植物水通道蛋白研究进展

高等植物细胞质膜、液泡膜上存在着丰富的水通道蛋白,它广泛分布于几乎所有器官和组织,并具 有一定的组织特异性。文章介绍了植物水通道蛋白的发现、结构、分类以及近年来在亚细胞定位、基因表达和功能 方面的研究进展,初步探讨了植物水通道蛋冉研究中存在的问题及今后的研究热点。

Advances in the studies on plant aquaporins

Aquaporin belongs to a highly conserved group of membrane proteins called major intrinsic proteins that facilitate water transport across biological membranes. Plant MlPs can be subdivided into the plasma membrane intrinsic protein,tonoplast intrinsic protein,and NOD26-1ike intrinsic protein subfamilies,which are distributed over almost all organs of the plant and tissue-specifically expressed. We introduced the discovery,structure,classification and the latest research progress of the AQP localization, tissue- and cell-specific expression and function. Problems existing in the research and future directions were also discussed.
