DNA methylation profile across the 12 kb –long VRN-A1 gene. A. Site by site DNA methylation levels across the VRN-A1 gene. Squares and triangles represent bisulfite and restriction enzymes data, respectively. Red, blue and green colors represent CG, CHG and CHH contexts, respectively. B. Gene structure of the VRN-A1 gene (based on the Genbak accession AY747600). The black box indicated as “Prom” highlights position of the promoter region as described in [41]. Grey boxes represent exons. Dashed frame indicates position of the deletion in the Langdon allele (from alignment comparison with Genbank accession AY747598). Purple lines highlight positions of transposable element sequences, with corresponding class and name indicated below. Brown and pink lines represents the fragments studied using bisulfite-based and restriction enzyme-based techniques, respectively. Corresponding fragment names are given above each line.
