower leaves, and the upper leaves are narrow and open overall and do not close. The flowers are pale yellow and open gradually upward from the bottom of the slender raceme. The silique (seed pod) is slightly adherent and is 2.5-5 cm long excluding the beak, which is 0.5-1 cm long, and the seeds are round and may be yellow or brown. B. juncea is an amphidiploid (AABB genome, 2n = 36) of B. rapa (AA genome, 2n = 20) by B. nigra (BB genome, 2n = 16).

[0013] Brassica juncea ssp. juncea is cultivated mainly for its seeds. More specifically, the oilseed B. juncea is grown as a spice crop (mustard seed) in North America, but is also used as a source of cooking oil in Asia and other regions. Almost all of the oilseed B. juncea grown (mostly in the Indian subcontinent) has high levels of both erucic acid and glucosinolates, but there are low glucosinolate and low erucic acid subspecies that provide canola-quality edible oil. More specifically, "canola oil" is defined as having less than 2% erucic acid, and canola meal is defined as non-oil meal, air-dried to 1 gram, containing less than 30 μmol of 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3-butenyl glucosinolate, 2-hydroxy-4-pentenyl glucosinolate, or mixtures thereof. See, for example, CODEX ALIMENTARIUS: FATS, OILS & RELATED PRODUCTS, Vol. 8 (2nd Ed., Food & Agriculture Org. United Nations, Rome, Italy, 2001). In particular, the erucic acid content of the seed oil of the B. juncea line NUBJ1207 is less than 1%.

[0014] Compared to canola species B. napus and B. rapa, which are grown over a wider range, B. juncea is more resistant to heat and drought stress. Typically, B. juncea is more resistant to crushing than some B. napus, and can be either banded or linear in combination. Further information on the ecology, hybridization, and diseases of B. juncea is readily available. See, for example, Canadian Food Inspection Agency, Biology Document BIO2007-01, Biology of Brassica juncea (Canola / Mustard) (2012). Neither wild-type B. juncea, B. napus, nor B. rapa produces DPA in seed oil.

[0015] A "line" is a group of plants that shows little overall variation among individuals sharing that designation. A "line" also refers to a homogeneous population of plants having substantially the same genetic material, which shows little or no genetic variation among individuals, particularly with respect to at least one trait and in the transgenes present in line NUBJ1207 and the resulting DPA product. The terms "subspecies" or "cultivar" may be used interchangeably with "line", although generally the former two terms refer to lines suitable for commercial production. For example, "derived genetically", as used in the phrase "derived genetically from the parental line", means that the characteristic in question is indicated in whole or in part by some aspect of the genetic constitution of the plant in question.

[0016] "Progeny" means all descendants, including the offspring and derivatives of a plant, and includes the first, second, third, and subsequent generations, and may be produced by self-pollination of the plant or by crossing with plants having the same or different genotypes, and may be modified by various suitable genetic engineering techniques. The cultivated variety is usually related to a plant intentionally altered and selected by humans. "T0" refers to the first generation of transformed plant material, "T1" refers to the seeds produced on the T0 plant, and the T1 seeds give rise to plants that produce T2 seeds, etc. for subsequent Tx progeny.

[0017] "A part of a plant" includes plant cells, plant organs, plant protoplasts, plant cell tissue cultures from which plants can be redifferentiated, plant callus, plant aggregates, and intact plant cells in plants or parts thereof such as embryos, pollen, ovules, seeds, sheaths, leaves, flowers, branches, fruits, stalks, roots, root tips, anthers, cotyledons, hypocotyls, radicles, single cells, propagules, cell cultures, tissue cultures, etc. Cotyledons are a type of seed leaf and small leaves are contained on the plant embryo. Cotyledons contain the food storage tissue of the seed. An embryo is a small plant contained within a mature seed. "Plant cell" also encompasses non-redifferentiable plant cells. The progeny, derivatives, variants, and mutants of redifferentiated plants are also within the scope of this embodiment if some of them contain one, two, or three of the nucleic acid molecules as exemplified by SEQ ID NOs: 1 and 2, SEQ ID NOs: 3 and 4, and SEQ ID NOs: 5 and 6, and the molecules have the characteristics of DPA JUNCEA NUBJ1207. This embodiment also relates to the use of the elite event NUBJ1207 transgene in plant cell cultures and tissue cultures. This embodiment includes plants and parts of plants from the elite event NUBJ1207 line, as well as other plants produced by the described methods.

