Genome wide analysis of W-box element in Arabidopsis thaliana reveals TGAC motif with genes down regulated by heat and salinity.

ABSTRACT: To design, synthetic promoters leading to stress-specific induction of a transgene, the study of cis-regulatory elements is of great importance. Cis-regulatory elements play a major role in regulating the gene expression spatially and temporally at the transcriptional level. The present work focuses on one of the important cis-regulatory element, W-box having TGAC as a core motif which serves as a binding site for the members of the WRKY transcription factor family. In the present study, we have analyzed the occurrence frequency of TGAC core motifs for varying spacer lengths (ranging from 0 to 30 base pairs) across the Arabidopsis thaliana genome in order to determine the biological and functional significance of these conserved sequences. Further, the available microarray data was used to
