Figure 4.

Maximum likelihood phylogenetic reconstruction of Burkholderia species (left) and Psychotria species (right). The Burkholderia tree was reconstructed based on the analysis of a concatenated alignment of 534 true ortholog genes. The reconstruction of the Psychotria plant species was based on a 30 kb chloroplast-conserved fragment. In green are highlighted the leaf nodule bacterial symbionts of Psychotria plant species. The leaf nodule bacterial symbiont of Pavetta plant species is highlighted in blue. Highlighted in red is a symbiont of Riptortus (stinkbug) and in brown, soil isolates. Burkholderia ambifaria AMMD was used as outgroup (not shown). Bootstrap values are shown.
