Fig. 5. Cytosine methylation profile of the PHE13000::GUS_3' transgene in wild-type and drm1/drm2-mutant background compared with the methylation profile of the endogenous PHE1 locus analyzed by bisulfite sequencing. Cytosine positions relative to the translational stop codon and sequence contexts (CG and CNG, CNN not indicated) are indicated on the x-axis.
