Fig 3. 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. b, Hierarchical clustering (group average linkage) of the samples based on Weighted Unifrac. PCA and hierarchical clusters were based on 3 biological replicates (rhizosphere soil, non-rhizosphere soil and root samples) and were constructed in PRIMER 7 with 10,000 iterations (The code in the figure is shown in Table 1; 01, 02, and 03 are biological repetitions).
