Technical date May 2010 RNA directed DNAmethylation RdDM is an epigenetics epigenetic process first elucidated in plants whereby small double stranded RNA s dsRNA s are processed to guide methylation to complementary DNA locus genetics loci . In the model plant organism Arabidopsis thaliana , these small dsRNA s may be generated from three sources Viral replication intermediates Products of the endogenous RNA dependent RNA polymerase Transcribed inverted repeats These dsRNAs are then processed to direct histone 3 lysine 9 H3K9 methylation via Ago4 and the SUVH Suppressor of Variegation Homolog histone methyltransferase family. This H3K9 dimethylation is then putatively bound by the cytosine methyltransferase CMT3, which methylates cytosines in a non CG context. These marks, H3K9 dimethylation and cytosine methylation, are canonical marks of gene silencing . Thus small double stranded RNAs generated in diverse contexts bring about transcriptional silencing at specific loci.

Histone methylation is the modification of certain amino acids in a histone protein by the addition of one, two, or three methyl groups. In the cell nucleus, DNA is wound around histones. Methylation and demethylation of histones turns the genes in DNA off and on , respectively, either by loosening their tails, thereby allowing transcription factors and other proteins to access the DNA, or by encompassing their tails around the DNA, thereby restricting access to the DNA. This is true in most cases. Function This modification alters the properties of the nucleosome and affects its interactions with other proteins. Histone methylation is in general associated with transcriptional Repressor repression . However, methylation of some lysine and arginine residues of histones results in transcriptional activation. Examples include methylation of lysine 4 of histone 3 H3K4 , and arginine R residues on H3 and Histone H4 H4 .
