qRT-PCR verification of S. flexneri virulence plasmid genes induced under anaerobic growth conditions and the role of FNR in the induction. Strand specific qRT-PCR analysis of S. flexneri M90T virulence genes mRNA levels shown to be induced in RNA-seq analysis. Data were calculated as the n-fold difference relative to polA (2Ct, where ΔCt represents the difference in threshold cycle between the target and control genes). Results are shown in relation to the wild-type 2Ct levels under aerobic conditions (referred to as 1). Values greater than 1 indicate increased transcription under anaerobiosis, while lower than 1 indicate the opposite. Significant differences were detected with the wild-type strain 2Ct levels under aerobic and anaerobic conditions, or wild-type vs. Δfnr 2Ct levels under anaerobiosis were compared. P < 0.05, *; P <0.01, **; n = 4; Mann–Whitney test. Error bars show standard deviation (SD).
