WHEAT PLANTS HAVING INCREASED RESISTANCE TO IMIDAZOLINONE HERBICIDES

摘要

The present invention is directed to wheat plants having increased resistance to an imidazolinone herbicide. More particularly, the present invention includes wheat plants containing one or more IMI nucleic acids such as a Teal IMI cultivar. The nucleic acids are preferably located on or derived from different genomes. The present invention also includes seeds produced by these wheat plants and methods of controlling weeds in the vicinity of these wheat plants.

主权项

1. A wheat plant, wherein the wheat plant was obtained by a process comprising crossing a plant of line Teal11A with a plant of another wheat line, a representative sample of seed of the line Teal11A having been deposited with American Type Culture Collection (ATCC) under Patent Deposit Designation Number PTA-3953 and the wheat plant comprises a Teal11A Imi2 nucleic acid, said Teal11A Imi2 nucleic acid comprising a polynucleotide sequence encoding an IMI polypeptide having a serine to asparagine substitution in Domain E, said Imi2 nucleic acid being that of the B genome, and said wheat plant exhibiting increased tolerance to an imidazolinone herbicide as compared to that of a wild-type wheat plant.
