Phylogenetic relationships, gene structures and compositions of the conserved protein motifs of the FtTH genes from tartary buckwheat. a. The phylogenetic tree was constructed based on the full-length sequences of tartary buckwheat trihelix proteins using Geneious R11 software. b. Exon-intron structures of tartary buckwheat trihelix genes. Green boxes indicate untranslated 5′- and 3′-regions; yellow boxes indicate exons, and black lines indicate introns. The trihelix domain is highlighted by a pink box. The number indicates the phases of the corresponding introns. c. The motif compositions of the tartary buckwheat trihelix 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
