From: Levels of DNA methylation and transcript accumulation in leaves of transgenic maize varieties
Cytosine methylation levels of single and stacked maize varieties in four regions of the transgenes. The levels of cytosine methylation were measured in CG, CHG and CHH residues. a FMV promoter region; b cry2Ab2 transgene region; c 35S promoter region; d cry1A.105 transgene region. Vertical bars indicate standard errors. Means followed by different letters in the same cytosine type are significantly different according to the Wilcoxon-Mann–Whitney test (p < 0.05). Exact p values for the statistical test of each of the cytosine comparisons are shown on the right upper corner
