质膜H^(+)-ATPase影响植物生长发育及逆境响应研究进展

Research progress of plasma membrane H^(+)-ATPase functioned in plant growth and development and its response to abiotic stress

H^(+)-ATPase作为植物生命活动的“主宰酶”,在植物许多生命活动中发挥重要作用。一般情况下,质膜H^(+)-ATPase通过排出质子产生电化学势梯度,水解ATP释放能量应用于植物的生长发育及抗逆响应。鉴于质膜H^(+)-ATPase在植物生长发育和逆境胁迫响应过程中的作用,本文综述了质膜H^(+)-ATPase结构、生理功能及其对植物生长发育的影响,讨论逆境胁迫下质膜H^(+)-ATPase的变化特征及其调节途径,为充分利用质膜H^(+)-ATPase提高水稻等作物产量品质提供重要参考。

As the“master enzyme”of plant life activities,H+-ATPase plays an important regulatory role in many plant life activities.In general,plasma membrane H^(+)-ATPase generates an electrochemical potential gradient by excreting protons,and hydrolyzes ATP to release energy for plant growth and development and stress response.In view of the role of plasma membrane H^(+)-ATPase in plant growth and development and stress response,the structure and physiological function of plasma membrane H^(+)-ATPase and its effect on plant growth and development were reviewed in this paper.The variation characteristics and regulation pathways of plasma membrane H^(+)-ATPase under stress were discussed,which provided an important reference for making full use of plasma membrane H^(+)-ATPase to improve the yield and quality of rice and other crops.
