US 11,952,582 B2 · Herbicide-resistance gene and application thereof in plant breeding

Abstract

Provided are a mutant HPPD polypeptide having high resistance to a herbicide and an encoding gene thereof, and an application thereof in an improved plant. The amino acid at position 282 of the mutant HPPD polypeptide is mutated from arginine to serine at a wild-type HPPD polypeptide. In addition, the mutant HPPD polypeptide further comprises an amino acid at position 349 that is mutated from glutamic acid to lysine, and/or an amino acid at position 156 that is mutated from alanine to valine. The mutated HPPD polypeptide can be used for cultivating plants having resistance to a herbicide having HPPD inhibition.
