Phylogenetic relationships, gene structures and architectures of the conserved protein motifs of the SPL genes from tartary buckwheat. a The phylogenetic tree was constructed based on the full-length sequences of tartary buckwheat SPL proteins using Geneious R11 software. b Exon-intron structures of tartary buckwheat SPL genes. Yellow boxes indicate untranslated 5′- and 3′-regions; blue boxes indicate exons; and black lines indicate introns. The SBP domain is highlighted by a red box. The number indicates the phases of the corresponding introns. c The motif compositions of the tartary buckwheat SPL proteins. The motifs, numbered 1–10, are displayed in different colored boxes. The sequence information for each motif is provided in Table S2. The protein length can be estimated using the scale at the bottom.
