| Outline of Final Research Achievements |
To understand ion movement in plants, we have been developing an live imaging system using radioisotopes. Each ion moves via xylem and phloem in plants. To understand ion transport mechanisms in plants, it is important to study xylem and phloem flow separately. So we tried to visualize only xylem flow using heat girdling treatment. The results show that magnesium was transported mainly via the xylem, while the phloem contribution is scarce. On the other hand, phosphate transport via the phloem was slower than via the xylem.
As a second step, we tried to visualize only xylem flow in rice in dark conditions. Magnesium and calcium transport are not influenced by light. On the other hand, phosphate transport in shoot was sensitively influenced by light. This results show that phosphate was transported via the xylem and phloem. On the other hand, the phloem contributions of magnesium, potassium, calcium, and cesium are scarce.
