DREB Genes from Common Bean (Phaseolus vulgaris L.) Show Broad to Specific Abiotic Stress Responses and Distinct Levels of Nucleotide Diversity

Figure 1

Alignment of the AP2 domain of 54 putative DREB proteins from common bean. Position 14^th and 19^th, described as important for protein binding, are separated by spaces along the sequences. Position 14^th presents 100% conservation of the amino acid valine (V), while the 19^th varies, although glutamic acid (E) and leucine (L) are the most frequent. Other sequences than the 54 DREB were compared in the alignment. Those sequences fitted as putative DREB in the phylogenetic analysis, but not for amino acid conservation.
