Effects of fungicide treatments on mycorrhizal communities and carbon acquisition in the mixotrophic Pyrola japonica (Ericaceae).

Pyrola japonica, a member of the family Ericaceae, is a mixotroph that grows on forest floors and obtains carbon (C) from both its photosynthesis and its mycorrhizal fungi. Its mycorrhizal community is dominated by Russulaceae. However, the mechanism of its C acquisition and its flexibility are not well understood.

Effect of ectomycorrhizal fungal species on population growth and food preference of a fungivorous nematode.

Fungivorous nematodes can use ectomycorrhizal (ECM) fungi as food resources in forest soils, and they may establish close predator-prey relationships in forest ecosystems. However, the effect of ECM fungal species on the growth of fungivorous nematodes is poorly studied. To identify fungivorous nematode propagation and preference for ECM fungi, we investigated the in vitro population growth and food attraction of the fungivorous nematode Aphelenchoides sp.
