Lifespan extension and paraquat resistance in a ubiquinone-deficient Escherichia coli mutant depend on transcription factors ArcA and TdcA


Figure 5. ArcA enhances lifespan and stress resistance through TdcA. (A, B) Survival curves of the shown strains. (C) Survival of the shown strains after a 12-hour incubation with 300 μM paraquat. (D) Expression of arcA relative to rpoA in the strains indicated. The expression of the RNA polymerase encoded by rpoA was similar across the tested strains.
