The present invention relates to a kind of purposes of herbicide tolerant protein, the method of the control weeds includes that the herbicide containing effective dose pyrazosulfuron is applied to there are in the plant growth environment of at least one genetically modified plants, the genetically modified plants include the nucleotide sequence for encoding thifensulfuronmethyl hydrolase in its genome, and the genetically modified plants with the plant injury weakened and/or have increased plant products compared with other do not have the plant of the nucleotide sequence of coding thifensulfuronmethyl hydrolase.Present invention firstly discloses thifensulfuronmethyl hydrolases, and higher tolerance can be shown to pyrazosulfuron herbicide, and the plant containing coding thifensulfuronmethyl hydrolase nucleotide sequence is strong to the tolerance of pyrazosulfuron herbicide, it can be at least resistant to 1 times of crop field concentration, therefore had a extensive future on plant. |
