FIG. 3.
Dendrogram obtained by UPGMA analysis of AFLP patterns of Senegalese isolates, some representative strains from Brazil, from F. albida, and from Aeschynomene, and the reference strains of Bradyrhizobium. The clusters were delineated at above 50% similarity. The clusters 6, 12, 15, 16, 17, 19, 20, 28, 29, 31, 32, 33, and 34 correspond to previously described AFLP clusters (42). The new groups identified in this study (35 to 48) are in bold.
