Horizontal gene transfers of two different rhodopsins. a Phylogenetic tree (RAxML, 100 bootstraps) of different rhodopsin types. See Fig. S12 for details of closely related proteo- and xantho-like rhodopsins of Methylophilaceae. b Arrangement and protein similarity of rhodopsins and the retinal biosynthesis gene cluster in “Ca. Methylopumilus spp.”, “Ca. Methylosemipumilus turicensis”, marine OM43, and other freshwater microbes with closely related rhodopsin types
