Fig. 3From: Transcriptionally promiscuous “blurry” promoters in Tc1/mariner transposons allow transcription in distantly related genomesPromoter analysis in S2R+ cells. Relative promoter activity, expressed as corrected mean RLU values, relative to the positive control (copia promoter, set to 100) and to the promoter-less construct (set to 0). Promoters with activity significantly different from the promoter-less reporter cassette are marked with an asterisk. Actual values of each experiment set are shown in Additional file 6: Figure S2. The statistical significance of promoter activity against the promoter-less cassette is shown. **P < 0.005; ***P < 0.001Back to article page