[0018] At least one embodiment described herein provides a novel B. juncea line, designated NUBJ1207, which produces DPA in its seed oil. Other aspects of this embodiment include the seeds, plants, and parts of plants of DPA juncea NUBJ1207, and methods for producing canola plants produced by crossing DPA juncea NUBJ1207 with itself or with other canola genotypes, and the generation of mutants by mutagenesis or transformation of DPA juncea NUBJ1207. Thus, this embodiment includes any method of using line NUBJ1207, examples of which include selfing, backcrossing, hybrid production, and crossing into a population. All plants produced using line NUBJ1207 as a parent are within the scope of this embodiment. In at least one embodiment, the DPA juncea line NUBJ1207 is used in crosses with other different canola plants to produce seeds and plants of first-generation (F 1 ) hybrids having excellent characteristics. Thus, examples of members of the genus Brassica useful in practicing this embodiment include, in addition to B. juncea, B. napus, B. napobrassica, B. oleracea, B. carinata, B. rapa, and B. campestris, and any other plant belonging to the genus Brassica that enables breeding between Brassica species. Typically, an "oilseed plant" refers to any one of the species of B. napus, B. rapa (or campestris), or B. juncea.

[0019] The phenotypic characterization of the DPA juncea line NUBJ1207 includes, in addition to the production of DPA in the seed oil, the following.

[0020]

Table 1

[0021] The DPA juncea described in this specification may be of A line, B line, or R line. The A line is a male sterile line, B is similar to "A" in all characteristics but is a male fertile line, and R, when crossed with the B line, restores fertility in the F1 hybrid. The B line is sometimes called the maintenance line because it is used to maintain fertility. The restoring line is a pollinating subspecies that is used to pollinate a male sterile line to produce F1 progeny that are male fertile and can self-propagate to produce seeds. Inbred lines may enable the restoration of fertility to the progeny of the male sterile line with which they are crossed. Thus, the hybrid line may be grown from F1 seeds produced by crossing two inbred (pure line) lines, one of which may be male sterile.

[0022] For pure line selection, the progeny (self-pollination) by single plant selection are maintained separately and are not bulked together. A set of genetically homogeneous lines is the expected result. Thus, a pure line may be the progeny of a homozygous plant by single self-fertilization.

[0023] Accordingly, the present embodiment provides a method for introducing desirable traits into the DPA juncea line NUBJ1207, where the method comprises crossing a NUBJ1207 plant with a plant of another Brassica genotype comprising the desirable trait for generating progeny plants, where the desirable trait is selected from the group consisting of male sterility, herbicide tolerance, pest tolerance, modified fatty acid metabolism, modified carbohydrate metabolism, modified seed yield, modified oil percentage, modified protein percentage, modified lodging resistance, and resistance to bacterial, fungal, or viral diseases; selecting one or more progeny plants having the desirable trait for generating selected progeny plants; crossing the selected progeny plants with a NUBJ1207 plant for generating progeny plants by backcrossing; selecting progeny plants by backcrossing having substantially all of the desirable traits of the NUBJ1207 line, as well as physiological and morphological characteristics; and repeating these steps three or more times for generating selected fourth and subsequent generation progeny plants by backcrossing, comprising substantially all of the desirable traits of the NUBJ1207 line, as well as physiological and morphological characteristics. Plants produced by this method are included in this aspect of the embodiment, where the plants have substantially all of the desirable traits (i.e., DPA production) of the NUBJ1207 line, as well as physiological and morphological characteristics.

[0024] "Breeding" includes all methods of growing or propagating plants and includes all suitable conventional breeding techniques and artificial breeding techniques, in addition to crossing both interspecies and intraspecies and interline and intra-line. Desirable traits (e.g., the DPA trait of NUBJ1207) may be transferred to other canola lines or B. juncea lines, cultivars, or accessions, or may be transferred through conventional breeding methods, or may be transferred to other Brassica species such as B. napus and B. rapa through interspecies crossing. Both conventional breeding methods and interspecies crossing methods, as well as other methods of transferring genetic material between plants, are well known in the art.

