Abstract
It is well known that the molecular biological approaches using Arabidopsis gave very big impacts on plant sciences. This is also the case of inorganic metabolisms in plant cells. Most membrane transport proteins were found from Arabidopsis and other few model plants. However, we have still possibilities to find new physiological phenomena from many wild plants, because such wild plants are surviving in the ultimate environments.
Recently, we are investigating salt tolerance of cells of mangrove plants, which are surviving in high salt condition, and phosphate metabolisms of algal cells, which are in the very low level of inorganic phosphate. From these materials, we found new physiological mechanisms for inorganic ion metabolisms. In the present paper, I would like to discuss how we approach survival strategies for the environmental adaptation of plants, using classical physiology of wild plants and modern genome sciences.
