| Outline of Final Research Achievements |
In this study, we show that the Japanese white jelly mushroom, Tremella yokohamensis, has a heterothallic life cycle and a bipolar mating system. When yeast-like cells of the a and α mating types were mixed and cultured on low-salt vegetable juice agar medium, mycelia with clamp cells could be induced, but could not be maintained or grown as mycelia. Tyrosol was purified and identified from culture filtrate of Annulohypoxylon sp.. The mycelia of the Tremella sp. could be induced by Tyrosol secreted by Annulohypoxylon sp. This is the first report of quorum sensing between basidiomycetes and ascomycetus fungi.

| Academic Significance and Societal Importance of the Research Achievements |
日本産シロキクラゲが，ヘテロサリックな生活環であることと二極性の交配型をもつことを明らかにしたことは，本菌の育種技術開発に重要な知見を与えた．また，シロキクラゲのコンパニオン菌であるクロコブタケ属菌が，Tyrosolを生産することを発見し，そのTyrosolが，シロキクラゲの菌糸体を誘導できることを示したことから，子嚢菌と担子菌のQuorum sensingの実例を初めて示すことができ，シロキクラゲの純粋培養による人工栽培への道を切り開くことができたものと考えられる．
