摘要： The storability of rice seeds is crucial for ensuring flexible planting options, agricultural seed security, and global food safety. With the intensification of global climate change and the constant fluctuations in agricultural production conditions, enhancing the storability of rice seeds has become particularly important. Seed storability is a complex quantitative trait regulated by both genetic and environmental factors. This article reviews the main regulatory mechanisms of rice seed storability, including the accumulation of seed storage proteins, late embryogenesis abundant (LEA) proteins, heat shock proteins, sugar signaling, hormonal regulation by gibberellins and abscisic acid, and the role of the ubiquitination pathway. Additionally, this article explores the improvement of storability using wild rice genes, molecular marker-assisted selection, and gene editing techniques such as CRISPR/Cas9 in rice breeding. By providing a comprehensive scientific foundation and practical guidance, this review aims to promote the development of rice varieties with enhanced storability to meet evolving agricultural demands.
