Fungal (A) and bacterial (B) genera that were 13C-enriched in sand-filled ingrowth bags after a 13CO2 plant labelling experiment in a grassland soil. Each dot represents the mean excess atom fraction (EAF) of all labeled bacterial ASVs and fungal OTUs, flanked by 90% confidence intervals of 13C EAF for the entire genus. The genera are grouped and colored by phylum. * indicates biotrophic organisms (animal parasitic or plant-pathogenic fungi; predatory bacteria). ~ indicates motile bacterial genera