[0025] B. juncea line NUBJ1207 was developed by Agrobacterium tumefaciens-mediated transformation with the gene construct pJP3416_GA7-modB (“modB”) and contains seven genes that can promote the accumulation of omega-3 fatty acids in seeds. Briefly, the modB construct contains genes encoding a Δ6 desaturase cloned from the microalga Micromonas pusilla, a Δ6-elongase and a Δ5 elongase cloned from the microalga Pyramimonas cordata, a Δ5 desaturase cloned from the microalga Pavlova salina, a Δ15 / ω3-desaturase cloned from the yeast Pichia pastoris, a Δ12 desaturase cloned from the yeast Lachancea kluyveri, and a Δ4 desaturase cloned from Pavlova salina, each having an appropriate transcriptional promoter and terminator. See, for example, U.S. Patent Nos. 10,570,405 (FIG. 1), 10,563,218, 10,125,084, 9,718,759, 9,932,541. However, upon insertion into B. juncea (low erucic acid, low glucosinolate line) from which NUBJ1207 is derived, the Δ4-desaturase gene of modB was truncated and rendered non-functional.

[0026] Genetic analysis revealed that NUBJ1207 contains the loci of three recombinant transgenes, each of which has a separate transgene insert containing an expression cassette, and each insert is located in a different chromosome. In particular, the transgene insert in chromosome A06 of NUBJ1207 contains a truncated MAR sequence (640 bp Rb7 matrix attachment region of Nicotiana tabacum), a promoter of Arabidopsis thaliana FA elongase 1 (Pro_Arath-FAE1), the P. cordata Δ6-elongase gene, a terminator of Glycine max lectin (Ter_Glyma-Lectin), a promoter of cauliflower mosaic virus 35S RNA, a coding sequence of phosphinothricin acetyltransferase (PAT) enzyme, a terminator from A. tumefaciens nopaline synthase (TER_Agrtu-NOS), and a left border sequence (LB) of A. tumefaciens used for T-DNA transcription. The transgene insert in chromosome B07 of NUBJ1207 contains a right border sequence (RB) of A. tumefaciens used for T-DNA transcription, a terminator of Linum usitatissimum conlinin2 (TER_Linus-Cnl2), M. psirha Δ6 desaturase, and a truncated promoter of L. usitatissimum conlinin2 (PRO_Linus-Cnl2) (without 5’ 228 bp).The transgene insert in chromosome A08 of NUBJ1207 contains RB, TER_Linus-Cnl2, M. psirilla Δ6 desaturase, PRO_Linus-Cnl2, Pro_Arath-FAE1, P. cordata Δ5 elongase, Ter_Glyma-lectin, the promoter of B. napus napin (PRO_Brana-Fp1), P. satina Δ5 desaturase, TER_Agrtu-NOS, the terminator of L. usitatissimum conlinin1 (TER_Linus-Cnl1), P. pastoris Δ15 / ω3-desaturase, the promoter of L. usitatissimum conlinin1 (PRO_Linus-Cnl1), PRO_Linus-Cnl2, and 21 base pairs of P. satina Δ4-desaturase. (Note that the expression cassette described above reflects a vector design in which the genes are not arranged in the same 5’-3’ orientation). Further, with respect to the transgene insert in A08, the truncated Δ4-desaturase sequence encodes only the first 7 N-terminal amino acid residues of the enzyme and is not expected to have Δ4-desaturase activity, which is consistent with the fatty acid content observed in NUBJ1207 seed oil.

[0027] Three transgene inserts in line NUBJ1207 provide most of the genes from binary vector modB, excluding the Δ12-desaturase gene and the Δ4-desaturase gene. However, B. juncea contains endogenous Δ12-desaturase and Δ15 / ω3-desaturase genes, such that Δ12-unsaturation activity is supplemented by the endogenous genes. Additionally, line NUBJ1207 contains two copies of the Δ6-desaturase transgene. These transgene inserts convert oleic acid (OA) to DPA but do not further convert DPA to DHA due to the lack of Δ4-desaturase activity.

[0028] Accordingly, one embodiment provides seeds of the Brassica juncea line designated NUBJ1207, a representative sample of which has been deposited under ATCC Accession No. PTA-125954, wherein said seeds contain within their genome a first transgene locus located on chromosome 1 and containing P. cordata Δ6-elongase and phosphinothricin acetyltransferase, a second transgene locus located on chromosome 2 and containing M. psila Δ6-desaturase, and a third transgene locus located on chromosome 3 and containing a non-functional portion of M. psila Δ6-desaturase, P. cordata Δ5-elongase, P. salina Δ5-desaturase, Pichia pastoris Δ15 / ω3-desaturase, and P. salina Δ4-desaturase.

