FIG. 3.

Phylogenetic relationships of cpcB genes cloned from Daechung Reservoir. The reference sequences were from GenBank. The nucleotide sequences (267 bp from the 3′ end) from cpcB were used for the phylogenetic analysis. cpcB genes with a similarity of more than 95% are grouped. A representative clone from each group is indicated in parentheses. The bar indicates 0.05 substitution per nucleotide position. The local bootstrap probabilities are indicated at the nodes if they are larger than 50%.
