| Research Abstract |
The nutritional absorption and excretion by plant root systems are one of the most important functions for agriculture; however, they are usually hidden under the ground and hardly analyzed by direct observations.
In this study, novel methods of live imaging and kinetic analysis of absorption / excretion by the root were developed based on current radiotracer imaging technologies such as PETIS. Moreover, some important nutritional features and functions of plant root have been elucidated by using the established methods. For example, cadmium absorption by oilseed rape plants was directly observed using the newly developed root-zone imaging method, and we found that treatment of glutathione, a common tripeptide in a wide variety of organisms, onto the root induces cadmium excretion to the nutrient solution and thus suppresses cadmium uptake to the aboveground parts. These results demonstrated that our new methods are highly promising in the plant and agricultural sciences.
