| Outline of Final Research Achievements |
Ion transport system play an important role in control of the concentration of major ions in plant cells. They contribute to adjust intracellular osmotic pressure and maintain membrane potential by adapting to changes in environmental stress such as dryness, dehydration and salt damage. The transporter functions are involved in the opening and closing of pores responsible for carbon dioxide absorption and transpiration, environmental stress adaptation, and energy conversion of biological membranes. In order to maintain the homeostasis of cells to cope with environmental changes and to regulate the balance of nutrient absorption and excretion in the whole body of the plant, we elucidated the regulatory mechanism of anion channels mediating induction of stomatal closure. This regulation is performed by intracellular kinases, which indicate that intracellular molecules and transporters cooperate to adapt to environmental changes.
