There are three different types of DNA methylation in plants: CG, CHH (where H is any base except G), and CHG. In Arabidopsis, CG methylation is found on some genes, but primarily on repeat sequences that make up transposons, as well as other repeat sequences in the genome. CHH methylation is found only where there is CG methylation and often near transposable elements, though some evidence points to CHH methylation on some silenced genes as well. CHG methylation is typically found with the CHH variety.

Every time a cell divides, it must replicate its genome and its epigenome. Plants have diverse pathways overseeing the faithful passage of the methylome to daughter cells.
CG methylation Copying CG methylation patterns to the two daughter strands is relatively ...
