The invention belongs to the technical field of
molecular biology, and particularly relates to a transgenic soybean event LP689-2 and a detection method thereof. The invention provides a
nucleic acid sequence for detecting a transgenic soybean event LP689-2, the
nucleic acid sequence is selected from one or more of sequences SEQ ID NO: 1-7 or complementary sequences thereof, and the
nucleic acid sequence is derived from the transgenic soybean event LP689-2. A representative sample of a seed of the transgenic soybean event LP689-2 is preserved in the China Center for Type Culture Collection on June 28, 2025, and the preservation number is CCTCC NO: P202519. The transgenic soybean event LP689-2 has the character of tolerance to quadruple herbicides containing 2, 4-D, HPPD inhibitors,
glufosinate-
ammonium and
glyphosate, meanwhile, the soybean yield is not reduced, and the related detection method can be used for rapidly, accurately and stably identifying the existence of
plant materials derived from the transgenic soybean event LP689-2.
