摘　　要：植物质膜H+ -ATPase属于P型质子泵。由该酶产生的跨膜电化学梯度是物质跨膜运输的原初动力。质膜H+ -ATPase与植物生长发育密切相关 ,被称为植物细胞的“主宰酶”。本文对质膜的分子结构、活性调节、生理功能。Plant plasma membrane H +-ATPase was a P-type proton pump. The transmembrane electrochemical gradients generated by the enzyme was the primary force the transmembrane transports. Researches indicated that the plasma membrane H +-ATPase plays important roles in the growth and development in plants. It was called the 'master enzyme' in plant cells. In this article the molecular structure, biochemical character, physiological roles, response to stresses and regulatory mechanism in the signal transduction pathway of the plasma membrane H +-ATPase were reviewed.
