Taxonomic distribution and diversity comparisons in rhizosphere and bulk soil microbiomes. A Mean Shannon’s diversity index across the bulk soil and rhizosphere at each time point. All time points (T1–T13) are arranged in order along the x axis in each panel. The vertical dashed lines in the figure indicate the time points that show significant differences from the control group (P < 0.01). B Relative abundance for the most abundant bacterial phyla. Percent relative abundance of the top 10 most abundant phyla for control, drought, salt, and disease treatments across bulk soil and rhizosphere. C PCoA of Bray Curtis distance for all samples. Red: rhizosphere samples; blue: bulk soil samples. D PCoA of Bray Curtis distance for four treatment of rhizosphere samples colored by time point. Individual time points are represented by distinct colors. E The biomarker taxa listed in descending order of importance to the model accuracy. F Dynamics of the relative abundance of the stress-discriminant biomarker taxa with treatment time.
