Figure 4

Transcript copy numbers/cell quantified by absolute RT-qPCR. Copy numbers ± STABW of crtW148 (grey) and crtZ (black) from E. coli BW-ASTA cultivated in LB or minimal medium (MM) and harvested in late exponential phase are shown. Rha: Induction with L-rhamnose [12 mM]. IPTG: Induction with IPTG [0.5 mM]. * indicates significant transcript number changes between un-induced (LB or MM) and induced state (LB Rha, LB Rha IPTG or MM IPTG, MM Rha IPTG, respectively). p ≤ 0.05, n = 4, unpaired t-test assuming unequal variances.
