【摘要】 植物抵御盐害的主要方式是增加Na+的外排、减少Na+的吸入和Na+的区隔化,而Na+的跨膜运输主要由质膜和液泡膜上的离子转运蛋白完成。对质膜和液泡膜跨膜离子转运蛋白包括K+/Na+离子转运蛋白,Na+/H+逆向转运蛋白以及液泡膜H+-PPase的分子生物学研究及应用进展进行了综述。更多还原

【Abstract】 Increased exclusion of Na+ and reduced absorption of Na+ across the plasma membrane as well as vacuolar compartmentation are of critical importance for plant tolerance to salinity.The biochemical effects are accomplished by membrane-bound ion transporters of plasma membrane and vacuolar membrane.This review mainly summarizes the latest research progresses of several membrane-bound ion transporter of plasma membrane and vacuolar membrane such as K+/Na+ transporters,Na+/H+ antiporters and vacuolar H+-PPase at molecular level.更多还原
