Molecular Phylogenetic analysis by Maximum Likelihood method of the aptD gene. The evolutionary history was inferred by using the Maximum Likelihood method based on the Tamura-Nei model [19]. A Phylogenetic tree highlighting the position of Bosea sp. WAO relative to the other Bosea spp. and related organisms based on the aptD gene. The tree with the highest log likelihood (− 2412.0185) is shown. The percentage of trees in which the associated taxa clustered together is shown next to the branches. Initial tree(s) for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using the Maximum Composite Likelihood (MCL) approach, and then selecting the topology with superior log likelihood value. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 18 nucleotide sequences. All positions containing gaps and missing data were eliminated. There were a total of 361 positions in the final dataset. Evolutionary analyses were conducted in MEGA7 [20]. Type strains are indicated with a superscript T
