Abstract: Starch is the major storage material of rice (Oryza sativa) endosperm, and its accumulation process affects the subsequent growth and development of plants. As one of the main nutrients absorbed by human beings from rice, the synthesis and accumulation process of starch in rice has attracted increasing attention. This review mainly discusses the latest progress of endogenous factors affecting starch synthesis and accumulation, such as sucrose unloading from phloem, key enzymes of starch synthesis and hormones, and points out the unsettled questions in the field of endosperm starch accumulation to provide some reference ideas for further research in the future.

Key words: starch, endosperm, sucrose unloading, starch synthase, hormone
