  1. Faiths’ phylogenetic distance per SV (PD/SV), net relatedness index (NRI) and nearest taxon index (NTI) have been used as metrics to evaluate bacterial and fungal alpha phylogenetic diversities. Lowercase in parenthesis indicated the results of post hoc multiple comparison (Newman-Keuls test) among plant species
  2. *Communities that are significantly structured at the p < 0.05 level
