Outline of Final Research Achievements	Mycorrhizal communities associated with roots of Quercus dentata and Quercus crispula were revealed by metabarcoding analysis. Genetic background of the host individuals were also revealed by RAD-seq. Based on those datasets, we found that a principal coordinate axis of genotypic distances among host individuals significantly correlated with community similarity of basidiomycetes and ectomycorrhizal fungi although any axes were not significant in ascomycetes. On the other hand, correlation between fungal community similarity and genotypic distances among hosts was not significant in both basidiomycetes and ascomycetes. Those results suggest that fungal community composition correlate with not merely genotypic similarity of hosts but an element involved in host’s genotype.
