Modulation of acrR and acrAB expression in strains Ye9N and AR4 by different stressors.

The GFP fluorescence (RFU/OD600) produced by the acrR::gfp (pPRp222) and acrAB::gfp (pPRp269) fusions in Ye9N and AR4 strains are presented. Data shown are mean values ± standard deviation from three independent experiments performed in triplicate. Significance was calculated with Student’s unpaired t-test [ns (non significant)—p>0.05*—p**—p***—pa, c Results for Ye9N strains, grown in LB medium without any stressors, were compared with those for equivalent Ye9N strains, grown in the presence of different stressors.b, d Results for AR4 strains were compared with those for equivalent Ye9N strains grown in the same conditions.Modulation of acrR and acrAB expression in strains Ye9N and AR4 by different stressors.
