Fig. 1From: The phenotypic, phylogenetic and symbiotic characterization of rhizobia nodulating Lotus sp. in Tunisian arid soils Phylogenetic analysis of Lotus creticus and Lotus pusillus nodule isolates based on the 16S rRNA gene sequences. Analyses were conducted using the Neighbor-Joining method, showing the relationships between isolates and reference rhizobial species. Bootstrap values >50 (using 100 replicates) are indicated at branching points. Bar 0.2 % estimated substitutions. GenBank accession numbers of the new isolates are shown in parenthesesBack to article page
