    Abstract

    Fungal communities associated with plant tissues were compared between two bryophyte species dominating decaying logs (Scapania bolanderi and Pleurozium schreberi), and roots of spruce seedlings growing on the bryophytes and in the ground soil, to evaluate the contribution of fungal communities to seedling regeneration. Using high-throughput DNA sequencing, a total of 1233 fungal operational taxonomic units (OTUs) were detected. Saprotrophic Ascomycota were dominant in bryophytes, whereas ectomycorrhizal (ECM) Basidiomycota were dominant in spruce roots. Fungal communities were significantly different between the two bryophyte species. In addition, fungal communities of spruce seedlings were significantly affected by the substrates on which they were growing. Some ECM fungi were detected from both of the bryophytes and the spruce seedlings growing on them; however, the dominant OTU identities differed between the two bryophyte systems. The possible effects of functional differences between dominant fungal OTUs on spruce seedling regeneration are discussed.
