Phylogenetic diversity of Bradyrhizobium strains nodulating Calicotome spinosa in the Northeast of Algeria

Fifty-two slow-growing strains were isolated from root nodules of Calicotome spinosa grown in the Northeast of Algeria and grouped in 24 rep-PCR clusters. One representative strain for each profile was further phylogenetically characterized. The nearly complete 16S rRNA gene sequence indicated that all strains were affiliated to Bradyrhizobium. Multi-Locus Sequence Analysis (MLSA) of the atpD, glnII and recA genes and of the 16S-23S rRNA...
