Different SNPs (synonymous and non-synonymous) in the <i>efpR</i> gene reduce the <i>efpR</i> gene expression during growth in minimal medium.

<p>Bacteria were grown in minimal medium supplemented with D-glucose (20 mM). Bacteria were harvested for total RNA extraction at OD_600nm ~ 0.5 and <i>efpR</i> mRNA were quantified using a qRT-PCR approach. Three biological repeats were conducted for each strain (two for the strain <i>efpR</i>^P96Q). Bars indicate standard deviation (Welch t-test, comparison with the WT strain, * <i>p</i>-value <0.05, **<i>p</i>-value <0.01).
