Figure S2.A full 16S rRNA maximum-likelihood phylogeny of the genus Burkholderia. Similar groupings were recovered following analysis of the data using Bayesian Inference (BI). Statistical support of 60% for ML bootstrap (BS) and 0.60 BI posterior probability (PP) are indicated at the branches in the order PP/BS. Diazotrophic Burkholderia species appear in blue, nodulating isolates in red and all nodulating South African isolates in green, with those isolates from this study also appearing in bold. All strain/isolate designations are followed by the name of the legume host and country of geographic origin. The names of the indigenous hosts are abbreviated as in Table 1. The GenBank accession numbers for the 16S rRNA sequences are listed in Supporting Table S1. The scale bar indicates the number of nucleotide substitutions per site. The outgroups for this tree were Pandoraea apista and Pandoraeanorimbergensis. Please note that although some isolates of B. caribensis and B. fungorum are able to nodulate certain Mimosa species and Phaseolusvulgaris respectively, the type strains has not been shown to be capable of nodulation and/or nitrogen-fixation.
