摘要/Abstract

摘要：

土壤盐碱化作为一种主要的非生物胁迫因子严重影响着世界范围内的农业生产。植物抵御盐胁迫的有效策略之一是将细胞质中过多的Na^＋区隔化在液泡，这一过程是由液泡膜Na^＋／H^＋逆向转运蛋白完成的。本文概述了植物液泡膜Na^＋／H^＋逆向转运蛋白的分子结构、功能、表达调控及其与植物耐盐性的关系等方面的研究进展，并对未来几
年该蛋白的主要研究方向作了分析和展望。

关键词: 盐胁迫液泡膜Na^＋／H^＋逆向转运蛋白耐盐性

Abstract:

Soil salinization Js a major abiotic factor that adversely affects worldwide agricultural production. One of the effective strategies that enable plants to resist salt stress is to compartmentalize Na^＋ into the vacuole, which is accomplished by the vacuolar Na^＋/H^＋ antiporter. In this paper, recent progresses on molecular structure and function, expression and regulation of the vacuolar Na^＋/H^＋ antiporters, and their roles in plants salt tlerance were summarized; the future goals of this research field were also discussed.

Key words: salt stress, vacuolar Na^＋／H^＋ antiporter, salt tolerance
