Correction to: Transcriptional responses of Escherichia coli during recovery from inorganic or organic mercury exposure

Correction

After publication of the original article [1] the authors noted that the key displayed in Figure 1a was incorrect, as the PMA and HgCl2 conditions had been switched.

The correct information follows below:

MG1655 unexposed condition: blue line

MG1655 + 3μM PMA: green line

MG1655 + 3μM HgCl2: red line.

The revised figure is included with this Correction (Fig 1).

Effects of sub-acute mercury exposure on growth of MG1655. a E. coli K12 MG1655 grown in MOPS minimal medium, unexposed (blue) or exposed to 3 μM HgCl₂ (red) or 3 μM PMA (green) during mid-log phase. Asterisks indicate sampling times for RNA-seq. Error bars are standard error (SEM) of 3 biological replicates for each culture condition. See Additional file 1: Figure S1 for full growth curve. b Significantly differentially expressed genes (DEG) counts (up-regulated or down-regulated) for HgCl₂ and PMA relative to unexposed control culture at each time point
