From: Chance and necessity in the genome evolution of endosymbiotic bacteria of insects
Genome distribution of genes with strong selective constraints in endosymbiotic bacteria. We identified genes with strong constraints in each of the five endosymbiotic bacterial lineages: (a) Buchera aphidicola (from Acyrthosiphon pisum); (b) Candidatus Blochmannia (Blochmannia floridanus); (c) Blattabacterium from Periplaneta americana; (d) Wigglesworthia glossinidia; and (e) Ca. Baumannia cicadellinicola. Genes indicated in the circle-representation of the endosymbiotic genomes are those that were specifically identified in that endosymbiotic genome and not the others from the same group. These genes are mostly related to the metabolism of the bacterium that interacts with the metabolism of the insect host.
