摘要 谷胱甘肽过氧化物酶(Glutathione Peroxidase,GPX)是植物体内清除活性氧自由基的重要酶类之一,在保护膜免受氧化损伤中发挥重要作用.目前在一些植物中已经克隆获得了编码GPXs的基因序列.通过对拟南芥、杨树和百脉根等植物GPXs基因结构和功能的分析,研究植物GPXs基因结构及其在胁迫应答中的表达变化,总结了植物GPXs在抗逆应答反应中的可能作用. Glutathione Peroxidase(GPX) is one of the main enzymes scavenging reactive oxygen species(ROS) in plants,playing an important role in protecting membranes from the oxidative damage.So far,some sequences of GPX genes have been cloned in plants.Structures,functions of GPX genes were analyzed in Arabidopsis thaliana,Populus trichocarpa and Lotus japonicus.Plant GPX genes structures and expression changes under stress treatments were studied,and the effect of GPXs in plants on stress tolerance was summarized.
