Figure 7From: Global transcriptional response of Escherichia coli O157:H7 to growth transitions in glucose minimal mediumExpression heat map of 12 genes from the acid fitness region (AFI). Expression values determined from the ANOVA analysis are represented colorimetrically, with dark red representing expression = 3 and dark green representing expression = -4 on a log2 scale. Over half of the AFI genes (7/12) had a significant increase in expression from mid- to late- exponential phaseBack to article page
