摘要: 高质量种子是高水平农业的重要体现。在全国种业蓬勃发展的背景下,种子活力研究近年来逐渐成为行业研究的热点与重点。探索种子活力调控机制对未来种质创新、良种繁育、种质资源保存、种子加工贮藏及质量控制等具有重要价值。谷胱甘肽(Glutathione,GSH)是植物体内不可替代的氧化还原缓冲剂,其相关代谢和调控因子在种子活力维持中的关键作用近年来逐渐被报道。本文系统综述了GSH在种子发育、老化及萌发过程中的动态代谢规律,重点阐述了GSH通过调节活性氧平衡、介导蛋白质氧化还原修饰、维持线粒体结构与功能、促进活性羰基物质解毒以及参与细胞信号转导等多种途径调控种子活力的分子机制。在此基础上,本研究整合了外源GSH处理对种子活力的影响证据,构建了GSH参与种子活力调控的主要途径模型,并针对当前研究存在的关键问题,提出了GSH在种子活力研究领域的未来发展方向和创新性研究思路。

Abstract: High-quality seed is a key indicator of advanced agricultural practices. With the national focus on the development of the seed industry, research on seed vigor has become an increasingly prominent and prioritized topic in recent years. Understanding the mechanisms that regulate seed vigor are crucial for future advancements in germplasm innovation, breeding of improved varieties, germplasm resource conservation, seed processing, storage, and quality control. As an irreplaceable redox buffer in plants, glutathione (GSH) and its associated metabolism and regulatory factors have been increasingly recognized for their critical role in seed vigor. This review systematically examined the dynamic metabolic regulation of GSH throughout seed development, aging, and germination processes. We highlighted the multifaceted roles of GSH in maintaining seed vigor through its involvement in reactive oxygen species homeostasis, protein redox modifications, mitochondrial structure and function preservation, detoxification of reactive carbonyl compounds, and interactions with diverse signaling molecules. By synthesizing current evidence on exogenous GSH applications and their impacts on seed performance, we proposed an integrated model depicting GSH-mediated pathways in seed vigor regulation. The review concluded by identifying critical research gaps and suggesting promising avenues for future investigations to advance our understanding of GSH functions in seed biology and its potential applications in seed quality improvement.
