| | Proteobacteria |
| | There are thousands of microbes on the planet, and humans have been studying them for years in terms of their morphology, metabolism, reproduction, and ecology. | | | Although less well studied, other epsilon proteobacteria are also of interest. | | | For instance one has been found to live near hydrothermal vents at the bottom of the ocean. |

| | The theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes). | | | According to this theory, these originated as prokaryotic organisms, which came to live inside eukaryotic cells as endosymbionts. |

| | Do alpha proteobacteria have composite genomes? |
| | We conclude that, within the alpha proteobacteria, genes that are universally present tend to be on the main chromosome and tend to support a consensus phylogeny. | | | Conversely, genes on the smaller replicons or plasmids are often absent from related species and when present they often have a phylogeny different from the consensus. | | | There is little to be gained by horizontal transfer of such genes, and rRNA is part of this basic set, so we might expect the majority of such genes to support the rRNA phylogeny. |
