Phylogenetic relationships, gene structure and architecture of the conserved protein motifs in 89 genes from S. italica. (A) The phylogenetic tree was constructed based on the full-length sequences of S. italica MADS-box proteins. (B) Exon–intron structure of S. italica MADS-box genes. Lines represent introns, boxes represent exons, and domains are color-coded. Number indicates the phase of the corresponding intron. (C) Amino acid motifs in the SiMADS-box proteins (1–10) are represented by colored boxes. Black lines indicate relative protein lengths. Sequence information for each motif is provided in Table S2.
