Soil salinity and the resulting salt stress it imposes on crop plants is a major problem for modern agriculture. Understanding how salt tolerance mechanisms in plants are regulated is therefore important. One regulatory mechanism is the APETALA2/Ethylene Responsive Factor (AP2/ERF) transcription factor family, including dehydration responsive element binding (DREB) transcription factors. By binding to DNA, specifically upstream of genes that play roles in salt tolerance pathways, DREB proteins upregulate expression of these genes. DREB in Triticum aestivum (wheat) cluster in sub-groups and in this study by scanning the recently extended predicted proteome of wheat for DREB, we increased the number of members of this sub-family. Using the wheat genome, we identified 576 genes coding for the AP2 domain of which 508 were identified to have one AP2 domain, a characteristic of the DREB/ERF subfamily. We confirmed the existing four sub-groups by sequence-based phylogenetic analyses but also identified 32 new DREB subfamily members, not belonging to any known sub-group. Transcription factor profile inference analysis identified two genes, TraesCS2B02G002700 and TraesCS2D02G015200, being homologous to DREB1A of Arabidopsis thaliana. Based on molecular simulation (25 ns) analysis, TraesCS2B02G002700 with a CCGAC motif was observed to interact very stably with DNA. In silico mutational analysis at the 19th position in the DREB domain of TraesCS2B02G002700-DNA complex indicated this as a stable part for recognizing and forming interaction with DNA. Moreover, six target genes were predicted having an upstream CCGAC motif regulated by TraesCS2B02G002700. Our study provides an overall framework for exploring the transcription factors in plants and identifying e.g. potential salt stress target genes. Communicated by Ramaswamy H. Sarma
