Dice/UPGMA dendrogram based on the combined CfoI, DdeI, MboI, and MspI 16S rDNA RFLPs and 16S-23S rDNA IGS RFLPs of nodule isolates of endemic woody legumes of the Canary Islands and reference Bradyrhizobium strains (see Table 1). The groupings revealed in this cluster analysis are consistent with both the ARDRA and the IGS PCR-RFLP analyses.
