The present disclosure relates to, inter alia, a weed control method. In one example, a method comprises applying to the locus a weed controlling amount of a pesticide composition comprising a FatA acyl-ACP thioesterase-inhibiting herbicide, wherein the crop plants are modified such that they comprise a FatA acyl-ACP thioesterase which provides the crop plant with tolerance against the FatA acyl-ACP thioesterase-inhibiting herbicide. Recombinant polynucleotides and suitable for use in the methods, and edited FatA acyl-ACP thioesterases are also disclosed.

Weed control methods and related compositions and plants

Novel hydroxyphenyl pyruvate dioxygenase (HPPD) polypeptides, variants and fragments thereof, as well as polynucleotides encoding the same, capable of conferring commercial levels of conferring HPPD herbicide resistance or tolerance to plants. Compositions include amino acid sequences, and variants and fragments thereof, for HPPD polypeptides, as well as polynucleotides encoding the same. Methods for the production and use of HPPD herbicide resistant plants that express these novel HPPD polypeptides, methods for selectively controlling weeds in a field at a crop locus, and methods for the assay, characterization, identification and selection of these novel HPPDs are also provided.

Hydroxyphenylpyruvate dioxygenase polypeptides and methods of use

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.
