Research progress in plant aquaporins

摘要: 植物所有的生长发育过程都与水分传导息息相关,而植物水通道蛋白(AQPs)在维持植物体内水分平衡中有着重要意义。植物水通道蛋白通过改变质膜的水分渗透性促进了水在细胞间的流动。植物水通道蛋白不仅是水选择性通道蛋白,同时还具有许多生理生化功能,是一类多功能蛋白。它在水分及其他物质运输、细胞伸长与分化、气孔运动等生理过程中均扮演着重要角色。植物水通道蛋白基因在植物所有的组织中都能够表达,有些是受环境因子或激素诱导表达的,还有一些是植物组织或器官特异表达的。从结构、生理功能和基因表达等方面综述了植物水通道蛋白研究领域最新进展。参52Abstract: The entire growth and development process of plants are closely related to water conduction, and the aquaporins (AQPs) are significant in maintaining water balance of plants. AQPs promote the water flow among cells by changing the water permeability of plasma membrane. AQPs are not only the water selective channel proteins but also a type of multifunctional proteins which have many other physiological functions. AQPs play important roles in the physiological processes including transport of water and other substance, cell elongation and differentiation, stomatal movement. AQP genes can be expressed in all plant tissues: some expressions are induced by environmental factors or phytohormones; and others are organ specific expression or tissue specific expression. This paper reviewed the research advances in the structure, physiological function and gene expression of plant AQPs. [Ch, 52 ref.]
