摘    要:植物在生长过程中会面临各种各样的胁迫,为了自我保护,植物进化出了多种抵御胁迫的策略。植物谷胱甘肽-S-转移酶(glutathione-S-transferases,GSTs,EC2.5.1.18)可以催化亲核性的谷胱甘肽(glutathione,GSH)与各种亲电子外源化学物的结合反应,降低细胞体内活性氧(reactive oxygen species,ROS)水平,从而减轻非生物胁迫对植物的损伤。本文主要概述了GSTs在植物抗非生物胁迫的作用。

关 键 词:谷胱甘肽-S-转移酶  非生物胁迫  转基因植物

Abstract:Plant growth and development is affected by various stress factors. For self-protection,they have evolved a number of strategies to resist stresses. Glutathione-S-transferases (GSTs,EC 2.5.1.18) can catalyze the conjugation of various electrophiles with GSH and decreased cell reactive oxygen species (ROS) level,which protect plant against the abiotic stress. This paper summarized the role of GSTs in abiotic stress resis-tance in plants.
Keywords:glutathione-S-transferases  abiotic stress  transgenic plant
