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 one or more of amino acid 237, amino acid 168, and amino acid 411 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.
