Figure 5. Bacterial diversity is correlated with T. triandra total biomass. Alpha diversity (effective number of ASVs) is positively correlated with post harvest T. triandra biomass across all plant compartments, and watering treatments. Soil aridity is denoted by colour (red = high aridity soils, blue = low aridity soils), and soils exposed to sterilisation at the beginning of the trial are shown with point shape (sterilisation = triangles, live = circles).
