Fig. 4From: Transcriptionally promiscuous “blurry” promoters in Tc1/mariner transposons allow transcription in distantly related genomesPromoter analysis in yeast cells. Relative promoter activity, expressed as corrected mean RLU values, relative to the positive control (URA3 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 7: Figure S3. The statistical significance of promoter activity against the promoter-less cassette is shown. *P < 0.05; **P < 0.005Back to article page
