Research Outline

    Potassium and nitrogen are major nutrients for plant growth, and lack of them has entailed increased use of fertilizers. However, increased fertilizer usage does not result in comparable production increase, and excess fertilizer run-off creates soil pollution. Growing ecological awareness necessitates new solutions to increase agricultural production without endangering the environment, and achieve food security via sustainable agriculture. As solutions to these issues, we aim to elucidate the components of plant potassium sensing and deficiency signaling in Arabidopsis using various approaches and develop rice plants that grow well under nitrogen-limited conditions and efficiently utilize other macronutrients. In addition, to establish a new method of phytoremediation, chemical screenings to elucidate the chemicals which affect cesium uptake in plants have been conducted. We are also intensively analyzing regulatory components of cesium uptake that selectively inhibit/suppress/prevent uptake of radiocesium from contaminated soil.
