Effects of different concentrations of PYO on the expression of the P. aeruginosa oxidative stress response genes ahpB and katB

(A) Normalized cDNA levels measured by qRT-PCR. cDNA measurements were normalized by levels of the housekeeping gene oprI (see Methods)(.http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3001093#sec009) (B) Fold change in expression upon PYO treatment, relative to the measurements in untreated Δphz. ahpB: alkyl hydroperoxide reductase B; katB: catalase B. Black horizontal lines mark the mean value for independent biological cultures (n = 3). The data underlying this figure can be found in Table G in S1 Data.(https://journals.plos.org/plosbiology/article/file?type=supplementary&id=info:doi/10.1371/journal.pbio.3001093.s018 )
PYO, pyocyanin; qRT-PCR, quantitative reverse transcriptase PCR.
