Gene silencing has evolved in a broad range of organisms probably as defense mechanisms against invasive nucleic acids. Two major strategies are utilized. Transcriptional gene silencing (TGS) acts to prevent RNA synthesis and posttranscriptional gene silencing (PTGS) acts to degrade existing RNA.

In diverse organisms, small RNAs derived from cleavage of double-stranded RNA can trigger epigenetic gene silencing in the cytoplasm and at the genome level. Small RNAs can guide posttranscriptional degradation of complementary messenger RNAs and, in plants, transcriptional gene silencing by methylation of homologous DNA sequences.

Transcriptional gene silencing mutants
Plant Molecular Biology, 2000Genetic approaches to identify molecular components of transcriptional gene silencing (TGS) in plants have yielded several Arabidopsis thaliana mutants and identified the first genes involved. All mutations found affect the maintenance of silencing and reactivate silent genes in trans.

A number of gene-silencing phenomena including co-suppression discovered in plants, quelling in fungi and RNA interference in animals have been revealed to have steps in common. All occur in the cytoplasm at a post-transcriptional level with the mRNAs of target genes degraded in a sequence-specific manner. Small non-coding RNA molecules demonstrated to

In the postgenomic era, large-scale functional genomic approaches are necessary for converting sequence information into functional information. A para-genetic approach, called virus-induced gene silencing (VIGS), offers a rapid means of gaining insight into gene function in plants.

Gene Regulation Histone proteins wrap around DNA to form nucleosomes that package metazoan DNA into the nucleus. Chromatin compaction is also believed to be critical for the repression of homeotic genes by the Polycomb repressive complex 1 (PRC1) during development. Lau et al.

Double-stranded RNA (dsRNA) has recently been shown to trigger sequence-specific gene silencing in a wide variety of organisms, including nematodes, plants, trypanosomes, fruit flies and planaria; meanwhile an as yet uncharacterized RNA trigger has been shown to induce DNA methylation in several different plant systems.
