Effect of ribN deletion on expression of ribB and ribD. Relative ribB and ribD expression in ∆ribN with riboflavin and WT without riboflavin, both strains without riboflavin and ∆ribN and its complemented derivative growing with or without riboflavin as indicated, determined by real time PCR. Media and standard deviation from three independent experiments are shown. RF riboflavin
