Comparison of adeL-adeFGH operon and adeIJK operon expression in DB and R2 deletion mutants and parental strains. Panel A, Fold-change in adeL, adeF, adeG and adeH expression in DB versus DBΔadeFGH, R2 versus R2ΔadeFGH; Black bars, DB; grey bars, R2; vertical stripes, DBΔadeFGH; white bars, R2ΔadeFGH. Panel B, Fold-change in adeI, adeJ and adeK expression in DB versus DBΔadeIJK, and R2 versus R2ΔadeIJK; Black bars, DB; grey bars, R2; horizontal stripes, DBΔadeIJK; white bars, R2ΔadeIJK. Panel C, Fold-change in adeL, adeF, adeG, adeH, adeI, adeJ and adeK expression in DB versus DBΔadeFGH ΔadeIJK, and R2 versus R2ΔadeFGH ΔadeIJK. Black bars, DB; grey bars, R2; horizontal stripes, DBΔadeFGH ΔadeIJK; white bars, R2ΔadeFGH ΔadeIJK. All differences in fold-change in gene expression between the parental strains and deletion mutants were significant (*, p < 0.05; **, p < 0.01).
