The mRNA expression levels of pmrB/pmrK in different TSAREC02 mutants. Values on the y axis are relative expression levels (fold change) normalized against levels in the colistin susceptible strain MG1655. * Significant differences compared to those in TSAREC02 (Student’s t-test, P < 0.05). N.D., non-detectable or expression level < 0.01
