Differences in bacterial community composition between phyllosphere, laimosphere, and bare soil surface samples. A Principal component plot (of rCLR transformed data) showing differences between the three sample types (symbol color) and of the seven different T. landbeckii populations (symbol shape). Significant differences between groups of samples were evaluated based on PERMANOVA on a robust Aitchison distance matrix and are listed besides the plot. B Differences in Shannon’s index, evenness, and Faith’s PD. Overall differences were assessed based on Kruskal–Wallis tests, followed by Dunn’s test with Benjamini–Hochberg correction for pairwise comparisons
