摘　　要：水孔蛋白是植物重要的膜功能蛋白,不仅介导植物各组织间水分的高效转运,还参与植物体内其他物质的跨膜转运,同时在植物光合作用、生长发育、免疫应答以及信号转导等生理过程中也发挥重要作用。本文主要综述了植物水孔蛋白结构特征和分类,多种生理功能,以及其转录水平和转录后水平活性调节等方面的最新研究进展,并就如何系统全面地开展水孔蛋白参与植物生长发育过程的分子调控机制研究提出展望。植物水孔蛋白的深入研究有助于阐明植物体内物质转运的分子机理及其生理作用机制,对指导农业生产中作物的生长发育调控有重要理论意义。Aquaporins are important functional proteins in plants, which not only transport water between different plant tissues but also participate in other nutrient transmembrane movement. Aquaporins also play a significant role in many physiological processes such as photosynthesis, plant growth and development, immune response, and signal transduction. We reviewed recent research progress on the structural features, classification, and physiological functions, as well as transcriptional and post-transcriptional regulation of aquaporins, and provided good study prospects on the processes plant AQPs take part in for plant growth. Detailed research on aquaporins could contribute to a better understanding of the physiological functions and molecular mechanisms of nutrient movement in plants, thus providing a theoretical base for growth and development regulation in crop production.
