The comparison of the intracellular iron levels in WT_ms, ΔMycP3_ms, ΔMycP3_ms::pr1MycP3_ms and ΔMycP3_ms::pr2MycP3_ms strains under 7H9, Fe-depleted 7H9 and Fe rescued 7H9 media. The error bars show standard error of the mean (n = 4). The p values obtained using two-way ANOVA statistical analysis between different culturing conditions for all four strains are smaller than 0.0001 (***), an example is shown for the WT_ms
