盐生植物活性氧的酶促清除机制

Enzymatic Mechanism of Scavenging Reactive Oxygen Species of Euh alophytes

盐生植物的耐盐性常与其有效的抗氧化系统有关。植物的抗氧化系统分为酶促反应系统和非酶促反应系统 ,其中酶促反应系统主要包括超氧化物岐化酶(SOD) ,过氧化氢酶 (CAT) ,抗坏血酸过氧化物酶 (APX) ,过氧还蛋白 (PRX)和谷胱甘肽转移酶(GST)

Plant salt tolerance is usually correlated with more e fficient antioxi dant system. Plant has evolved protection mechanism that contains enzymatic reac tion system and no-enzymatic reaction system. The enzymatic reaction system main ly includes superoxide(SOD), catalase(CAT), ascorbate peroxidase(APX), peroxidox in (PRX), glutathione S-transferase(GST) and so on.
