Chlorimuron-ethyl resistance-associated protein as well as encoding gene and application thereof

The invention discloses a chlorimuron-ethyl resistance-associated protein as well as an encoding gene and application thereof. The protein provided by the invention is (a) or (b) as follows: (a) a protein composed of amino acid sequences shown in sequence 2 in a sequence table; (b) a chlorimuron-ethyl resistance-associated protein derived from the sequence 2 via substitution and/or deletion and/or addition of the amino acid sequences shown in the sequence 2 in the sequence table by one or more amino acid residues. Experiments prove that the invention provides a new protein, the chlorimuron-ethyl-resisting capacity of a genetically modified strain can be improved by transferring the encoding gene of the protein into escherichia coli to express, and then, a chlorimuron-ethyl-resisting product can be obtained. Therefore, the gene of the protein disclosed by the invention can be used for culturing high-chlorimuron-ethyl-resistance genetically modified crop varieties, and the protein has an extremely high application value.
