| Research Abstract |
Objectives of this study were to establish a new methodology to analyze elemental flows between organisms at levels of cell, tissue, and soil ecosystems. At cellular and tissue levels, mycorrhizal systems were used, where localizations of stable isotope tracers were observed by an isotope microscope in resin embedded sections. For soil microbe interactions, a decline of soil born fungus causing white root rot by a hot water treatment was used as a model system. It was shown that soil microbes participated in the fungal death. Methods to analyze bacteria communities of mycosphere, and inoculation tests, proliferation and antifungal tests on fungal hyphae, with a heat treatment were established for bacterial isolates.
