Abstract

Rice storage proteins (RSPs) are plant proteins with high nutritional quality. As the second largest type of storage substance in rice, it is the main source of protein intake for people who consume rice as a staple food. The content and type of RSPs affect the appearance, processing quality and eating quality of rice. These effects involve the distribution of RSPs in rice grains as well as the interactions of RSPs with other components such as starch in rice grains. In the past two decades, some progress has been made in the genetic improvement of RSPs. However, the determination mechanism of protein content and composition in rice is still unclear, and the mechanism of the effect of RSPs on rice quality has not been elucidated. In this review, the composition, biosynthesis and distribution of RSPs, and quantitative trait loci mapping and cloning of RSP genes are summarized, the research progress of the influence of RSPs and their components on rice quality are reviewed, and the research directions in the future are proposed.

稻米贮藏蛋白质的组成、分布、遗传改良及其对稻米品质的影响

水稻贮藏蛋白(RSPs)是一种营养价值较高的植物蛋白。作为大米中的第二大储存物质，它是以大米为主食的人们摄入蛋白质的主要来源。RSPs的含量和种类影响大米的外观、加工品质和食用品质。这些效应涉及水稻籽粒中RSPs的分布以及RSPs与水稻籽粒中淀粉等其他成分的相互作用。在过去的二十年中，在rsp的遗传改良方面取得了一些进展。然而，水稻中蛋白质含量和组成的决定机制尚不清楚，RSPs对稻米品质影响的机制尚未阐明。本文综述了RSP的组成、生物合成和分布、RSP基因的数量性状定位和克隆，综述了RSP及其组分对水稻品质影响的研究进展，并提出了今后的研究方向。
