Real-time RT-qPCR assays of the selected promoters. a The relative mRNA of gfp controlled by different promoters in S. coelicolor M1146. b The relative mRNA of gfp controlled by different promoters in S. venezuelae WVR2006. c The relative mRNA of gfp controlled by different promoters in S. albus J1074. The values are means  ±  SD from three independent experiments. Data obtained from different growth stages of each strain were not statistically significant
