Fig. 2: Phylogenetic relationships of adelgid endosymbionts within each major Adelgidae lineage.

A Multi-gene Bayesian phylogeny of the Enterobacterales with 158 taxa inferred from 70 orthologs recoded under the Dayhoff-6 scheme. Colors indicate clades of taxa at the family level to which adelgid symbionts belong, B–F Maximum likelihood (shown) and Bayesian phylogenies of individual clades in which adelgid symbionts clustered in (A) using orthogroups where all taxa were represented, G Multigene maximum likelihood (shown) and Bayesian phylogeny of the Burkholderiales. H. Bayesian 16 S rRNA gene phylogeny of the Serratia symbiotica clade; Serratia symbiotica from aphid species are denoted by aphid species names. Adelgid symbiont names are shown in red. Support values are listed as bootstrap replicates supporting nodes for maximum likelihood trees (ML) and percentage posterior probabilities for Bayesian inference phylogenies (BI). Bayesian support values are from analyses conducted on Dayhoff-6-recoded datasets, except for C, where sequences were left uncoded.
