摘　要：

水孔蛋白是介导水分跨膜运输的重要蛋白, 在植物水分吸收与运输、体内水分平衡中起重要作用。植物水孔蛋白的表达受生长发育及外界环境因素的影响。本文综述了水孔蛋白表达的时空和日变化特性等方面的研究进展, 结合非生物逆境综述了外因对水孔蛋白表达的影响, 并从作物栽培管理角度对水孔蛋白的研究进行了展望。

Abstract:

Water transport across cell membranes is facilitated by aquaporins (AQPs). The expression of aquaporins varies rapidly at different developmental stages, and in response to different environmental conditions. The present review focuses on the recent findings concerning the spatial and temporal-specific expression profiles of aquaporins, and adaptive responses of the aquaporin expressions to abiotic stresses.

Key words: aquaporins; water uptake and transport; expression profiles; abiotic stresses
