Fig. 3From: Global transcriptomic response of Escherichia coli to p-coumaric acidShort-term dynamic transcriptional response of selected genes to p-CA. Asterisks over bars indicate time and p-CA concentration that yields a twofold increase in specific fluorescence value. The p-CA was dissolved in absolute ethanol at concentrations corresponding to 0- (control),1.5-, 3-, and 5-mMBack to article page
