Problems solved by technology

Only thifensulfuron-methyl hydrolase has been identified that can degrade thifensulfuron-methyl, but like thifensulfuron-methyl, clopyrazol-methyl also belongs to the sulfonylurea herbicides containing ester bonds, and thifensulfuron-methyl hydrolase has not been found to degrade chlorpyramid-methyl. Reports of tolerance to pyrazosulfuron-methyl herbicide

Abstract

The invention relates to an application of protein having tolerance to herbicides. A method for controlling weeds includes applying a herbicide containing an effective dose of halosulfuron-methyl to a plant growing environment with at least one type of transgenic plant. As a genome of the transgenic plant comprises nucleotide sequences of encoding thifensulfuron methyl hydrolase, the transgenic plant has low damage and / or high yield as compared with the plant without the nucleotide sequences of the encoding thifensulfuron methyl hydrolase. According to the invention, the thifensulfuron methyl hydrolase has high tolerance to the herbicide containing halosulfuron-methyl, further, the plant containing the nucleotide sequences of the encoding thifensulfuron methyl hydrolase has high tolerance to the herbicide containing halosulfuron-methyl and is capable of tolerating one time of field concentration at least, and thus the thifensulfuron methyl hydrolase has wide application prospect in the field of plants.

Description

technical field [0001] The present invention relates to the use of a herbicide tolerance protein, in particular to the use of a thifensulfuron-methyl hydrolase to degrade chlorpyrazosulfuron-methyl herbicide. Background technique [0002] Weeds can quickly deplete the soil of valuable nutrients needed by crops and other plants of interest. There are many types of herbicides currently used to control weeds, one particularly popular herbicide is glyphosate. Glyphosate-resistant crops have been developed, such as corn, soybean, cotton, sugar beet, wheat and rice. Fields of glyphosate-resistant crops can thus be sprayed with glyphosate to control weeds without significantly damaging the crop. [0003] Glyphosate has been widely used globally for more than 20 years, resulting in an overreliance on glyphosate and glyphosate-tolerant crop technologies, and in wild weed species that are naturally more tolerant to glyphosate or have developed Plants exhibiting glyphosate resistanc...
