Fig. 2From: Genome-wide identification and characterization of auxin response factor (ARF) family genes related to flower and fruit development in papaya (Carica papaya L.)Analysis of amino acid content and classification of Carica papaya auxin response factor (CpARF) proteins. a The protein structure of CpARFs. 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. b Amino-acid content of MR domains in putative CpARFs. CpARF is the X-axis variable and the corresponding amino acid content is the Y-axis variable. Colored bars represent different amino acidsBack to article page
