中文摘要：

非生物胁迫因子如高盐、干旱、低温、重金属污染等严重影响植物的生长和繁殖。植物进化出一系列包括各种酶类物质的系统抵抗逆境所带来的氧化伤害。谷胱甘肽转移酶（glutathione S-transferase,GST,EC 2.5.1.18）是由多种功能的蛋白质组成的超家族,在植物遭受高盐、干旱、低温胁迫时,GSTs可清除活性氧,保护植物细胞膜结构和蛋白质活性。对谷胱甘肽转移酶在植物抵御非生物胁迫中的作用进行综述,为今后利用基因工程育种提供理论依据。

英文摘要：

stresses,such as high salt,drought,low temperature and heavy metal pollution,have seriously affected the growth and reproduction of plants. Meanwhile,plants have evolved a series of various enzymes system against oxidative damage caused by abiotic and biotic stresses. Glutathione S-transferase,which comprise a large superfamily of multifunctional protein,can scavenge reactive oxygen species and protect plant cell membrane structure and protein activity when plants were subjected to high salt,drought and low temperature stresses. The role of GST in plant response to abiotic stress is reviewed,and this will provide valuable information for the plant genetic engineering in the future.
