Outline of Final Research Achievements

Control of the Intracellular osmolarity of the plant and microorganism is necessary for adaptation of environmental change. The membrane transport of K and Na is indispensable to absorption of nutrients and hormone, circulation, maintenance of membrane potential, and a photosynthesis, which supported plant growth. We have elucidated the control mechanism of the ion translocator which plays the central role of the system to control homeostasis maintenance of K/Na balance in plant cells, the manifested analysis and regulation of the channels, and the molecular construction of mechanosensitive channel in cyanobacteria.
