| 摘 要： | 土壤盐碱化是造成农作物减产的主要原因之一。质膜Na^＋／H^＋逆向转运蛋白能够介导植物根部Na^＋的外排和体内Na^＋的长距离运输, 并能够调控细胞K＋的稳态平衡及细胞内pH值和Ca^2＋的转运, 因此其在植物耐盐性方面具有重要作用。该文概述了植物质膜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关系等方面的研究进展, 并对今后有关该蛋白的主要研究方向作了分析和展望。

| Abstract: | Soil salinization is one of the major abiotic factors reducing crop productivity worldwide.The plasma mem-brane Na+/H+ antiporter plays an important role in plant salt tolerance because it is involved in Na+ exclusion in roots,long-distance Na+ transport in plants and the regulation of cellular K+,pH homeostasis and Ca2+ transport.In this review,we analyze recent advances in molecular structure and function,including expression and regulation of the plasma membrane Na+/H+ antiporter,and its role in plant sa... |
