Figure 8From: Global transcriptional response of Escherichia coli O157:H7 to growth transitions in glucose minimal mediumRelative changes in expression of Shiga toxin genes. Changes in expression of the phage-encoded toxin genes stx1A, stx2A, and stx2B as determined by Q-PCR. Average changes in expression for 2 independent replicate cultures were determined relative to the transcript level of each ORF at the 3 h mid-exponential phase time point.Back to article page
