Paired effect size analysis of the 20 most abundant OTUs comparing relative abundances of each OTU within the same plant between root and nodule (a), rhizosphere and root (b), and root and leaf (c) compartments. Bacterial genera are on the left and OTU number presented parenthetically. Presented are quintiles (minimum, 25%, median, 75%, maximum) of paired effect size [e.g., nodule − root/(nodule + root)] where a value of 1.0 indicates this OTU is only found in the nodules where as a value of − 1.0 means the genus was only found in the Root. Tests for significant enrichment of OTUs between compartments using Wilcoxon signed-rank tests are presented where significant and indicated with tests statistics and p values
