Community functional differences and functional contributions to vegetation property. (A) Functional redundancy indices (FRIs) of bacterial community in soils with inoculation of phosphate-solubilizing bacteria (PSBs) (Sup + Bac) and soils without addition of PSBs (CK + Tri) soils. A log ratio > 0 denotes that a function is more redundant in soils without PSB addition. (B) Differences in bacterial functions between group with addition of PSBs (Sup + Bac) and group without addition of phosphorus-solubilizing bacteria (CK + Tri) at Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway level 1 and level 2. (C) Effects of functions at KEGG pathway level 2 on vegetation property determined by permutational multivariate analysis of variance (PERMANOVA). The abbreviations of F1–F21 represent functions in panel B (from bottom to up, namely, from amino acid metabolism to replication and repair). Asterisks denote significance (p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001).
