摘　　要：SOS(Salt Overly Sensitive)信号转导途径是目前研究最清楚的耐盐机理之一,总结了SOS基因介导信号转导过程中的6个关键基因(SOS1、SOS2、SOS3、SOS4、SOS5、SOS6)的结构,并分析其与植物的耐盐性的分子机理,通过对SOS途径关键基因的结构及其功能进行分析,深刻剖析关键基因之间的互作关系,并对可能的基因功能及互作关系提出了假设,指出SOS途径网络调控模式,并对今后SOS调控网络研究方向进行了展望。SOS （Salt Overly Sensitive） mediated signal transduction pathway was one of the most clearly studied mechanisms of salt tolerance, some of the plants under salt stress, six genes of SOS gene family were indifferent time and space to expression caused damage by salt. In this paper, SOS-mediated signal transduction process and its function were reviewed. The molecular mechanism of the six key genes was analyzed on Arabidopsis. And than, tryptophan-niacin relationship were analyzed among key genes in SOS metabolic pathway. The hypothesis was obtained about new functions and tryptophan-niacin relationship of key genes in SOS metabolic pathway. At same time, the model of network regulation was refereed in SOS metabolic pathway. At last, the research direction of network regulation was proposedd in future.
