Genetically induced titration of PdhR in a pdhR mutant reintroduced lag commensurate with expression level for a given TI feedrate (f = 0.38 mmol/g/h). Induction level corresponds to the amount of doxycycline (max - 50 ng/uL, half - 10 ng/uL, and zero 0 ng/uL) added at the onset of starvation. The TI feedrate is abbreviated as f (units: mmol glucose/g dry cell weight/hour). Wild-type lag (from Figure 2A empirical fit) is indicated by the dotted grey line. Lag time reduced with synthesis levels of titrated FtsZ in the wild-type strain at f = 0.31-0.32 mmol/g/h. Lag time increased with titrated synthesis of ClpX in wild-type cells at f = 0.43-0.45 mmol/g/h
