摘　　要：植物细胞膜H+-ATPase是初级转运蛋白,它在养分离子跨膜运输、胞内pH调节、细胞伸长生长、气孔开闭,以及植物适应所处的环境与发育过程等生命活动中起着重要的作用。综述了植物细胞膜H+-ATPase在酶活性、基因表达水平以及蛋白水平等方面对不同环境因子及逆境胁迫的适应性;指出分离鉴定、信号传导H+-ATPase等将是进一步的研究方向。In plants, the plasma membrane H^＋-ATPase acts as a primary protein transporter and plays an important role in the transmembrane transport of mineral nutrients, intracellular pH regulation, cell elongation and expassion, stoma opening, and the adaptation of plant to different habitats. The adaptation of plant plasma membrane H^＋-ATPase activity, gene expression and protein content to different environmental factors and adverse stresses were reviewed. The further research direction such as separation and property and signal transduction of H^＋-ATPase were held.
