IMIDAZOLINONE RESISTANT AHAS MUTANTS

摘要

31440-00 IMIDAZOLINONE RESISTANT AHAS MUTANTS The present invention relates to monocot genes encoding a mutant AHAS enzyme that is specifically resistant to imidazolinone herbicides. Exemplary of these genes are corn DNA sequences which encode an amino acid substitution at position 621 of the wildtype AHAS enzyme. The mutant gene can be used to transform other plants to herbicide resistance; in this regard, the invention also provides host cells and vectors containing the gene, which cells and vectors are useful in the transformation process.
