Constrained Principal Coordinate Analysis on the Soil and Barley Bacterial Microbiota

(A) Variation between samples in Bray-Curtis distances constrained by microhabitat (22% of the overall variance; p < 5.00E−2) and (B) by accession (5.7% of the overall variance; p < 5.00E−2). In both panels, triangles correspond to rhizosphere and circles to root samples. The percentage of variation explained by each axis refers to the fraction of the total variance of the data explained by the constrained factor. In (B) soil samples were not included.
