Fig. 5B. A phylogenetic tree of bacterial isolates relied on the nucleotide sequences of 16S rRNA genes, constructed by neighbor-joining method.

The scale bar displays the genetic distance. The number presented next to each node displays the percentage bootstrap value of 1000 replicates. The Pseudomonas aeruginosa strain PA0504 was treated as the out-group. The GenBank accession numbers of the bacteria are presented in parentheses.
