arcA is not involved in induction by polymyxin. Fusions in the indicated genes in the WT or arcA background were assayed in the absence (dark bars) or presence (gray bars) of 5 μg/ml polymyxin. Values represent the means ± SDs from at least four separate experiments. All results comparing gene expression in the presence or absence of polymyxin for each strain were statistically different by the Wilcoxon test (P < 0.05).
