摘　　要：土壤盐渍化是一个世界性的资源问题和生态问题,盐分胁迫几乎会影响植物所有重要的生命活动,造成植物的减产或其他不利影响。液泡膜质子泵(H+-ATPase和H+-PPase)在植物细胞的跨膜物质转运、胞内pH值平衡等诸多生理活性方面都发挥关键作用。因此,在植物对环境胁迫的响应过程中,液泡膜质子泵活性的调节对植物的耐盐性具有重要意义。本文结合植物液泡膜H+-ATPase和H+-PPase的分子结构、生理功能及其在盐胁迫下调节机理的研究结果,阐述了植物液泡膜质子泵的生理功能与植物耐盐性的相关性,并对其仍未解决的问题进行了展望。Soil salinization is a worldwide resources and ecological problem,salt stress almost affects all the crucial behavior of plant,leading to productivity reduction or other detrimental effects.Tonoplast proton pump which con-tains H＋-ATPase and H＋-PPase play a vital role in various physiological activities,such as transmembrane transport and adjustment of intracellular pH in plant cell.Therefore,in the process of responding to the environment for plant,the activity regulation of tonoplast proton pump contributes significantly effect to plant salt tolerance.In this review,we introduced the molecular structures and their regulate mechanism under salt stress,the relationship between the physiological function of tonoplast proton pump of plant vacuolar H＋-ATPase and H＋-PPase Furthermore,we also described the correlation between the physiological function of plant tonoplast proton pump and its salt toleranc and prospected for the unresolved prome of it.
