FIG. 3.

Phylogenetic analysis of nodC genes from isolates nodulating L. tenuis. Aligned sequences of nodC genes that were 800 bp long (positions 286 −1123 of the nodC nucleotide sequence of M. loti MAFF 303099) were used. The tree was constructed by using the neighbor-joining method. The percentages of replicate trees in which the isolates and reference strains clustered together in the bootstrap test (1,000 replicates) are indicated at branch points (only values greater than 50% are shown). The tree is drawn to scale, and the units for the branch lengths are the same as the units for the phylogenetic distances used to infer the phylogenetic tree.
