Dendrogram of the 16S-23S rRNA gene ITS region of indigenous soybean-nodulating bradyrhizobia and Bradyrhizobium USDA reference strains. The similarity between Bradyrhizobium elkanii USDA 76T and 94 (which was 90%) was applied as the criterion to differentiate the clusters. Clusters are indicated on the right. The diversity index (H′) was calculated using the following equation: H′ = −Σ Pi ln Pi.
