Phylogenetic tree highlighting the position of Rhizobium leguminosarum bv. viciae GB30 (shown in blue print) relative to other type and non-type strains in the Rhizobium genus using a 901 bp internal region of the 16S rRNA gene. Bradyrhizobium elkanii ATCC 49852T was used as outgroup. All sites were informative and there were no gap-containing sites. Phylogenetic analyses were performed using MEGA, version 5.05 [36]. The tree was built using the maximum likelihood method with the General Time Reversible model. Bootstrap analysis with 500 replicates was performed to assess the support of the clusters. Type strains are indicated with a superscript T. Strains with a genome sequencing project registered in GOLD [20] are shown in bold and have the GOLD ID mentioned after the strain number, otherwise the NCBI accession number has been provided. Finished genomes are designated with an asterisk
