Abstract

This invention relates to soybean event pDAB8264.42.32.1 and includes novel expression cassettes and transgenic inserts comprising multiple traits conferring resistance to glyphosate, aryloxyalkanoate, and glufosinate herbicides. This invention also relates in part to methods of controlling resistant weeds, plant breeding and herbicide tolerant plants. In some embodiments, the event sequence can be “stacked” with other traits, including, for example, other herbicide tolerance gene(s) and/or insect-inhibitory proteins. This invention further relates in part to endpoint TAQMAN PCR assays for the detection of Event pDAB8264.42.32.1 in soybeans and related plant material. Some embodiments can perform high throughput zygosity analysis of plant material and other embodiments can be used to uniquely identify the zygosity of and breed soybean lines comprising the event of the subject invention. Kits and conditions useful in conducting these assays are also provided.

First claim

The invention claimed is:

1. A transgenic soybean plant comprising a polynucleotide segment having SEQ ID NO:18 in its genome.

2. A soybean seed comprising a genome comprising Event pDAB8264.42.32.1 as present in representative seed deposited with American Type Culture Collection (ATCC) under Accession No. PTA-11993.

3. A soybean seed of the plant of claim 1 , said seed comprising said polynucleotide segment.

4. A soybean plant produced by growing the seed of claim 3 , said plant comprising said polynucleotide segment.

5. A progeny plant of the soybean plant of claim 4 , said progeny plant comprising Event pDAB8264.42.32.1.

6. A method of making an expression cassette for a soybean plant, said method comprising producing a heterologous polynucleotide, operably linked to a promoter, and inserting said heterologous polynucleotide operably linked to said promoter into a segment of soybean genomic DNA to produce SEQ ID NO:18.

7. A part of the plant of claim 4 , wherein said part is selected from the group consisting of pollen, an ovule, a flower, a shoot, a root, and a leaf, said part comprising said polynucleotide segment.

8. An isolated polynucleotide molecule, wherein said molecule has a sequence having SEQ ID NO:18.

9. An isolated polynucleotide, wherein said polynucleotide comprises a nucleotide sequence selected from the group consisting of SEQ ID NOs:18, 19, 20, and 21.

10. A method of breeding a soybean plant, said method comprising crossing a first soybean plant comprising a transgenic insert in genomic DNA of said first soybean plant, said transgenic insert having a sequence having SEQ ID NO:18, with a second soybean plant to produce a third soybean plant, and assaying said third soybean plant for the presence of said transgenic insert.

11. The method of claim 10 , wherein said method is used for introgressing a herbicide tolerance trait into said third soybean plant, wherein said first soybean plant comprises SEQ ID NO:19 and SEQ ID NO:20, and wherein said third soybean plant is assayed for the presence of at least one of SEQ ID NO:19 and SEQ ID NO:20.

12. A method of controlling weeds, said method comprising applying at least one of an aryloxyalkanoate herbicide, a glyphosate herbicide, a bialaphos herbicide, a phosphinothricin herbicide, and a glufosinate herbicide to a field, said field comprising the plant of claim 1 .

13. The method of claim 12 , wherein said herbicide is applied simultaneously or sequentially.

14. The method of claim 12 , wherein said aryloxyalkanoate herbicide is selected from the group consisting of 2,4-D, 2,4-DB, MCPA, and MCPB.

15. The method of claim 14 , wherein said method comprises applying at least one additional herbicide to said field.

16. The method of claim 15 , wherein said at least one additional herbicide is dicamba.

17. The method of claim 12 , wherein said method comprises planting the seed of claim 3 in the field within 14 days of applying the herbicide.

18. The method of claim 12 , wherein at least two of said herbicides are applied within the same growing season.

19. The method of claim 12 , wherein said at least one herbicide is applied over the top of said plant.

20. A stably transformed dicot plant comprising a polynucleotide having a nucleic acid molecule comprising a sequence selected from the group consisting of SEQ ID NO:18, SEQ ID NO:19, and SEQ ID NO:20.

21. The stably transformed dicot plant of claim 20 , wherein the dicot plant is from Glycine max.

22. The soybean plant of claim 1 , wherein the soybean plant is resistant to at least one herbicide selected from the group consisting of an aryloxyalkanoate herbicide, a glyphosate herbicide, and a glufosinate herbicide, and wherein said soybean plant comprises residues 1247-11507 of said SEQ ID NO:18.

23. A plant cell comprising a polynucleotide segment having SEQ ID NO:18 in its genome.

24. An isolated polynucleotide having a sequence selected from the group consisting of SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, and the complements thereof.

25. A plant cell comprising Event pDAB8264.42.32.1, wherein said plant cell comprises a first junction sequence having SEQ ID NO:19 and a second junction sequence having SEQ ID NO:20, said expression cassette comprising:
a. a first plant transcription unit which expresses a 2mepsps gene;
b. a second plant transcription unit which expresses an aad-12 gene; and
c. a third plant transcription unit which expresses a patv6 gene.
