Characterization of the strengths of the selected endogenous promoters using reporter gene assays in LL3. a Transcriptional level of gfp gene quantified via qPCR under the control of different promoters (rpsU gene was used as internal standard; the transcriptional level of gfp gene controlled by lac promoter was set as 1); b the relative fluorescence intensity of GFP (FI/OD600) under the control of different promoters. Values denote mean ± SD of triplicates
