Proposed lateral/horizontal gene transfers between Cfl. aurantiacus and other phototrophic bacteria. Proposed gene transfers are shown in double-headed arrows. Genes in Cfl. aurantiacus may have been transferred either to or from other phototrophic bacteria. Genes encoding core antenna complex, type II reaction center (RC), pyruvate/α-ketoglutarate dehydrogenase, Complex I, AcsF and BchE may have been transferred from or to purple bacteria; pyruvate/α-ketoglutarate dehydrogenase, auracyanin and AcsF may have been transferred from or to cyanobacteria. Auracyanin may have been evolved from or to plastocyanin; chlorosomes, pyruvate/α-ketoglutarate synthase, BchE may have been transferred from or to green sulfur bacteria; and pyruvate/α-ketoglutarate synthase and BchE may have been transferred from or to heliobacteria.
