Sunflower plants resistant to herbicides, polynucleotides that encode Proteins of the largest subunit of acetohidroxiacido synthetase resistant to herbicides and Methods of use

摘要

Isolated polynucleotides encoding polypeptides of the largest Unit of acetohidroxiu00e1cido synthetase (ahasl) and herbicide resistant and wild-type and amino acid sequence of these polypeptides. In addition, expression cassettes and transforming vectors comprising these polynucleotides, as well as plants and host cells transformed with the polynucleotides.Methods of using the polynucleotides to improve the Resistance of Plants to herbicides and Methods for controlling weeds in the vicinity of Plants resistant to herbicide.Claim 1: a Sunflower Plant selected from the group which consists of: (a) a Sunflower Plant comprising in their Genome at least a copy of at least one of the largest subunit of acetohidroxiu00e1cido polynucleotide synthetase (ahasl); wherein Said polynucleotide ahasl Codi Ahasl fica a Protein resistant to herbicide comprising a threonine at position 107 or positionOn equivalent, and where the plant has a Greater resistance to at least one herbicide compared with wild-type Sunflower Plant; (b) a Sunflower Plant which includes the characteristics of Resistance to herbicides s4897, GM40, gm1606, plant with Patent at CC no PTE - 6716, or Plant Patent no ATCC PTA bags-7606; (c) The Sunflower Plant s4897,GM40, gm1606, Sunflower plant with Patent no. bags-6717 ATCC PTA or Sunflower plant with Patent no. bags-7606 ATCC PTA; The Sunflower Plant which includes the characteristics of Resistance to herbicides s4897, GM40, gm1606, Sunflower plant with Patent No ATCC PTA - 6716,Or the sunflower plant with no Patent ATCC PTA bags-7606; (e) a Sunflower Plant which is a derivative recombu00ednate Mutant, or derived by Genetic Engineering of s4897, GM40, gm1606, Sunflower plant with no Patent ATCC PTA - 6716, the sunflower Plant Tank P No detrimental ATCC PTA bags-7606 or any Progeny s4897 GM40, GM, 1606The Sunflower plant with no Patent ATCC PTA - 6716, or Sunflower plant with Patent no. bags-7606 ATCC PTA, the sunflower Plant includes the characteristics of Resistance to herbicides s4897, GM40, gm1606, Sunflower plant with no Patent ATCC PTA - 6716,Or the sunflower Plant Patent with no pre - or ATCC PTA; (f) a Sunflower plant is a Progeny of at least one of Sunflower plants (a) - (e), the sunflower Plant includes the characteristics of Resistance to herbicides s4897, GM40, gm1606, Sunflower plant with Patent no ATCC PTA - 6716,Or the sunflower plant with Patent no. bags-7606 ATCC PTA.
