Plasma membrane H-ATPases (PM H-ATPases) are critical proton pumps that export protons from the cytoplasm to the apoplast. The resulting proton gradient and difference in electrical potential energize various secondary active transport events. PM H-ATPases play essential roles in plant growth, development, and stress responses. In this review, we focus on recent studies of the mechanism of PM H-ATPases in response to abiotic stresses in plants, such as salt and high pH, temperature, drought, light, macronutrient deficiency, acidic soil and aluminum stress, as well as heavy metal toxicity. Moreover, we discuss remaining outstanding questions about how PM H-ATPases contribute to abiotic stress responses.
质膜 H+-ATP 酶(PM H-ATPases)是将质子从细胞质输出到质外体的关键质子泵。由此产生的质子梯度和电势差为各种次级主动运输事件提供能量。PM H-ATPases 在植物的生长、发育和应激反应中发挥着重要作用。在这篇综述中,我们重点关注最近关于 PM H-ATPases 对植物非生物胁迫(如盐和高 pH 值、温度、干旱、光照、大量营养元素缺乏、酸性土壤和铝胁迫以及重金属毒性)响应机制的研究,并讨论了关于 PM H-ATPases 如何参与非生物胁迫响应的一些仍未解决的问题。
