Outline of Final Research Achievements

Effects of ectomycorrhizosphere bacteria on hyphal growth, ectomycorrhizal formation and sporocarps production of an ectomycorrhizal fungus Laccaria parva were examined. Members of Bradyrhizobium that were the most frequently isolated from ectomycorrhizosphere of L. parva in field promoted hyphal extension and sporocarps production of L. parva.

Academic Significance and Societal Importance of the Research Achievements

制御環境下における安定的な外生菌根菌のきのこの発生技術を開発し、野外の菌根周辺に生息する細菌の一部がきのこの発生頻度や成熟度を向上させることを世界で初めて明らかにすることが出来た。本研究成果は、生物間相互作用に関する新知見であるのみならず、栽培が難しいとされる外生菌根菌のきのこの栽培技術開発など応用学問分野の発展にも貢献できる。
