Introduction

Both synthetic promoters and transcription factors (TFs) have been powerful components, responsible for precise and exact regulation of specific plant transgene expression. For rational design of minimal synthetic plant promoters, we require specific type, spacing of motifs placed upstream of synthetic promoter and a copy of number. Synthetic transcription factors can be similarly constructed with usage of variety of DNA binding domains (DBs) and efffector domains as well. What makes synthetic promoters and transcription factos better and more efficient than their natural counterparts is ability to provide better and more adequate transgene expression strenght and specificity [1].

Identification of candidate transcription factor binding sites (TFBSs)

All expression data for transcription factors encoding genes was obtained from the Expression Atlas [2].
