Zaratiegui M, & Martienssen R (2012). The persistence of a silent memory. Nat Genet, 44, 118-9. doi:10.1038/ng.1088
One of the most striking properties of RNA interference (RNAi) in Caenorhabditis elegans is its persistence in offspring after the triggering double-stranded RNA (dsRNA) has disappeared. A new study reveals that a heterochromatic silencing mark is deposited around the targets of RNAi and is transmitted through generations. These results show that RNAi can induce stable and heritable chromatin modifications in animals.
