Gene expression analysis of mycP 3 in WTms, ΔMycP3ms, ΔMycP3ms::Pr1MycP3, and ΔMycP3ms::Pr2MycP3 strains under normal 7H9 (iron rich), Fe-free 7H9, and Fe-rescued 7H9 media. The results were normalized against the RNA copy number of sigA. The p values obtained using two-way ANOVA statistical analysis (n = 3) (*p < 0.05, **p < 0.01, ***p < 0.001, non-significant comparison is not shown)
