FIGURE 1

Species-dependent colonization of rhizosphere and root microbiomes in Setaria species. Bacterial OTUs of Setaria italica (orange) and S. viridis (green) were analyzed using Principal Coordinates Analysis (PCoA) plots generated from distance matrices for the Jaccard indices sets. The plot shows the first two principal axes. Rhizosphere (Rh) samples are shown as squares, root external plus root endophytic (REE) samples are shown as circles and root endophytic (REN) samples are shown as triangles. (A) Comparison of the three compartments across both species. (B–D) Figures are comparisons between species of the Rh, REE, and REN compartments individually. Non-parametric AMOVA to find significant differences between S. italica and S. viridis samples for each compartment produced p-values 0.056, 0.001, and 0.001 for Rh, REE, and REN samples, respectively.
