质膜转运蛋白及其与植物耐盐性关系研究进展

植物细胞质膜有两种主要功能：⑴溶质运输（进出细胞），溶质运输主要由转运蛋白完成；⑵信号传导，即接收信号并引发细胞生理生化响应。盐分过多对植物的伤害主要是离子毒害。质膜转运蛋白活性环境变化能做现迅速响应。本文简要叙述了植物细胞质膜转运蛋白类型、分子特性、生理功能及其活性调节。介绍了植物细胞质膜Ｈ＾＋－ＡＴＰａｓｅ、质膜氧化还原系统、质膜离子载体和离子通道对盐胁迫的响应及其这些响应与植物耐盐性之间的关

Advances in the study on Plasma Membrane-bound Translocating Proteins and Their Relations with Salt Tolerance in Plants

Plant plasma membrane serves two main functions: (1) the transport of solutes (into and out of each cell), which is mainly carried out by the transporters, and (2) signal transduction, i.e., the sensing and initiation of the cellular physiological and biochemical responses. Plasma membrane transporters show rapid changes in catalytic activity in response to changes in the environment. The types, molecular properties, physiological functions and activity regulations of the plasma membrane_bound translocating proteins in plants are briefly reviewed. The responses of plasma membrane H _ATPase, redox system, ion carriers and ion channels in plants to salt stress and the relations of these responses with salt tolerance in plants are described.
