Summary Prokaryote–eukaryote interactions are primordial, but host selection of its bacterial community remains poorly understood. Because eukaryote evolution affects numerous traits shaping the ecology of their microbiome, we can expect that many evolutionary changes in the former will have the potential to impact on the composition of the latter. Consequently, the more phylogenetically distant the eukaryotic hosts, the more distinct their associated bacterial communities should be. We tested this with plants, by comparing the bacterial communities associated with maize genotypes or other P oaceae. 16S rRNA taxonomic microarray analysis showed that the genetic distance between rhizobacterial communities correlated significantly with the phylogenetic distance (derived from chloroplastic sequences) between P oaceae genotypes. This correlation was also significant when considering specific bacterial populations from all main bacterial divisions, instead of the whole rhizobacterial community. These results indicate that eukaryotic host's evolutionary history can be a significant factor shaping directly the assembly and composition of its associated bacterial compartment.
