Figure 1

Evolution of the 5' flanking gene order in the Mannheimia genomes analyzed in this study. The organismal cladogram that describes bifurcation order was adapted from Larsen et al. [26]. Colored arrows indicate orthology as in Figure 2. Gene names are those reported in protein databases or have been assigned by us on the basis of orthology relationships. Pseudogenes are indicated by a "Ψ". The two types of genome rearrangements are indicated by circles. Nomenclature: sequence names contain abbreviations of the taxonomic group (genus and species) followed by the corresponding strain ID as listed in Table 1.
