Figure 5.
The bacterial root microbiota of A. alpina is similar compared with A. thaliana and Cardamine hirsuta. (a) Constrained principal coordinates analysis (PCoA) based on the Bray–Curtis distances on the 36 samples of the ‘diversification' experiment constrained by sample groups. (b) OTUs enriched on roots of A. alpina, C. hirsuta and A. thaliana. Color-coded in black are root-enriched OTUs (RootOTUs). All enriched OTUs are based on a Bayes moderated t-test, P<0.05 (FDR-corrected). Number in brackets: total number of OTUs enriched in the respective plant species. (c) Pie chart reporting family distribution of 18 shared OTUs based on parametric Tukey's honest significant difference and Bayesian and non-parametric Mann-Whitney statistics.
