The ASR1-binding DNA sequence was compared to four different databases using the STAMP program [56]. Columns show the databases used for comparison, the TFs possessing similar binding sites, the statistical E values and the alignments between the ASR1 consensus sequence found in this study (on top) as well as for the other TFs (bottom) for each hit, respectively. Single letter codes for more than one nucleotide at ambiguous positions are the same as recommended in http://www.ncbi.nlm.nih.gov/staff/tao/tools/tool_lettercode.html. All of the computer programs compared both plus and minus strands. ASR1 showed a binding sequence almost identical to the one described for SITEIIATCYTC (AtTCP20).
