| Outline of Final Research Achievements |
In the simultaneous imaging of multiple nuclides using GREI technique, Fe-59, Zn-65 and Cs-137 were absorbed from the root of Lotus japonicus. The results of non-invasive image analysis and quantitative measurement of each tissue had a good correlation and the reliability of gamma-ray imaging is confirmed.
As for the mechanisms of multi-elements accumulation in L. japonicus line B-129, the activity of iron transport from root to shoot was decreased similar to the metal accumulating Arabidopsis, frd3 mutant. However, in B-129, such a loss of iron transport function does not induce the accumulation of multiple elements directly. It was suggested that the mechanisms responsible for the each element transport, not for iron only, are involved in the multi-elements accumulation in B-129.
