(A) Effects of NaCl and the sst gene on rice rhizosphere soil bacterial Shannon diversity index (one-way ANOVA, n = 6, P < 0.05). (B) Principal-coordinate analysis (PCoA) based on Bray-Curtis dissimilarities showing differences in rhizosphere bacterial community structure under the control and 150 mM NaCl salt conditions (PERMANOVA, n = 6, P < 0.05). (C) Canonical correspondence analysis (CCA) based on the bacterial community compositions of samples under the NaCl condition (Mantel test, n = 6, P < 0.05). (D) The relative abundances of the bacterial phyla.
