MOESM2 of The evolutionary history of the sucrose synthase gene family in higher plants

Additional file 2: Figure S2. Intron/exon structural organization of angiosperms SUS genes. Blue boxes denote exons within coding regions, and the gray lines connecting them represent introns. Boxes of other colors represent fused exons, and the numbers above them indicate which exons are fused. Red boxes indicate the splitting of the exons. Due to the complexity of the 3′ end of the SUS III subfamily genes, we do not show the fusion of their exons.
