Figure 2. Expression and cotranscription of bcrABDR genes in presence of bacitracin.

Figure 2

A) Semi-quantitative RT-PCR analysis of strain c1261_A grown in various concentrations of bacitracin. Expression of 16S rRNA gene (rrn) was used as a control. B) Amplification of intergenic regions by RT-PCR of strain c1261_A grown in presence of 256 µg/mL of bacitracin. Lane L, DNA ladder; Lane 1, bcrA; Lane 2, bcrB; Lane 3, bcrD; Lane 4, bcrR; Lane 5, bcrD/bcrB intergenic region; Lane 6, bcrB/bcrA intergenic region; Lane 7, bcrA/bcrR intergenic region.
