Phylogenetic relationships, gene structures and compositions of the conserved protein motifs of the FtbZIP genes from tartary buckwheat. a The phylogenetic tree was constructed based on the full-length sequences of tartary buckwheat bZIP proteins. b Exon-intron structures of the tartary buckwheat bZIP genes. Green boxes indicate untranslated 5′- and 3′-regions; yellow boxes indicate exons; and black lines indicate introns. The bZIP domain is highlighted by a pink box. The number indicates the phases of the corresponding introns. c The motif compositions of the tartary buckwheat bZIP proteins. The motifs, numbered 1–10, are displayed in different colored boxes. The sequence information for each motif is provided in Additional file 2: Table S2. The protein length can be estimated using the scale at the bottom
