Fig. 3From: Genome-wide identification and evaluation of constitutive promoters in streptomycetesEvaluation of the selected promoters using a GFP reporter. a Fluorescence intensities were determined in S. coelicolor M1146 derivatives with different promoters. b Fluorescence intensities were determined in S. venezuelae WVR2006 derivatives with different promoters. c Fluorescence intensities were determined in S. albus J1074 derivatives with different promoters. “Control” indicates strains with a promoterless GFP reporter. The ermE* promoter was tested in different Streptomyces species for comparison. The values are means ± standard deviation (SD) from three independent experiments. Data obtained from different growth stages of each strain were not statistically significantBack to article page
