Table 2 Analysis of similarity (ANOSIM)

From: Structural variability and niche differentiation in the rhizosphere and endosphere bacterial microbiome of field-grown poplar trees

  1. Plant compartment effects on the bacterial community structures were calculated using ANOSIM (analysis of similarities) with the Spearman rank correlation method in Primer 7 (10,000 permutations). Plant compartments (rhizosphere soil, root, stem, leaf) were a priori defined groups at two phylogenetic levels: phylum level and OTU level. Significance levels: *P ≤ 0.01; **P ≤ 0.001; ***P ≤ 0.0001. R, ANOSIM test statistic. Graphical results of ANOSIM are displayed in Additional file 3
