発表題目	The Relationship between Soil Fungal Communities and Growth of Three Betula ermanii Populations in Five Planting Sites The Relationship between Soil Fungal Communities and Growth of Three Betula ermanii Populations in Five Planting Sites
要旨本文	Global warming is predicted to reduce the resilience of forest ecosystems as plant species migrate northward and upward resulting in species range shifts. Both abiotic and biotic factors can influence migration and adaptation of plant species, but the roles of soil fungal communities have been poorly explored. Here, we investigated soil fungal communities for three Betula ermanii populations in five planting sites of different environments using DNA metabarcoding. Soil fungal communities varied significantly among sites and showed significant relationships with growth, leaf area, climate conditions, and soil properties. Smaller leaf area had a higher proportion of ectomycorrhizal taxa (e.g., Inocybaceae), while larger leaf area had a higher proportion of potentially plant pathogenic taxa (e.g., Nectriaceae). We will discuss the interaction between guild composition of soil fungi and B. ermanii phenotypes.
