RNA maps of the flanking regions of the mexEF-oprN (A) or parI (B) gene on the KT2440 chromosome. Blue, red, and green bars represent the signal intensities of each probe detected in the RNA maps of KT2440, KT2440(pCAR1), and KT2440(pCAR1Δpmr) with the two biological replicates (Replicate-1 and -2), respectively. Pentagons indicate the directions and locations of annotated genes.