[0029] Since the initial transformation, the progeny have been self-pollinated and the plant breeding pedigree system has subsequently been used to develop line NUBJ1207 of this embodiment. Some of the criteria used for selection in various generations include DPA content (% of total fatty acids in the seed), vigor, fertility, standability, disease resistance, oil content, and maturity. NUBJ1207 is thus a genetically stable and homogeneous transgenic Brassica, and no off-type plants have been shown during evaluation. The NUBJ1207 line exhibits genetic stability and homogeneity as described in the phenotypic description information. It has been self-pollinated over a sufficient number of generations while paying careful attention to homogeneity with respect to plant type. This line has been increased while continuously observing for homogeneity.

[0030] A major phenotypic characteristic of NUBJ1207 is the production of a significant amount of DPA in its seeds. As shown herein, bulk seeds of NUBJ1207 generally contain about 10% DPA or more (% of total fatty acids in the seed).

[0031] At least one embodiment relates to a method for producing a DPA Brassica plant by crossing a first parent plant with a second parent plant, where the first plant or the second plant is a plant from the Brassica juncea line NUBJ1207. In at least one embodiment, both the first parent plant and the second parent plant may be from the line NUBJ1207. Any breeding method using the line NUBJ1207 is contemplated, examples of which include selfing, backcrossing, hybrid breeding, and crossing into a population. Any plant produced using the B. juncea line NUBJ1207 as a parent is within the scope of this embodiment. For example, the B. juncea line NUBJ1207 may be crossed with a canola-quality low-glucosinolate B. juncea line to provide a low-glucosinolate DPA B. juncea.

[0032] The additional methods of the present embodiment include the introduction of an expression vector to be introduced into plant tissue using a gene direct introduction method. Examples of such methods include those using microprojectile-mediated delivery, DNA injection, electroporation, or Agrobacterium-mediated transformation. In some embodiments, the transgenic variant of NUBJ1207 may contain at least one additional transgene, such as 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 additional transgenes (in addition to those present in NUBJ1207). Accordingly, the present invention also relates to super-transformed variants of the claimed line NUBJ1207, or variants obtained by breeding NUBJ1207 with one or more other transgenic Brassicas. Such transgenes are expressed under the control of regulatory sequences well known in the art (e.g., promoters, enhancers, intervening sequences, terminators). In one embodiment, the desired traits may be one or more of herbicide tolerance, pest tolerance, disease resistance, modified seed yield, modified oil percentage, modified protein percentage, modified lodging resistance, or modified fatty acid or carbohydrate metabolism. The specific gene may be any gene well known in the art or listed herein. Examples include marker genes, polynucleotides (nucleic acid molecules) conferring resistance or tolerance to imidazolinones, sulfonylureas, glyphosate, glufosinate, 2,4-D, dicamba, L-phosphinothricin, triazine, hydroxyphenylpyruvate, dioxygenase inhibitors, protoporphyrinogen oxidase inhibitors, phenoxy propionic acids, cyclohexanones, or benzonitriles, polynucleotides encoding Bacillus thuringiensis, polynucleotides encoding phytase, polynucleotides encoding 1-acyl-glycerol-3-phosphate acyltransferase (LPAAT), galactinol synthase, or raffinose synthase, or polynucleotides conferring resistance to blackleg, white rust, or other common canola diseases, but are not limited thereto.Such transgenes and related techniques are well known in the art. See, for example, U.S. Patent Nos. 9,718,759 and 8,143,488. Alternatively, the DPA traits of such transgenic embodiments may be obtained by breeding canola containing at least one transgene with NUBJ1207 as exactly described. For example, the DPA yield may be increased by introgressing NUBJ1207 with a transgenic B. napus A02 chromosome as described in U.S. Patent No. 10,563,218. The traits for producing DHA as well as DPA may be obtained, for example, by introgressing at least one complete modB insert (one locus containing two modB constructs), such as a transgenic A05 chromosome, into NUBJ1207 as described in U.S. Patent No. 10,570,405.

