摘　　要：V-ATPase存在于所有已知的真核生物中,在植物的生长、发育、信号转导和胁迫适应过程中发挥着重要的作用.近年来对V_ATPase的结构、功能和调节机制的研究进展较快,V_ATPase主要亚基已经完成序列测定及分析,并对各亚基生理功能、V_ATPase全酶复合体的组装、调控也有了较为深入的研究.该文在阐述植物细胞液泡膜H+_ATPase的基本结构的基础上,介绍V-ATPase亚基组成、编码基因及在胁迫应答中的响应.V-ATPases are found in all eukaryotic cells.an play a very important role in plant growth, development, signalling and stress adaptation. The structure, functions and regulation of V-ATPases have been well studied recently. The amino acid sequences of the main subunits have been determined, and the functions of some subunits, the biosynthesis, assembly and regulation of V-ATPases are also well known now. The structure of the V-ATPase is described in this review, and the subtmits of V-H^＋ -ATPase, the genes and its responses to stress are discussed in detail.
