Soil fungi influence the distribution of microbial functional groups that mediate forest greenhouse gas emissions

► Denitrifying bacteria were positively correlated with fungal biomass in soil. ► Denitrifying bacteria were also positively correlated with soil enzyme activity. ► Methane oxidizing bacteria were negatively correlated with fungal biomass. ► Soil Archaea were negatively correlated with fungal biomass and enzyme activity. ► The distribution of prokaryotic functional groups may be correlated with fungal biomass.
