Comparison of conserved flag-2 protein tree and house-keeping protein tree. A ML phylogeny was constructed on the basis of a concatenated alignment of 32 conserved flag-2 proteins (left) as well as on the basis of the house-keeping proteins GyrB, InfB, RecA and RecB (InfB). The final alignments for the flag-2 protein tree and house-keeping proteins comprised of 5800 and 2893 amino acid sites, respectively. The best-fit evolutionary models LG + FI + G4 were used for construction of both phylogenies. Bootstrap values (n = 1000 replicates) are indicated. The strains and branches are coloured according to the family to which each belong
