Real-time qPCR analysis of the expression profile of HGT1, glucokinase, and citrate synthase at 12 and 48 h in A. niger 20-15, 21-8 and 10142 strain. The 18S rRNA was used as an internal control. Vertical bars represented the mean ± S.D (n = 3). A The relative transcription level of HGT1 at 12 and 48 h in A. niger 20-15, 21-8 and 10142 strain; B The relative transcription level of glucokinase at 12 h and 48 h in A. niger 20-15, 21-8 and 10142 strain; C The relative transcription level of citrate synthase at 12 and 48 h in A. niger 20-15, 21-8 and 10142 strain. The samples at each time-point with different letters differ significantly (abc, P < 0.05)
