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.
水稻种子的贮藏能力对于确保灵活的种植选择、农业种子安全和全球食品安全至关重要。随着全球气候变化的加剧和农业生产条件的不断波动，提高水稻种子的贮藏能力变得尤为重要。种子贮藏能力是一个受遗传和环境因素共同调控的复杂数量性状。本文综述了水稻种子贮藏能力的主要调控机制，包括种子贮藏蛋白、晚期胚胎丰富蛋白（LEA）、热激蛋白、糖信号、赤霉素和脱落酸的激素调节，以及泛素化途径的作用。此外，本文还探讨了利用野生稻基因、分子标记辅助选择和 CRISPR/Cas9 等基因编辑技术在水稻育种中提高贮藏能力的方法。通过提供全面的科学基础和实用指导，本文旨在促进具有增强贮藏能力的水稻品种的发展，以满足不断变化的农业需求。
