Arbuscular mycorrhizal inoculation and plant response strongly shape bacterial and eukaryotic soil community trajectories

We assessed the temporal dynamics of the bacterial and eukaryotic soil microbial communities in mesocosms where AM fungi were inoculated on a grass (Holcus lanatus L.) and a clover (Trifolium pratense L.). This allowed us to evaluate whether 1) inoculation with AM fungi changes the overall structure of soil communities and 2) if these changes are partially mediated by the altered plant phenotype, as indicated by increases in growth and photosynthetic activity.
