Abstract excerpt
In mammals, some fungi, and plants, DNA methylation plays a central role in the epigenetic control of gene transcription. Recently, however, a subclass of Arabidopsis mutants revealed that the release of transcriptional gene silencing (TGS) does not necessarily require DNA demethylation. Here, we address the fundamental question of whether these mutants delineate a previously uncharacterized,...
