Rhizosphere bacterial communities are shaped by rhizobial inoculant, impacting plant nutrition. A Global percentage of variation in microbial communities explained by the factors studied in this study. B Alpha diversity in rhizosphere bacterial communities. C Dominant rhizosphere bacterial taxa across rhizosphere samples, average relative abundance of taxonomic groups making up > 0.1% of total abundance; each bar is the average of 3 pooled samples of 8 biological replicates. D CCA of beta diversity of rhizosphere bacterial communities in rhizosphere soils from mock and WSM1022 inoculations, with the clusters of soil edaphic factors from Fig. 1B (blue arrows indicate the direction and magnitude (length) of the correlation). E CCA of beta diversity of rhizosphere bacterial communities in rhizosphere soils from mock and WSM1022 inoculation, with the clusters of plant shoot nutrients from Fig. 1C (blue arrows indicate the direction and magnitude (length) of the correlation); for D, E hash symbols denote significant correlation (P < 0.05) permutation test (1000 permutations) of CCA fit by vegan R package. Individual plot points indicate pooled samples of 8 biological replicates
