Abstract
A mutant acetyl-CoA carboxylase (ACC) protein, a nucleic acid encoding the mutant ACC protein, and use thereof are provided. Specifically, compared with a parent ACC protein, the mutant ACC protein has mutations at amino acids corresponding to amino acid 1,879 and/or amino acid 2,186 of SEQ ID NO: 1. An ACC-mutated plant shows high herbicide resistance, and thus the present disclosure has very promising application prospects in the cultivation of an herbicide-resistant plant.
Claims8
A method for imparting phenthodim resistance to a plant, comprising a step of allowing endogenous acetyl-CoA carboxylase (ACC) of the plant to mutate to introduce a mutant ACC into a plant cell, a plant seed, a plant tissue, a plant part, or the plant, wherein compared to an amino acid sequence of a parent ACC, the mutant ACC has a mutation at an amino acid corresponding to amino acid 1,879 of an amino acid sequence shown in SEQ ID NO:
- 1, wherein the amino acid 1,879 is mutated into valine (V);
- and
- the plant is rice;
- wherein a method for controlling weeds comprises:
- a) providing a phenthodim-resistant plant prepared by the method for imparting the phenthodim resistance to the plant;
- and
- b) applying an effective amount of phenthodim to the phenthodim-resistant plant and the weeds nearby to control the weeds near the phenthodim-resistant plant.
