ABSTRACT:
A nucleic acid fragment encoding a herbicide-resistant plant acetolactate synthase protein is disclosed. This nucleic acid fragment contains at least one nucleotide mutation resulting in one amino acid change in one of seven substantially conserved regions of acetolactate synthase amino acid homology. This mutation results in the production of an acetolactate synthase protein which is resistant to sulfonylurea herbicide compounds compared to the wild-type protein. Transformation of herbicide sensitive plants or plant cells with the fragment results in resistance to the herbicide.
