Figure. Unrooted phylogenetic tree based on 16S rRNA gene sequences of Roseomonas spp. Tree was constructed by using MEGA 4.0 software (www.megasoftware.net) and the neighbor-joining method with 1,000 bootstrap replicates. Genetic distances were calculated by using the Kimura 2-parameter correction at the nucleotide level. Bootstrap values >50% are shown. The isolate obtained in this study is shown in boldface. GenBank accession numbers of reference strains are marked after each strain name. Scale bar indicates nucleotide substitutions per site.
