Deletion of hapX Causes Deregulation of Genes Involved in Iron Use.

Quantitative real-time RT-PCR analysis was performed in the indicated strains grown as described in Figure 2. Transcript levels of cycA, acoA, lysF, and hemA genes are expressed relative to those of the wild-type (wt) strain grown under iron-replete conditions. Bars represent se from three independent experiments with three technical replicates each. Values with the same letter are not significantly different according to the Mann-Whitney test (P = 0.05).
