Figure 4From: Transcriptome profiling reveals links between ParS/ParR, MexEF-OprN, and quorum sensing in the regulation of adaptation and virulence in Pseudomonas aeruginosaImpact of the ParS/ParR system on quorum sensing. A. Transcript abundance (log10 of RPKM values) of QS systems in wild type PAO1, parS and parR mutants. Data points represent means of three replicates ± standard deviations. Expression levels of lasI, rhlI and pqsA in cultures of wild type PAO1 (B.) and ΔparR (C.) at different cell densities. Bacteria were grown in AB minimal medium + 2% casamino acids and RNA was isolated from cells harvested at six different growth stages (OD600). The relative abundance of lasI (♦), rhlI (●) and pqsA (▲) was estimated based on rpoD transcript quantity in cDNA samples determined by qRT-PCR.Back to article page
