herbicide tolerant protein and gene, expression cassette, recombinant vector, methods for producing a herbicide tolerant protein, for increasing the range of herbicides that can be tolerated, for selecting transformed plant cells, for controlling herbs, for protecting a plant, for give a plant sulfonylurea herbicide tolerance, to produce and cultivate a plant that is tolerant of a sulfonylurea herbicide, planting system, use of a herbicide tolerant protein.

摘要

a herbicide tolerant protein, sum1, a coding gene, and a use thereof. said herbicide tolerant protein includes: (a) a protein having an amino acid sequence as set forth in sequence: 1; or (b) a protein derived from (a) by substitution and / or deletion and / or addition of one or more amino acids in the amino acid sequence of (a) and which has tifensulfuron-methyl hydrolase activity. The herbicide tolerant protein may exhibit a tolerance greater than multiples of sulfonylurea herbicides, may have a tolerance of up to four times the field concentration, and therefore has a broad plant application perspective.
