Research Abstract

The extraradical mycelium(EXM) is the origin of functions in ectomycorrhizal symbiosis. In this study, we investigated the diversity and spatial distribution of ectomycorrhzial(ECM) fungal species in forest, and the nutrient translocation within EXM and interactions between EXMs using tracer experiments with Pinus densiflora seedlings. Consequently, we found a high species diversity and clustered distribution of ECM fungi. We also demonstrated that all portions in EXM and sporocarps are strong sinks, and that neighboring EXMs interact and connect each other with thick hyphal bands and enable the nutrients to be translocated freely between them. These results led us to new ideas,"frequent EXM reconstruction" and "ectomycorrhizal guild", in relation to EXM dynamics in forest.
