| Outline of Final Research Achievements |
Cadmium (Cd), harmful heavy metal element, is one of the factors threatening our food safety. To establish a novel cultivation technique is an urgent issue to reduce Cd accumulation in crop plants. In our previous research, we found that glutathione (GSH), which was applied to plant roots site-specifically, inhibited Cd translocation from roots to shoots selectively and reduced Cd accumulation in shoots. Elucidation of molecular mechanisms, which is activated by GSH, is necessary to establish a novel cultivation technique by applying this phenomenon. In this research, we found GSH has no effects on physical process of Cd absorption in roots and more than a certain amount of GSH in root zone is required to trigger inhibition of Cd translocation from roots to shoots. GSH, applied to roots, increased amount of Cd in the apoplast of their roots.
