Comparative measurement of the transcription (complementary DNA [cDNA] abundance) of genes (lsrR, ahpCF, and katG) by RT-qPCR. A The relative lsrR transcript level was determined in WT strain with or without addition 0.5 µL/mL 30% H₂O₂. B The relative ahpC transcript level was determined in strains WT/pUC19 and WT/pUClsrR cultured in LB broth with 100 µg/mL ampicillin. C The relative katG transcript level was determined in strains WT/pUC19 and WT/pUClsrR cultured in LB broth with 100 µg/mL ampicillin. (Error bars indicate SD; ^∗∗P  <  0.01, ^∗∗∗P  <  0.001).
