Extended Data Fig. 4: The effects of microbial inoculants on soil bacterial alpha diversity and community structure based on reanalysis of amplicon data.
a, bacterial alpha diversity, including Shannon, Pielou, ACE, Chao, and Richness diversity. Error bars on the columns represent standard errors (SD). Statistical comparisons are assessed through two-tailed Wilcoxon’s rank sum tests. P values are adjusted using the Benjamini–Hochberg false discovery rate (FDR) correction. All dots signify the change in response ratio between the control and microbial inoculant bacterial diversity at 95% confidence intervals (CIs). The number of observations is provided beside each attribute. b, Principal Coordinate Analysis (PCoA) plots depict the Bray-Curtis distance of bacterial communities in CK and microbial inoculant treatments (CK n = 453 vs. microbial inoculant n = 1076) c, Three non-parametric multivariate analyses, including non-parametric multivariate analysis of variance (Adonis), analysis of similarity (ANOSIM), and multi-response permutation procedure (MRPP), consistently support the significant alteration of bacterial community structure by microbial inoculants. P values are adjusted using the Benjamini–Hochberg method with sequentially modified Bonferroni correction. Source data are provided as a Source Data file.
