Schematic representation of genetic backgrounds of the M. tuberculosis H37Ra and H37Rv strains used in this study. The genetic backgrounds of M. tuberculosis H37Ra and various recombinant derivatives thereof along with the M. tuberculosis H37Rv devR overexpression strain used in this study are presented as a schematic. The site-specific integration of mycobacterial integrative vector pJFR19 is shown at the attB site. The mutation in the phoP coding region in H37Ra is depicted with an asterisk.
