Microbiotas of bx2 and bx6 tend to be more similar to each other than bx1. Compartment-wise Constrained Analysis of Principal Coordinates (CAP) using Bray-Curtis distances of community profiles from bacteria (left) and fungi (right) and from rhizosphere (upper) and root compartment (down) from the Aurora experiment are shown in a. CAPs were performed using the model ‘~ genotype’. Genotypes differ in color with wild-type W22 in yellow, the bx1 mutant in medium, the bx2 mutant in light and the bx6 mutant in dark green. b Number of OTUs that differed significantly between the wild-type line W22 and each mutant (same colors as in a) as determined by edgeR analysis (FDR < 0.05, Table S13). The % cRA represents the cumulated relative abundance of all detected differentially abundant b/fOTUs for the respective statistic contrast term
