Plant compartment drives the composition of the bacterial communities at the OTU level. a Principle component analysis (PCA) of square-root transformed samples based on rarefaction to 2000 reads per sample. OTUs were defined at a 97% sequence similarity cut-off in mothur. OTUs differentiating the plant compartments are displayed as vectors on the PCA plots. b Hierarchical clustering (group average linkage) of the samples based on Bray–Curtis dissimilarity. Similarities based on Bray–Curtis (b) were superimposed on the PCA plot. PCA and hierarchical clusters were based on 15 biological replicates (rhizosphere soil and root samples) and 11 biological replicates (stem and leaf samples) and were constructed in PRIMER 7 with 10,000 iterations
