Fig. 3.

Phylogenetic relationships, gene structure, and architecture of conserved protein motifs in AP2/ERF genes from sugarcane. The phylogenetic tree was constructed based on the full-length sequences of sugarcane AP2/ERF proteins using MEGA7 software—exon and intron structure of sugarcane AP2/ERF genes. Yellow boxes indicated untranslated 5 - and 3 -regions; green boxes indicated exons; gray lines indicated introns. The AP2 domains were highlighted by red boxes and the B3 domain by light green boxes. The motifs, numbers 1–25, were displayed in different colored boxes. The sequence information for each motif was provided in Additional file 6. The protein and gene length can be estimated using the scale at the bottom
