Outline of Final Research Achievements

In order to comprehensively understand the molecular mechanism related to symbiosis of Mokomotake (plant-fungus symbiont), the following objectives were set. 1) Isolation, structure determination, and elucidation of the mechanism of bioactivity of plant hormone-like substances from the fungus Ustilago esculenta or Makomotake. 2) Searching for the genes whose expressions change during the symbiotic process to comprehensively investigate symbiotic relationships of the plant and the fungus. As a result, we succeeded in obtaining five new compounds from the culture filtrate of the fungus. Their structures were determined by interpretation of NMR, mass spectrometry, and other physicochemical data.
