摘要:

质膜水通道蛋白(PIPs)是一种具有高度保守性的膜蛋白，是水通道蛋白(AQPs)的亚家族之一，有助于水分、CO₂和H₂O₂的跨膜转运，在维持多种非生物胁迫环境下植株的水分平衡方面发挥重要作用。PIPs定位于质膜，通常以四聚体形式发挥作用，在高等植物中拥有丰富的亚型，根据一级结构中C端和N端的序列特征可以分为PIP1、PIP2这2个亚类。植物在盐、干旱、寒冷、淹水等非生物胁迫下，PIPs活性会被细胞内脱落酸(ABA)、Ca²⁺和H₂O₂等信号因子调控，且PIPs可以跟多种胁迫响应蛋白互作，改变质膜通透性，从而促进细胞内H₂O₂外排，维持细胞渗透平衡和植株水势。有研究表明提高转基因植物中PIPs的表达可以提高植物对逆境的抗性，但是某些情况下过表达PIPs会使植物对逆境更敏感，对胁迫的抗性也根据物种、生长阶段和胁迫类型出现多样性。本文综述了PIPs的分类、结构、亚细胞转运、翻译后修饰和门控机制等多种活性调控的分子机制以及应用转基因方法对植物抗逆的影响，以期为增强植物抗逆性提供理论基础。
