Maximum likelihood (ML) phylogenetic tree of Burkholderiaceae based on 16S rRNA gene sequences (1329 positions). Bootstrap values ≥ 70% are shown at nodes. The value of the log likelihood was − 12,214.778642. Wolbachia pipientis was used as the outgroup. “T” beside each strain name indicates the strains as ex-type strains. The SakBRE clade consisted of the obtained sequences in this study, indicated by a square with dashed red lines. In the square,16S rRNA gene sequences determined from the DNA templates prepared from BRE-harboring mycelia and pure cultures of the BRE are shown in black and red letters, respectively
