Expression of PW-cat-lacZ (A) and PX-cat-lacZ (B) during growth in liquid culture. Strains containing PW-cat-lacZ and PX-cat-lacZ were grown to T1 and T−2, respectively, and β-Gal levels were determined. Results are normalized to those for wild-type strains, in which the PW-cat-lacZ and PX-cat-lacZ strains produced 28.5 and 30.5 Miller units, respectively. Error bars represent standard deviations from the mean, with n = 2. Note that, in many cases, up-regulation is not apparent in liquid culture, despite obvious effects on plates.
