Phylogenetic relationships, gene structure and architecture of conserved protein motifs in AP2/ERF genes from ginger. a Phylogenetic tree based on the full-length sequences of ginger AP2/ERF proteins using MEGA X software. b Exon-intron structure of ginger AP2/ERF genes. Yellow boxes indicate 5′- and 3′- untranslated regions; green boxes indicate exons;and black lines indicate introns. c Motif composition of ginger AP2/ERF proteins. The motifs, numbers 1-10, are displayed in different colored boxes. The sequence information for each motif is provided in Additional file 3: Fig. S2. The protein length can be estimated using the scale at the bottom. d The AP2 domains are highlighted by green boxes and the B3 domain by pink boxes
