A. Violin plot of V. cholerae ΔhapR cells expressing the indicated sRNAs (x-axis) plotted as relative fold-repression (y-axis) of secreted CTX protein fractions in comparison with a control strain (pCMW) grown under AKI conditions. Indicated in grey is the only known repressor of CTX to date (VqmR) and indicated in pink is the yet uncharacterized sRNA, Vcr082 (VcdRP).
