The membrane transport system is closely involved in the formation of membrane potential and adaptation to the abiotic stress. We aimed the physiological role of the channels and the transporters which mediated Na and/or K permeation across the plasma membrane and thylakoid membrane. There are some difference in Na and K transport system between animal cells and plant cells. We have studied the structure and function of the Na/K transporters and K channels in plant cells and cyanobacteria which are an essential system for the controlling the solute flux across the membrane.

膜转运系统与膜电位的形成和对非生物胁迫的适应密切相关。我们的目标是介导 Na 和/或 K 渗透穿过质膜和类囊体膜的通道和转运蛋白的生理作用。动物细胞和植物细胞之间的Na和K转运系统存在一些差异。我们研究了植物细胞和蓝细菌中 Na/K 转运蛋白和 K 通道的结构和功能，它们是控制跨膜溶质通量的重要系统。
