Figure 4From: Escherichia coli avoids high dissolved oxygen stress by activation of SoxRS and manganese-superoxide dismutaseTime course expression of selected genes controlled by SoxRS and OxyR regulons during E. coli growth at 30% and 300% dO 2 . (A) SoxRS controlled genes, (B) OxyR controlled genes, changes in mRNA were analyzed 0, 5, 10, and 40Â min after dO2 shift from 30% to 300% in E. coli MG1655. Error bars represent standard deviations between triplicate analyses.Back to article page
