Fold change in Stx2f mRNA expression in the induced state relative to the basal state. The dotted red line indicates one-fold level. Levels of stx2f mRNA expression were normalized against gapA. Non-induced stx2f mRNA levels of each strain were used as calibrators (defined as 1). Data are represented by mean ± SD (standard deviation) (n = 3).
