  1. Mean (± SD) of sequences, richness (number of SVs) and evenness were calculated for bacteria and fungi. Lowercase and uppercase letters in parenthesis indicated the results of post hoc multiple comparison (Tukey test) among plant species and rhizosheath-root system compartments, respectively. SV sequence variant, H/SV Shannon value divided by total number of sequence variant
