RNA-directed DNA methylation has an important developmental function in Arabidopsis that is masked by the chromatin remodeler PICKLE
{{output}}
In Arabidopsis, RNA-directed DNA methylation (RdDM) is required for the maintenance of CHH methylation, and for de novo methylation in all (CG, CHG, and CHH) contexts, but no obvious effect of RdDM deficiency on plant development has been found to date. We sho... ...
