Analysis of protein domains, gene structures, and phylogenesis. a Phylogeny of auxin response factor (ARF) proteins between different species. Eleven Carica papaya ARFs (CpARFs), 23 Arabidopsis thaliana ARFs (AtARFs), and 25 Oryza sativa ARFs (OsARFs) are classified into three groups: I, II, and III. Group I includes two subgroups: Ia and Ib. Scale bar 0.1 denotes 0.1 amino-acid substitution per site. b Schematic organization of CpARFs. The ARF domain, B3 DNA binding domain (DBD), and auxin/indole-3-acetic acid (AUX/IAA) family domain are shown in red, yellow, and blue, respectively. c Exon-intron structure analysis of CpARF genes. Exons are represented by blue boxes; introns are represented by gray lines
