FIG. 7.

Phylogenetic relationship between a partial sequence of the cbbL gene from strain MLHE-1 and sequences from representative isolates. The neighbor-joining tree is unrooted and is based on analysis of 744 bp of nucleotide sequence. The accession numbers of sequences used to construct the tree, the phylogenetic affiliations of the isolates (16S rRNA genes), and the BLAST (1) similarity of the MLHE-1 gene to the isolate gene are given in parentheses. The scale bar indicates an evolutionary distance of 0.1, and numbers at branch points indicate bootstrap support as in Fig. 6.