[0033] Accordingly, a transgene or other phenotypic trait can be introduced into NUBJ1207, or the DPA production trait of NUBJ1207 can be introduced into other Brassica or canola lines, which are performed using conventional breeding techniques such as gene transfer or backcrossing well known in the art. Examples of canola plant breeding techniques that can be utilized in producing the progeny of NUBJ1207 include, for example, recurrent selection, bulk selection, mass selection, mutation breeding, backcrossing, pedigree breeding, tissue culture, open pollination breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, doubled haploid production. Combinations of such techniques are often used. The development of Brassica subspecies in a plant breeding program typically requires the development and evaluation of homozygous subspecies. See, for example, US2018 / 0016591, U.S. Patent No. 8,143,488, Downey et al., Rapeseed & Mustard, at 437 in PRINCIPLES OF CULTIVAR DEVEL. (Fehr (ed.), Macmillan & Co., NY, 1987), Thompson, Breeding winter oilseed rape Brassica napus, 7 Adv. Appl. Biol. 1-104 (1983), Ward et al., Oilseed Rape (Farming Press Ltd., Wharefedale Road, Ipswich, Suffolk, 1985).

[0034] In another aspect of this embodiment, NUBJ1207 and its progeny can be identified not only by their phenotypic traits (i.e., the production of DPA), but also by the identification of their genotypes. As described in Example 3 of this specification, NUBJ1207 not only has a unique gene profile brought about by its transgene, but also contains unique DNA sequences at the junctions created upon insertion of the gene cassette into the B. juncea genome. More specifically, a part of the gene construct GA7-modB is present at three loci, each of which is on a different chromosome (chromosomes A08, A06, and B07), and each creates six unique junctions with unique DNA sequences.

[0035] The marker profile of NUBJ1207 can be recognized using techniques such as RFLP, random amplified polymorphic DNA (RAPD), arbitrarily primed polymerase chain reaction (AP-PCR), DNA amplified fingerprinting (DAF), sequence characterized amplified region (SCAR), amplified fragment length polymorphism (AFLP), SSR, also called microsatellite, or SNP. See, for example, Glick et al., METHODS IN PLANT MOLEC. BIOL. & BIOTECHNOL. (CRC Press, Boca Raton, 1993). An exemplary assay for the identification of NUBJ1207 junctions is the Kompetitive Allele Specific PCR (KASP) assay, the method of which is illustrated in US2018 / 0016591.

[0036] Currently, canola is recognized as an increasingly important oilseed crop and as a source of meal in many parts of the world. The DPA juncea line NUBJ1207 or its progeny can be used in the production of oil, meal, or other food or edible supplies, including nutritional supplements or pharmaceuticals, according to known techniques. Advantageously, the oil obtained from DPA juncea NUBJ1207 has a low erucic acid content (less than 1%). Glucosinolates may be found in the meal portion of the processed seeds and can be minimized by methods known in the art.

[0037] In accordance with the Budapest Treaty, the applicant has deposited the seeds of DPA B. juncea NUBJ1207 with the American Type Culture Collection (ATCCR), located at 0801 University Blvd., Manassas, Va., 20110-2209 U.S.A., under accession number PTA-125954. The applicant has met the requirements of 37 C.F.R. §§ 1.801-1.809. The applicant does not have the authority to waive any restrictions imposed by laws regarding the movement or transportation of biological materials in commerce. The applicant does not waive any rights granted under patent law or plant breeder's rights.

[0038] Accordingly, one aspect of the present embodiment provides seeds of the Brassica juncea line designated NUBJ1207 (DPA juncea NUBJ1207), and representative samples of such seeds are deposited under ATCC accession number PTA-125954. At least one embodiment provides a Brassica plant or a part thereof, which contains the genome of the seeds of DPA juncea NUBJ1207 generated by growing the seeds of DPA juncea NUBJ1207, and examples thereof include seeds, pollen, cotyledons, half-cotyledons, tissue cultures of regenerable cells, or ovules. The tissue culture or regenerable cells according to one embodiment can regenerate a plant that can express all the morphological and physiological characteristics of DPA juncea NUBJ1207, and may constitute leaves, pollen, embryos, roots, root tips, sheaths, flowers, ovules, and petioles.

Example

[0054] Example 1. Cultivation attempt (North America) Seeds obtained from the B line derived from the elite event of NUBJ1207 had the following fatty acid profile as determined by gas chromatography (Table 2).

[0055]

Table 2

[0056] The seeds were sown in the spring in Zone 7 of North America. During cultivation, specific agronomic characteristics were monitored approximately weekly as shown in Table 3 below.

