a Alpha diversity estimates of bacterial communities from soil (n = 14), rhizosphere (n = 21), root (n = 18), and phycosphere (n = 24) samples from At and Cr grown in CAS soil in the greenhouse. A Kruskal–Wallis test followed by a Dunn’s post hoc was used to assess significant differences among groups (P < 0.05). b, c PCoA of Bray–Curtis dissimilarities (ASV-level) constrained by compartment (22.4% of variance explained; P < 0.001). d Phylogeny of partial 16S rRNA sequences of the most abundant bacterial OTUs found in At roots (n = 120), and Cr phycosphere (n = 141) community profiles. Leaf nodes are colored by taxonomic affiliation (phylum level). The two innermost rings (colored squares) represent abundant OTUs in each compartment. Squares highlighted with a black contour correspond to OTUs for which at least one representative bacterial strain exists in the IRL or IPL culture collections. The two outermost rings (barplots) represent log-transformed relative abundances of each OTU in At root or Cr phycosphere samples. Corresponds to experiment A (Supplementary Fig. 1a and Supplementary Table 1).
