Figure 1.

Neighbor-joining tree based on concatenated sequences for 645 protein coding genes. Strains that were sequenced in other studies are in bold font and type strains are in italic font. Support for splits was assessed using 1,000 bootstraps, and splits with less than 60% support were collapsed to polytomies. For clarity, the bootstrap values are only shown for the deep branches. Bar indicates number of substitutions per site.
