Abstract
A mutant granule-bound starch synthase 1 (GBSS1) polypeptide and a nucleic acid, and use thereof are provided. Compared to an amino acid sequence of a parent GBSS1, the mutant GBSS1 polypeptide has a mutation at an amino acid corresponding to amino acid 427 and/or amino acid 428 of an amino acid sequence shown in SEQ ID NO: 1. An amylose content (AC) in a plant changes after the plant undergoes GBSS1 mutation, which has very promising application prospects in the improvement of edible quality of rice.
