(A) Venn analysis of the OTUs that significantly differed in relative abundance between comparisons of Na-HHZ and Na-HHZcas, Na-ZH11 and Na-ZH11cas, and Na-WT and Na-sst plants. (B to D) The relative abundances of the OTUs that were coenriched in the roots of plants with loss of function of SST under salt stress and coexisted in soils of three pairs of plant materials (B), in soils of Na-ZH11 and Na-ZH11cas and Na-WT and Na-sst plant materials (C), and in soils of Na-HHZ and Na-HHZcas and Na-WT and Na-sst plant materials (D) (DESeq2, n = 6, P < 0.05). In panels B to D, different background colors correspond to different components in the Venn diagram.
