Phylogenetic tree of T. halophilus based on concatenated nucleotide sequences of the housekeeping genes (fusA, gyrA, gyrB, lepA, pyrG, recA, rpoD) using the Neighbor-Joining method [49]. The optimal tree with the sum of branch length = 0.10333351 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches [52]. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Maximum Composite Likelihood method [53] and are in the units of the number of base substitutions per site. All positions containing gaps and missing data were eliminated. There were a total of 12057 positions in the final dataset. The strains isolated from lupine moromi are marked in yellow. T. osmophilus DSM23765^T was used as an outgroup
