摘　　要：植物的单价阳离子:质子逆向转运蛋白-1(CAP1)基因家族是一类在盐胁迫中起重要作用的基因,分为液泡膜单价阳离子:质子逆向转运蛋白和质膜单价阳离子:质子逆向转运蛋白两大类,在植物的发育和生长过程中起到很重要的作用。不同的成员在植物中的表达特性不同。主要综述了此类基因的结构、启动子活性、表达情况及其主要功能。The monovalent cation：proton antiporter-1 family plays important roles in salt stress in plants. AtNHX1-6 and AtNHX7-8 have been characterized as tonoplast and plasma membrane monovalent cation：proton antiporter,respectively. This family is reported to be involved in development and growth of plant,in which every member shows different expression patterns. In this paper, the structure,promoter activity, expression patterns and functions of monovalent cation：proton antiporter-1 family were summarized.
