Figure 2From: Phylogenetics and evolution of Su(var)3-9 SET genes in land plants: rapid diversification in structure and functionSchematic representation of the Su(var)3-9 SET gene structures in PreSET and SET domain regions. Boxes represent exons and lines represent introns. Length of exons are roughly at scale but introns not. Dark gray regions encode for SET domains; light gray regions encode for PreSET domains. The numbers above boxes are the length of exons (bp). The numbers above lines are the intron positions (see Additional file 5 for the alignment of mRNA sequences) and those below are the intron phases.Back to article page
