Abstract:
Addition of multiple repeats of the FS3 upstream activation sequence (FS3-UAS, -270 to -60) intra-molecularly to the TATA containing core-domain of the FS3 (-151 to +31) promoter resulted in 2-3-folds enhanced promoter activity. The chimeric promoter, FS3-UAS-3X with maximum activity, showed 3.31 times stronger activity in root vascular tissue compared to FS3 promoter and could be used efficiently in translational research.