[0057]

Table 3

[0058] Example 2. Cultivation attempt (Australia) Four lines of B. juncea for DPA production containing NUBJ1207 were field-trialed in separate tents in Australia, and the fatty acid content of the mature seeds (pooled bulk) was analyzed by gas chromatography (alternatively, seed fatty acids can also be measured using high-resolution NMR). Fatty acid contents where the existing fatty acids exceed 1% (of the total fatty acids %) are shown in Table 4 below. The data show consistency between the generations from bulk plants and the generations from single plants.

[0059]

Table 4

[0060] DPA B. juncea NUBJ1207 was grown in the field in southeastern Australia during the winter of 2017. Seeds were sown in May, and the resulting plants began to flower 139 days after sowing, and the seeds were harvested 218 days after sowing.

[0061] Pooled seed data from single plants from siblings of tent-grown NUBJ1207 are shown in Table 5 below. The data show consistency among siblings of the T5 generation.

[0062]

Table 6

[0065] Example 4. Unique Adjacent Regions The methods and kits of this specification are useful for identifying the presence of transgenic plant material, particularly plant material containing a transgene in NUBJ1207, as well as transgenic Brassica plants, plant material, and seeds containing such events in biological samples. The elite event NUBJ1207 described herein can be identified by genotype, which can be characterized through a genetic marker profile that can identify plants of the same cultivar or related cultivars, or can be used to determine or confirm a pedigree. The genetic marker profile can be obtained by techniques such as restriction fragment length polymorphism (RFLP), random amplified polymorphic DNA (RAPD), arbitrarily primed polymerase chain reaction (AP-PCR), DNA amplification fingerprinting (DAF), sequence characterized amplified region (SCAR), amplified fragment length polymorphism (AFLP), simple sequence repeats (SSR) (also called microsatellites), and single nucleotide polymorphisms (SNP).

[0066] For example, the elite event NUBJ1207 described herein can be identified by generating a genetic map from a sample of plant material. The genetic map can be generated by conventional RFLP, polymerase chain reaction (PCR) analysis, or SSRs that identify the approximate chromosomal location of an integrated DNA molecule encoding a heterologous protein. See Glick & Thompson, METHODS IN PLANT MOLEC. BIOL. & BIOTECHNOL. 269 (CRC Press, Boca Raton, FL, 1993). Map information regarding chromosomal location is useful for the owner protection of the transgenic plant in question. For example, the map of the integration region can be compared with a similar map of a suspect plant to determine whether the latter has a common lineage with the target plant. Examples of map comparisons can include hybridization, RFLP, PCR, SSR, and sequencing, all of which are prior art.

[0067] DPA Junscea NUBJ1207 is an inbred line from an elite event that can be characterized and identified by unique DNA sequences at the junction of the parental plant genome and the inserted transgene construct. More specifically, each of chromosomes A08, A06, and B07 contains 5' and 3' junctions unique to DPA Junscea.

[0068] For example, the DNA sequence of the 5' junction of chromosome A08 contains 100 nucleotides of B. Junscea (italicized) and 100 nucleotides of the transgene (non-italicized).

[0069]

Chemical formula

[0070] For example, the DNA sequence of the 3' junction of chromosome A08 contains 100 nucleotides of the transgene (non-italicized) and 100 nucleotides of B. Junscea (italicized).

[0071]

Chemical formula

[0072] For example, the DNA sequence of the 5' junction of chromosome A06 contains 100 nucleotides of B. Junscea (italicized) and 100 nucleotides of the transgene (non-italicized).

[0073]

Chemical formula

[0074] For example, the DNA sequence of the 3' junction of chromosome A06 contains 100 nucleotides of the transgene (non-italicized) and 100 nucleotides of B. Junscea (italicized).

[0075]

Chemical formula

[0076] For example, the DNA sequence of the 5'-junction of chromosome B07 contains 100 nucleotides of B. juncea (italic) and 100 nucleotides of the transgene (non-italic).

[0077]

Chem.

[0078] For example, the DNA sequence of the 3'-junction of chromosome B07 contains 100 nucleotides of the transgene (non-italic) and 100 nucleotides of B. juncea (italic).

[0079]

Chem.

[0080] For the identification of DPA juncea NUBJ1207, the primers for identifying the junction can be of any suitable length derived from the larger junction sequence. The length of the junction sequence used to identify DPA Juncea NUBJ1207 may be any suitable length that provides identification of the unique junction, for example, at least 10, or at least 15, or 20 consecutive nucleotides from the junction of the transgene and B. juncea DNA.
