The transcription of key genes involved in carbohydrate metabolism and rifamycin SV biosynthesis after multiple-time point glucose supplementation

(A) The expressions of genes involved in carbohydrate metabolism. (B) The expressions of genes involved in rifamycin SV biosynthesis. The results showed transcription at 12 h and 24 h with or without glucose supplementation, ‘+’ means adding glucose, the time zero point of sugar addition was used for comparison. The legend shows the time after the first sugar supplementation (48 h), rpoB is used as the reference gene. Error bars represent standard deviations of three biological replicates.
