FIGURE 3.

Sequence alignments of AP2 domains of representative ERF proteins in S. caninervis and Arabidopsis. Twenty-two AtERF genes representative of each ERF subfamily/group were aligned with ScERFs. The subfamily and corresponding group for each representative AtERFs is depicted on the left. The locus names of AtERFs were marked in blue, and the unigene numbers of ScERFs were labeled with a dark color. The black and light gray shading indicate identical and conserved amino acid residues. The complete conserved amino acids residues of AtERFs and ScERFs were labeled with an asterisk. The three β-sheets regions and α-helix region were labeled.
