Outline of Final Research Achievements

A group of molecules has been discovered in mushrooms that put an end to the mystery of fairy rings, an unexplained life phenomenon that has been reported as "fairies dancing in a circle. In this study, it has been shown that co-cultivation of Lepista sordida and bentgrass promotes the growth of both. Therefore, we first used RNA-seq to analyze the genes whose expression was altered in shiva upon co-cultivation with L. sordida with the aim of identifying the genes involved in the promotion of shiva growth. It has also been shown that the expression of nitric oxide synthase (NOS) genes increases under conditions of high production of fairy chemicals.

Academic Significance and Societal Importance of the Research Achievements

キノコに関わるホルモンあるいは作用機構を明らかにできれば、天然物化学・基礎生物学等における学術的成果は極めて大きい（Nature，Science に掲載可能）。また、キノコの発生を人為的に制御（一日当たりのキノコ発生量を制御）することは現時点では不可能である。キノコの発生を自由に促進あるいは抑制することができれば商業的キノコ栽培に対する貢献は大きい。加えて、これまで不可能であったトリュフやマツタケの人工栽培への道を開き、産業、社会に与えるインパクトも極めて大きい。
