Abstract
The invention pertains to transgenic cotton plants, plant material and seeds, characterized by harboring a specific transformation event, particularly by the presence of a gene encoding a protein that confers herbicide tolerance, at a specific location in the cotton genome. The cotton plants of the invention combine the herbicide tolerant phenotype with optimal agronomic performance.
Claims15
A method for identifying elite event EE-GH1 in biological samples, said method comprising amplifying a DNA fragment of between 100 and 350 bp from a nucleic acid present in said biological samples using a polymerase chain reaction with at least a first and a second primer, said first primer comprising a nucleotide sequence of 15 to 35 contiguous nucleotides selected from the nucleotide sequence of SEQ ID NO:
- 1 from nucleotide 1 to nucleotide 677 and said second primer comprising a nucleotide sequence of 15 to 35 contiguous nucleotides selected from the nucleotide sequence of SEQ ID NO:
- 6 from nucleotide 198 to nucleotide 2544 or the complement thereof or selected from the complement of the nucleotide sequence of SEQ ID NO:1 from nucleotide 678 to nucleotide 850.
A method for identifying elite event EE-GH1 in biological samples, said method comprising amplifying a DNA fragment of between 100 and 350 bp from a nucleic acid present in said biological samples using a polymerase chain reaction with at least a first and a second primer, wherein said first primer comprises the sequence of SEQ ID NO:
- 2 and said second primer comprising a nucleotide sequence of 15 to 35 contiguous nucleotides selected from the nucleotide sequence of SEQ ID NO:
- 6 from nucleotide 198 to nucleotide 2544 or the complement thereof or selected from the complement of the nucleotide sequence of SEQ ID NO:1 from nucleotide 678 to nucleotide 850.
A method for identifying a transgenic plant, or cells or tissues thereof, comprising the elite event EE-GH1, which method comprises amplifying a DNA fragment of between 250 and 290 bp from a nucleic add present in said biological samples using a polymerase chain reaction with at least a first and a second primer having the nucleotide sequence of SEQ ID NO:
- 3 and SEQ ID NO:
- 2, respectively.
A kit for identifying elite event EE-GH1 in biological samples, said kit comprising a first PCR primer, comprising a nucleotide sequence of 15 to 35 contiguous nucleotides selected from the nucleotide sequence of SEQ ID NO:
- 1 from nucleotide 1 to nucleotide 677 and a second PCR primer comprising a nucleotide sequence of 15 to 35 contiguous nucleotides selected from the nucleotide sequence of SEQ ID NO:
- 6 from nucleotide 198 to nucleotide 2544 or the complement thereof, or selected from the complement of the nucleotide sequence of SEQ ID NO:
- 1 from nucleotide 678 to nucleotide 850.
A kit for identifying elite event EE-GH1 in biological samples, said kit comprising a first PCR primer comprising the sequence of SEQ ID NO:
- 2 and a second PCR primer comprising a nucleotide sequence of 15 to 35 contiguous nucleotides selected from the nucleotide sequence of SEQ ID NO:
- 6 from nucleotide 198 to nucleotide 2544 or the complement thereof, or selected from the complement of the nucleotide sequence of SEQ ID NO:
- 1 from nucleotide 678 to nucleotide 850.
A kit for identifying elite event EE-GH1 in biological samples, said kit comprising a probe, said probe comprising a sequence of 50 to 500 contiguous nucleotides which is identical to or complementary to the sequence of plant DNA and foreign DNA at each side contiguous with the insertion site contained in SEQ ID NO:
- 1.
