Shifts of arbuscular mycorrhizal fungal functioning along a simulated nitrogen deposition gradient

The deposition of atmospheric nitrogen can significantly boost the amount of nitrogen available in various ecosystems, potentially altering the mutualistic as- sociation between arbuscular mycorrhizal fungi (AMF) and their host plants. Nevertheless, the precise mechanisms and the degree to which externally in- duced nitrogen- related changes in AMF functionality might impact Sorghum bicolor (L.) Moench, a plant known for its high mycorrhizal colonization, re- mains unclear. In this study, the...
