Genes in QT cluster 6 that were identified as being significantly over-expressed in (a) M570 (relA- ppGpp-) relative to M600 (relA+ ppGpp+) during growth on agar plates, are also induced (b) following addition of thiostrepton (THIO) to strain M667 [ΔrelA tipAp::]. In each panel, the x-axis represents time (culture age in (a); time after induction in (b)), and the y-axis is normalized transcript abundance in log10 scale.
