Unrooted maximum likelihood phylogenetic tree based on concatenated 16S rRNA gene and ITS sequences showing relationships among isolates and type-strains ^(T) of the genus Bradyrhizobium. Bootstrap values were inferred from 500 replicates and are indicated at the tree nodes when ≥50%. GenBank accession numbers are provided in parentheses. The bar represents two estimated substitutions per 100 nucleotide positions.
