Plant Stress Responses

Since plants cannot move, they must cope with various environmental stresses. In our group, we are focusing on “mineral stress” including deficiency of essential nutrients or excess of toxic and essential elements. We are working on the identification of transporters involved in the uptake, root-to-shoot translocation, and distribution/redistribution of different mineral elements mainly in rice, and on the regulatory mechanisms of these transporters in response to environmental changes. Our goal is to improve the productivity and safety of crops through the manipulation of transporters.

Molecular mechanism of transport system of mineral elements

Mineral elements including essential and toxic elements are transported from soil to different organs and tissues in plants, which are mediated by various transporters. However, most transporters have not been fully functionally characterized. We focus on transport systems in rice and are working on three different aspects; 1) identification and functional characterization of unknown transporters, 2) regulation mechanisms of transporters in response to environmental changes, 3) manipulation of useful transporters for better and safe crop production.
