Phylogenetic tree showing the position of P. brassicacearum L13-6-12 in relationships among other strains of Pseudomonas spp. including P. aeruginosa PAO1 as outgroup. The tree is based on 16S rRNA gene alignments and was conducted in MEGA6 [41]. Initial tree 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 approach, and then selecting the topology with superior log likelihood value
