Validation results of promoter region of Os04g0431700 gene by traditional bisulfite sequencing. In each panel, the top histogram shows the validation results from traditional bisulfite sequencing and the bottom shows the BS-Seq results. Methylation level of individual cytosine sites located on the genome (indicated on the x-axis) is shown on the y-axis. (a) CG context. (b) CHG context. (c) CHH context.
