Error bars represent the standard deviation from three independent biological replicates. Significant differences between wild-type and Δ<i>rpoN</i> values are indicated (*<i>p</i> ≤ 0.05, **<i>p</i> ≤ 0.01, ***<i>p</i> ≤ 0.001). Note that the <i>y</i>-axis scale differs for first five regions indicated. Underlined genes indicate σ<sup>54</sup> binding sites previously identified by [<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1005552#pgen.1005552.ref014" target="_blank">14</a>].</p>
