Abstract: Background RNA-directed DNA methylation (RdDM) initiates cytosine methylation in all contexts and maintains asymmetric CHH methylation. Mature plant embryos show one of the highest levels of CHH methylation, and it has been suggested that RdDM… read more here.

Abstract: RNA-mediated transcriptional silencing, in plants known as RNA-directed DNA methylation (RdDM), is a conserved process where small interfering RNA (siRNA) and long non-coding RNA (lncRNA) help establish repressive chromatin modifications. This process represses transposons and… read more here.

Abstract: RNA-directed DNA methylation (RdDM) is a plant-specific de novo DNA methylation mechanism that requires long noncoding RNA (lncRNA) as scaffold to define target genomic loci. While the role of RdDM in maintaining genome stability is… read more here.
