| Outline of Final Research Achievements |
To enrich iodine concentration of the crops, and to contribute to the reduction of the radiation damage by promotion of iodine intake for human health, the physiological and genetic researches into the absorption and transportation of iodine in plants. As a result, the rice root had IO3- reduction activity (iodate (IO3-) to iodide (I-), and the activity changed by IO3- and I-treatment. It was suggested that the rice root uptake I- which was reduced from IO3-, I- in the root is oxidized to IO3- as well.
A few mutant tolerant to excess iodine was selected. In addition, after searching for a gene and making a functional analysis on absorption and translocation of iodine in rice plant, a candidate gene concerning nitrate transport, will be associated with localization of I- in root cells.
