  1. Dissection of signaling cascades in plant response to potassium
    Our unit aims to elucidate the components of plant potassium sensing and deficiency signaling in Arabidopsis using various approaches.
  2. Characterization of potassium/sodium channels in various systems
    Potassium and sodium have similar chemical property that belong to alkali I metal group. In order to understand how seaweeds but not land plants survive in salt water, we are studying differences of sodium channels and potassium channels between algae and dicotyledonous land plants.
  3. Development of new methods for radiocesium remediation and analyses of regulatory components for phytoremediation
    In order to develop efficient phytoremediation system for radioactive cesium in Fukushima area, we aim to develop plants which selectively and more (less) efficiently absorb cesium from contaminated soil. In addition, chemical screenings to elucidate the chemicals which affect cesium uptake in plants has been conducted. From the results obtained, the regulatory components of cesium uptake in plants are being studied.
  4. Development of abiotic stresses tolerance plants
    Abiotic stresses including nutrient deficiency and salt stress result in huge loss of plant growth and crop production. As solving these problems, we aim to develop the abiotic stresses tolerance plants using various approaches including molecular, physiological, and chemical approaches.
