摘要:

谷胱甘肽(GSH)是广泛存在于植物体内的一种重要的抗氧化物质,可以清除细胞代谢中产生的多余活性氧自由基,从而减少膜脂过氧化对细胞造成的伤害。谷胱甘肽二硫化物(GSSG)是GSH的氧化形式。近年来研究发现谷胱甘肽氧化还原对(GSH/GSSG)作为信号分子在植物应对逆境胁迫中起重要作用。本文综述了近年来GSH,尤其是 GSH/GSSG的作用,为后续通过调控GSH/GSSG调节植物抗性提供参考。

Abstract:

Glutathione(GSH)is an important antioxidant substance that widely exists in plants. It can eliminate the excess reactive oxygen radicals produced in cell metabolism,thus reducing the damage of membrane lipid peroxidation to cells. Glutathione disulfide(GSSG)is the oxidation form of GSH. In recent years,it has been found that the glutathione/glutathione disul?de redox couple(GSH/GSSG)also plays an important role as a signal molecule in plant stress response. This paper reviews the role of GSH/GSSG in plant response to stress,which provides theoretical basis for the regulation of plant resistance by regulating GSH/GSSG.

Key words: glutathione, abiotic stress, signal transduction, defense mechanism
