Mutant hydroxyphenylpyruvate dioxygenase polypeptides and methods of use |
摘要 |
Compositions and methods for conferring hydroxyphenyl pyruvate dioxygenase (HPPD) herbicide resistance or tolerance to plants are provided. Compositions include amino acid sequences, and variants and fragments thereof, for mutant HPPD polypeptides. Nucleic acids that encode the mutant HPPD polypeptides are also provided. Methods for conferring herbicide resistance or tolerance, particularly resistance or tolerance to certain classes of herbicides that inhibit HPPD, in plants are further provided. Methods are also provided for selectively controlling weeds in a field at a crop locus and for the assay, characterization, identification and selection of the mutant HPPDs of the current invention that provide herbicide tolerance. |
