Amino acid compositions of middle region (MR) and classification of the PtrARF proteins. (A) Amino acid contents of the MR of 35 PtrARF proteins. PtrARF proteins are represented in the horizontal axis, and corresponding amino acids are represented in the vertical axis. Colored bars represent different amino acids; (B) the protein structure of PtrARF proteins. DBD, DNA-binding domain; CTD, C-terminal dimerization domain; MR, middle region; RD, repression domain; AD, activation domain; Q, glutamine; S, serine; L, leucine; P, proline; G, glycine.
