Transgenic Soybean Event XP-2 and Detection Method Thereof

A specific nucleotide sequence for detecting the transgenic soybean event XP-2, wherein the specific nucleotide sequence has at least 11 consecutive nucleotides of one of the nucleotide sequences shown in SEQ ID NO:1-10, or their complementary sequences.

A primer pair, wherein the primer pair comprises a first primer and a second primer different from the first primer, and the first primer and the second primer each comprise a portion of SEQ ID NO:10 or its complementary sequence for detecting the transgenic soybean event XP-2 in a sample.

A DNA probe, wherein the DNA probe comprises a portion of SEQ ID NO:10 or its complementary sequence, wherein the DNA probe hybridizes under stringent hybridization conditions to DNA containing any of SEQ ID NO:1-10 or their complementary sequences, but does not hybridize to DNA lacking these sequences.

A method for cultivating herbicide-tolerant soybean plants containing the transgenic soybean event XP-2, wherein the method comprises:

• planting soybean seeds containing a specific nucleotide sequence, spraying a herbicide, and harvesting soybeans having significantly enhanced herbicide tolerance compared to other soybean plants lacking the specific nucleic acid sequence;
• wherein the specific nucleotide sequence is selected from one of SEQ ID NO:1-10, or their complementary sequences.

A method for controlling field weeds in the cultivation of soybean plants containing the transgenic soybean event XP-2, wherein the method comprises:

• planting transgenic soybean plants containing a specific nucleotide sequence, and spraying with effective doses of glyphosate and/or flazasulfuron herbicides to control the weeds;
• wherein the transgenic soybean genome comprises the specific nucleotide sequence from the transgenic soybean event XP-2, which is selected from one of SEQ ID NO:1-10, or their complementary sequences.

A method for obtaining flazasulfuron-tolerant and/or glyphosate-tolerant soybean plants based on the transgenic soybean event XP-2, wherein the method comprises:

• hybridizing the soybean plant containing a specific nucleotide sequence with another soybean plant to produce progeny plants;
• harvesting plants with significantly enhanced tolerance to herbicides compared to plants lacking the specific nucleotide sequence;
• wherein the specific nucleotide sequence is derived from the transgenic soybean event XP-2 and selected from one of SEQ ID NO:1-10, or their complementary sequences.

A soybean commodity or agricultural product produced from the transgenic soybean event XP-2, wherein the soybean commodity or agricultural product contains a detectable DNA molecule originating from the specific nucleotide sequence of the transgenic soybean event XP-2, which is selected from one of SEQ ID NO:1-10 or their complementary sequences;

• the soybean commodity or agricultural product is selected from the group consisting of:
• soybean oil, soybean protein, soybean meal, soybean flour, soybean flakes, soybean hulls, soymilk, soy cheese, soy wine, animal feed containing soybeans, paper containing soybeans, cheese containing soybeans, soybean biomass, and fuel products produced using soybean plants and soybean plant parts.
