| 摘 要： | 谷胱甘肽(GSH)是一种普遍存在于植物中的抗氧化剂,在维持组织抗氧化防御和调节氧化还原敏感信号转导中起着关键作用。深入研究GSH在非生物胁迫中的作用,对从分子水平揭示植物GSH积累的调控机制具有重要意义。本研究从植物GSH代谢途径及其相关酶、GSH在植物应激反应中的调节、GSH参与植物激素代谢等方面进行综述,并对谷胱甘肽在植物生长发育、与其它信号通路间交互作用的研究前景进行展望,以期为植物谷胱甘肽代谢以及其在非生物胁迫方面的研究提供一定的理论参考。

| Abstract: | Glutathione(GSH)is an abundant and ubiquitous antioxidant,which plays a key role in the maintenance of tissue antioxidant defence and in the regulation of redox-sensitive signal transduction.In-depth study of the role of GSH in abiotic stress is of great significance for revealing the regulation mechanism of plant GSH accumulation at the molecular level.This review summarized the GSH metabolic pathway and its related enzymes,the regulation of GSH in plant stress response,and the involvement of GSH in plant hormone metabolism.The research prospects of glutathione interaction between plants and other signaling pathways are prospected.And this research provided a theoretical reference for the study of plant glutathione metabolism and its research on abiotic stress. |
