WebMay 22, 2014 · De novo DNA methylation in all sequence contexts is mediated by DRM2 and is dependent on RNAi-like machinery via a process termed RNA-directed DNA methylation (RdDM) (Law and Jacobsen, 2010). This pathway involves two main phases: an upstream small interfering RNA (siRNA) biogenesis phase and a downstream … WebOct 8, 2024 · RNA-directed DNA methylation (RdDM) is a biological process in which non-coding RNA molecules direct the addition of DNA methylation to specific DNA sequences. The RdDM pathway is unique to plants, although other mechanisms of RNA-directed chromatin modification have also been described in fungi and animals. To date, the …
WebDe novo DNA methylation and the maintenance of DNA methylation in asymmetrical sequence contexts is catalyzed by homologous proteins in plants (DRM2) and animals (DNMT3a/b). In plants, targeting of DRM2 depends on small interfering RNAs (siRNAs), although the molecular details are still unclear. Here, we show that two SRA-domain …
