Methods for controlling weeds in the vicinity of a sunflower plant, to increase the activity of tabs in a plant to produce a plant resistant to the herbicide, to improve tolerability R {erbicida in a plant tolerant to rerbicida, to select a cell of the plant trans Formed, for controlling weeds in the vicinity of a plant transformed.In order to increase the resistance to the herbicide to a plant and for combating unwanted vegetation, CAS seven of expression, the host cell is not human, vector processing and composition.Sunflower plants resistant to the herbicide, isolated polynucleotides encoding polypeptides that encode subunit of Aceto - hydroxy acid synthase (AI - IASL), resistant to the herbicide and wild type, and the amino acid sequences of these polypeptides are described.The expression cassette vectors comprising the polynucleotides encoding and processing of the invention, as well as plants and host cells transformed with the polynucleotides encoding are described. Methods of using the polynucleotides encoding to improve the resistance of plants to herbicides, and methods for controlling weeds in the vicinity of herbicide resistant plants are also described.
