Fig. 1: Statistics for adelgid endosymbiont genomes (main chromosomes) sequenced from each major Adelgidae lineage.

A. Relationships of adelgid species representing the five conifer-host-associated lineages, B Chromosome sizes of symbionts (with names indicated at the base of the figure). Circles representing symbiont chromosomes are scaled to indicate size and colored to indicate bacterial lineage (see Fig. 2), C Numbers of predicted open-reading frames (ORFs). The proportion of hypothetical proteins composing the proteome is shown in green, D Numbers of predicted pseudogenes, E The proportion of nucleotides in each symbiont chromosome encoding genes (coding density), F The percentage of G or C nucleotides in symbiont chromosomes.
