RNA silencing
RNA silencing is a newly discovered mechanism of genetic regulation in eukaryotes. It is based on an immune system that protects eukaryotes against viruses and transposons and in some respects it is conceptually similar to classical humoral immunity. However RNA silencing is distinct from humoral immunity in that it only targets nucleic acids and has a specificity mechanism based on nucleic aci...
متن کاملIdentification of an RNA silencing suppressor from a plant double-stranded RNA virus.
RNA silencing is a mechanism which higher plants and animals have evolved to defend against viral infection in addition to regulation of gene expression for growth and development. As a counterdefense, many plant and some animal viruses studied to date encode RNA silencing suppressors (RSS) that interfere with various steps of the silencing pathway. In this study, we report the first identifica...
متن کاملSize Selective Recognition of siRNA by an RNA Silencing Suppressor
RNA silencing in plants likely exists as a defense mechanism against molecular parasites such as RNA viruses, retrotransposons, and transgenes. As a result, many plant viruses have adapted mechanisms to evade and suppress gene silencing. Tombusviruses express a 19 kDa protein (p19), which has been shown to suppress RNA silencing in vivo and bind silencing-generated and synthetic small interferi...
متن کاملRNA silencing in Monterey.
The tenth annual Keystone Symposium on the Mechanism and Biology of Silencing convened in Monterey, California, in March 2011. Those seeking some West Coast sunshine were, unfortunately, met with incessant precipitation throughout the meeting. Nevertheless, attendees were brightened by enlightening and vigorous scientific discussions. Here, we summarize the results presented at the meeting, whi...
متن کاملRNA-triggered gene silencing.
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. In addition to providing a surprisingly effective set of tools to interfere...
