Phylogenetic tree highlighting the position of Burkholderia phymatum strain STM815T relative to other type strains within the genus Burkholderia. The 16S rDNA sequences from type strains were obtained from the ribosomal database project , aligned with muscle 3.6, and a neighbor-joining tree was built from a Kimura-2P corrected distance matrix using BioNJ on the www.phylogeny.fr server . Numbers at nodes are % bootstraps from 1000 replicates (shown only if >50%). Accession numbers of 16S rDNA are indicated between parentheses for each strain. C. taiwanensis LMG19424T was used as outgroup.
