An Insight Into the Intraspecific Variation of Biosynthetic Gene Clusters Between Strains ofBurkholderia thailandensisspp.

The present study aimed to investigate the intraspecific variation of biosynthetic gene clusters (BGCs) in different strains of Burkholderia thailandensis in order to guide natural products (NPs) discovery process. Species from the genus Burkholderia are emerging as promising species due to their biosynthetic potential. Through genome-mining strategies, it was able to identify that B. thailandensis strains present major genome variation between chromosomes I and II and the standard. The positioning of BGCs also differs when comparing each chromosome. Classical pathways as well as terpene and bacteriocins were commonly identified to all of them and BGCs related to the production of nonribosomal peptides and polyketides compounds are often noticed. In addition, hybrids BGCs were identified as using large amount of replicon information. Among all species studied, the strain MSMB121 showed greater potential for biosynthesizing novel natural products and after phylogenetic analysis, the likelihood of recognizing sites of novelties was assigned.
