FIG. 2.

Phylogenetic tree of low-G+C-gram positive group constructed by the neighbor-joining method on the basis of 1,245 unambiguously aligned bases. The scale bar represents a 0.02 substitution per nucleotide position. Numbers above and below the branches indicate the percentage bootstrap support out of 1,000 resampling data from neighbor-joining and maximum parsimony methods, respectively (values of <50% are not shown). The sequence from E. coli is used as an outgroup. Accession numbers are indicated in parentheses.
