FIG. 1.

(A) Phylogenetic tree based on complete acdS gene sequences (1,017 bp) of Burkholderia species and acdS gene partial sequences (785 bp) (indicated by an asterisk). (B) Phylogenetic tree based on 16S rRNA gene sequences (1,310 bp) of Burkholderia species. The trees were constructed using the neighbor-joining method. The nodal robustness of the trees was assessed using 1,000 bootstrap replicates. For both phylogenetic trees the bar indicates 5 nucleotide substitutions per 100 nucleotides. The NCBI GenBank accession number for each strain is shown in parentheses.
