FIG 3.
Deletion of xerC increases pyocin gene expression. (A) Representative transcriptional profile of a P07990-lux reporter (reporting on R/F pyocin gene transcription) during growth in LB-Lennox by wild-type PA14 (MTC2280), Δ69700 (MTC2281), or ΔxerC (MTC2297) strains. (B) Representative transcriptional profile as in panel B of wild-type PA14 or ΔxerC strains treated with 0.06 μg/mL ciprofloxacin. (C) Growth curves from the experiment reported in panel B. Error bars show standard deviations for at least three technical replicates; some error bars are smaller than the graph symbols.
