Phylogenetic tree showed the phylogenetic position of AHL synthases and transcriptional regulator of strain PD-2. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer from the phylogenetic tree. The horizontal talbar at the bottom represents evolutionary distance as 0.2 change pernucleotide position. The numbers at the nodes indicate the bootstrap values as percentage of 1000 replications. Glucose dehydrogenase enzyme (GI:729809030) from Escherichia coli was chosen as the out group for comparison. a The phylogenetic position of zlaI protein. b The phylogenetic position of zlbI protein. c The phylogenetic position of zlar protein. d The phylogenetic position of zlbr protein
