The Enterobacteriaceae have β-like motors. (A) An unrooted global flagellar phylogeny. γ-proteobacteria are highlighted in green: the enteric Enterobacteriaceae γ-proteobacteria (Salmonella enterica and Escherichia coli) are not clustered with the other γ-proteobacteria, but are clustered within the β-proteobacteria (purple). Fully annotated version of this tree is presented in Supplementary Figure S1. (B) An organismal phylogeny focused on γ- (green) and β-proteobacteria (purple), rooted with an ε-proteobacterium, Campylobacter jejuni. The Enterobacteriaceae are highlighted in green. Fully annotated version of this tree is presented in Supplementary Figure S4. (C) The flagellar phylogeny of the γ- (green) and β-proteobacteria (purple). Note the shift in position of the Enterobacteriaceae (highlighted in green) from the γ-proteobacterial clade to within the β-proteobacterial clade. Rooted with Campylobacter jejuni. Fully annotated version of this tree is presented in Supplementary Figure S5. (D) The Bordetella bronchiseptica flagellar gene cluster is arranged in one continuous genetic locus.
