Outline of Final Research Achievements

Tricholoma matsutake is a basidiomycete with edible fruit bodies known as matsutake in Japanese. Matsutake is one of the highest grades of edible mushrooms in Japan. Colony morphology of T. matsutake is known to be influenced by the compositions of media used, while substances inducing the phenomena have yet to be found. We have found Zn2+ regulates colony morphology of T. matsutake. Colony thickening and aerial hyphae formation have been observed at more than 1 μM of Zn2+. No such morphological changes have been confirmed even when other nutritional ingredients provided sufficiently. These findings imply Zn2+ is a key factor initiating colony morphogenesis of T. matsutake.
