谷胱甘肽（GSH; γ-谷氨酰半胱氨酰甘氨酸）是一种丰富且普遍存在的硫醇，其在还原硫的储存和运输、蛋白质和核酸的合成中以及作为酶活性的调节剂中具有建议的作用。谷胱甘肽的水平也被证明与植物对极端温度的适应、植物对异生物质的耐受性以及对生物和非生物环境胁迫的耐受性相关。此外，还原型谷胱甘肽池的大小显示出显着的变化，在一些环境条件的响应。总之，这些发现促使人们努力详细描述植物谷胱甘肽稳态的机制，并阐明这些反应在植物适应环境胁迫的策略中的作用。本文综述了近年来植物谷胱甘肽稳态的生物化学、分子、遗传、和生理学的进展，这是增加我们的理解机制，其中植物谷胱甘肽稳态的控制和谷胱甘肽的作用，在整合的细胞，植物在逆境下的生长发育过程。
Glutathione (GSH; gamma-glutamylcysteinyl glycine) is an abundant and ubiquitous thiol with proposed roles in the storage and transport of reduced sulphur, the synthesis of proteins and nucleic acids and as a modulator of enzyme activity. The level of glutathione has also been shown to correlate with the adaptation of plants to extremes of temperature, in the tolerance of plants to xenobiotics and to biotic and abiotic environmental stresses. In addition, the size of the reduced glutathione pool shows marked alterations in response to a number of environmental conditions. Taken together, these findings have prompted intense efforts to characterize in detail the mechanisms underlying glutathione homeostasis in plants and to elucidate the role of these responses in the strategies plants have evolved to adapt to environmental stresses,The aim of this review is to assess recent biochemical, molecular, genetic, and physiological advances which are increasing our understanding of the mechanisms by which plant glutathione homeostasis is controlled and the role of glutathione in the integration of cellular processes with plant growth and development under stress.
