Effect of slyA on phoP-phoQ expression. Bacterial strains were grown in M63 glycerol minimal medium containing a low concentration (10 μM) of magnesium plus 0.4% PGA plus 1% potato tuber extract to an OD660 of 1.0 before total RNA was harvested. The expression levels of phoP and phoQ in a ΔslyA background were compared to those in the wild type by quantitative reverse transcription-PCR and normalized to the level of expression of the 16S rRNA gene. The results show the means of three replicates. The error bars indicate the standard deviations.
