Putative cis-acting elements associated to cell proliferation or auxin and cytokinin response are differentially located upstream of the AtDRTS coding regions.
Map of the relevant cis-acting elements identified in the intergenic regions separating the diverging AtDRTS and AtSFH coding sequences. Proliferation-related elements are marked with red asterisks whereas auxin-related sites are indicated with purple asterisks and the cytokinin-related CPBCSPOR sites are marked with light blue asterisks. The E2F sites found upstream of AtDRTS2 and AtDRTS3 are indicated with red boxes. The map was created using the drawing tool of the RSAT (Regulatory Sequence Analysis Tools) platform (http://www.rsat.eu/).
