Abstract
The present invention is directed to nucleic acids encoding polypeptides that confer upon a plant tolerance to an imidazolinone and/or other acetohydroxyacid synthase (AHAS) inhibiting herbicide when expressed in the plant. The present invention also provides plants having increased tolerance to an imidazolinone and/or other AHAS-inhibiting herbicide. More particularly, the present invention includes plants containing at least one IMI nucleic acid. The present invention also includes seeds produced by these plants and methods of controlling weeds in the vicinity of these wheat plants.
Claims17
A wheat or triticale plant, wherein the plant is obtained by a process comprising crossing a plant of line Shiloh-8, a representative sample of seed of the line having been deposited with American Type Culture Collection (ATCC) under Patent Deposit Designation Number PTA-5625, with another wheat or triticale variety, wherein the plant comprises a Shiloh-8 Imi1 nucleic acid, said Shiloh-8 Imi1 nucleic acid comprising a polynucleotide sequence encoding an IMI polypeptide having an alanine to threonine substitution in Domain C, said polynucleotide sequence is that of the D genome, and said plant having increased tolerance to the imidazolinone herbicide as compared to that of a wild-type wheat or triticale plant.
