FIG. 3.

Phylogenetic tree of the B. cepacia complex based on the complete recA gene sequence. Multiple sequence alignment was performed on these genes and the published recA sequences from B. pertussis, M. flagellatum, X. campestris, and P. aeruginosa. The phylogenetic tree was rooted with the B. pertussis recA gene. Bootstrapping resampling statistics were applied to the tree (100 data sets), and bootstrap values are shown on each horizontal limb of the tree. The genomovar status of each B. cepacia complex strain is indicated on the right of the figure (the corresponding recA phylogenetic group is shown in brackets).
