| Research Abstract |
Growing interests in food safety make it an urgent issue to establish a new technique to reduce cadmium (Cd), which is one of harmful heavy metal elements, in crop plants. In our research, we found that glutathione (GSH), which was applied to plant roots site-specifically, inhibited Cd translocation from roots to shoots and Cd accumulation in their shoots. It is expected to establish a novel cultivation technique by applying this phenomenon and carrying out some research for practical use. In this research, we tried to elucidate the molecular mechanism of this phenomenon. We found one of the causes for this phenomenon was that glutathione, applied to roots, activated Cd efflux from their roots.
