Figure 4.

Acid residue alignment of WRKY domain. Alignment was performed using DNAMAN. The suffix ‘N’ and ‘C’ indicate the N-terminal WRKY domain and the C-terminal WRKY domain, respectively. The amino acids forming the zinc-finger motif are underlined in black. The conserved heptapeptide is surrounded by red box. The position of a conserved intron was indicated by an arrow head. The color shade of the amino acid residues highlighted the homology level: dark blue = 100%, pink ≥ 75%, and cambridge blue ≥ 50%.
