Herbicide-resistant sunflower plants, isolated polynucleotides that encode herbicide-resistant and wild-type acetohydroxyacid synthase large subunit (AHASL) polypeptides, and the amino acid sequences of these polypeptides, are described. Expression cassettes and transformation vectors comprising the polynucleotides of the invention, as well as plants and host cells transformed with the polynucleotides, are described. Methods of using the polynucleotides to enhance the resistance of plants to herbicides, and methods for controlling weeds in the vicinity of herbicide-resistant plants are also described.
La présente invention concerne des tournesols résistant aux herbicides, des polynucléotides isolés codant pour des polypeptides d~une grande sous-unité de l~acétohydroxyacide synthase (AHASL) de type sauvage et résistant aux herbicides, et les séquences d~acides aminés de ces polypeptides. L~invention concerne également des cassettes d~expression et des vecteurs de transformation comprenant les polynucléotides de l~invention ainsi que des végétaux et des cellules hôtes transformées à l~aide des polynucléotides. La présente invention concerne en outre des procédés d~utilisation des polynucléotides en vue de favoriser la résistance de végétaux à des herbicides, et des procédés permettant de contrôler le désherbage à proximité des végétaux résistant aux herbicides.
