Predicted tertiary structures of Gelsemium elegans GeRAV1, Arabidopsis thaliana AtRAV1, and Glycine max GmRAV-01 proteins. The positions of the AP2 domain and the B3 domain were respectively outlined in red dotted lines. The AP2 domain included an α-helix and a β-barrel protein, while the B3 domain included two α-helices (α1 and α2) and a β-barrel protein
