Figure 7

Comparison of RNA accumulation in mutants and wild-type by RT-PCR revealed that lesA is regulated by rpfC. RNA was extracted from Xff cells grown in PD3 medium (three flasks/condition; 107–108 cells/mL) at 28 °C and 120 rpm. The 16S rRNA gene was used as an endogenous control. Unpaired t test with Welch’s correction was used for statistical analysis (one-tailed; *p < 0.01).
