To better understand the interaction of arbuscular mycorrhiza (AM) and ectomycorrhizal (EcM) plants during vegetation transition, we studied the reciprocal effects of these species’ coexistence on their root-associated fungi (RAF). We collected root and soil samples from three different microenvironments: stand of AM plant, under EcM plant canopy, and contact zone where roots of the two species interacted. Although the microenvironment significantly affected composition of the RAF communities in both plant species, the effect was greater in the case of AM RAF communities than in that of EcM RAF communities. The presence of EcM plant also significantly decreased AM fungal abundance in soil as well as AM colonization and richness of AM fungi in AM host plant roots.
