Lifespan extension and paraquat resistance in a ubiquinone-deficient Escherichia coli mutant depend on transcription factors ArcA and TdcA
Figure 1. The ubiG mutant survives longer than wt. (A-C) Survival curves of the indicated strains under the shown conditions. (D) Fraction of surviving cells at 24 hours in stationary phase for wt and the ubiG mutant in the MG1655 genetic background. (E) Growth curves of the shown strains. (F) Survival of wt and the ubiG mutant under normoxia or hypoxia. (G) Survival of the arcA mutant under normoxia or hypoxia.
