Fig. 3From: Two promoters in the esx-3 gene cluster of Mycobacterium smegmatis respond inversely to different iron concentrations in vitroGrowth curves of the WT, ΔMycP3 mutant and the two complementation strains, ΔMycP3ms::pr1MycP3ms and ΔMycP3ms::pr2MycP3ms under Fe-depleted 7H9 (a), and Fe-depleted Sauton’s media (b). The growth curves were done in triplicate, error bars show standard deviationBack to article page
