From: The MetJ regulon in gammaproteobacteria determined by comparative genomics methods
Phylogenetic tree of the gammaproteobacteria. Species with MetJ homologs are color-coded by order: Alt, Alteromonadales (green); Aer, Aeromonadales (blue); Vib, Vibrionales (purple); Pas, Pasteurellales (red); Ent, Enterobacteriales (orange for symbiotes, yellow for the rest). Selected other species are show in black. Three species marked with an asterisk were assigned to Alt but do not cluster with other Alt species.
