Low host specificity among arctic ectomycorrhizal fungi
Host specificity among ectomycorrhizal (ECM) fungi seems to vary among different habitats, and it is difficult to draw general conclusions across environments. Little is known about the host specificity among arctic ECM fungi. In this study, we investigated the host specificity of root associated fu...
