Luminescence production by the pYR plasmids in the presence or absence of Tc derivatives. A) Luminescence produced by pYR, pYR tetO and pYR tetOR harboring cells. B) Degree of repression by TetR at various arabinose concentrations. TetR expression levels are indicated by an anti-TetR western blot on top of the plot. C) Induction of TetR in pYR tetOR bearing cells at different concentrations of Tc and Atc in the absence of arabinose. D) TetR induction in pYR tetOR bearing cells induced by different concentrations of Atc, Dox and ClTc in 0.02% arabinose.
