FIG. 2.

Dice/UPGMA cluster analysis of combined DdeI, HaeIII, and MspI restriction patterns of amplified 16S-23S rDNA IGSs of nodule isolates of endemic woody legumes of the Canary Islands and reference Bradyrhizobium strains (see Table 1). The individual RFLPs are shown as bands defined on the actual restriction fragments. Six genotypes were resolved. Not all groupings are consistent with those obtained by ARDRA.
