Abstract
The present invention relates to mutant AHAS enzymes that are specifically resistant to imidazolinone herbicides. Exemplary of these is a corn sequence, which encodes an amino acid substitution at position 621 of the wild-type AHAS enzyme. Polynucleotides encoding the mutant enzyme can be used in screening methods for identifying plant cells that have been transformed.
Claims3
An isolated functional corn AHAS enzyme which has an amino acid substitution at position 621 relative to the wild-type corn AHAS enzyme, which substitution confers imidazoline-specific resistance to the enzyme.
