Phylogenetic tree showing the relationship of Bradyrhizobium sp. WSM1253 (shown in bold print) to other root nodule bacteria based on aligned sequences of a 1,012 bp internal region the 16S rRNA gene. All sites were informative and there were no gap-containing sites. Phylogenetic analyses were performed using MEGA [41], version 5. The tree was built using the Maximum-Likelihood method with the General Time Reversible model [42]. Bootstrap analysis [43] with 500 replicates was performed to assess the support of the clusters. Type strains are indicated with a superscript T. Brackets after the strain name contains a DNA database accession number and/or a GOLD ID (beginning with the prefix G) for a sequencing project registered in GOLD [22]. Published genomes are indicated with an asterisk
