Diverse small RNA-directed silencing pathways in plants.
Small silencing RNAs of 21- to 24-nucleotide (nt) in length are essential regulatory components expressed in most eukaryotic organisms. These regulatory small RNAs are produced through pathways that involve several evolutionarily conserved protein families, including DICER (DCR) or DICER-LIKE (DCL), ARGONAUTE (AGO), and RNA-DEPENDENT RNA POLYMERASE (RDR). Plants possess multiple functional DCL,...
متن کاملThe diversity of RNA silencing pathways in plants.
RNA silencing was discovered in plants as a mechanism whereby invading nucleic acids, such as transgenes and viruses, are silenced through the action of small (20-26 nt) homologous RNA molecules. Our understanding of small RNA biology has significantly improved in recent years, and it is now clear that there are several cellular silencing pathways in addition to those involved in defense. Endog...
متن کاملRNA silencing movement in plants.
Multicellular organisms, like higher plants, need to coordinate their growth and development and to cope with environmental cues. To achieve this, various signal molecules are transported between neighboring cells and distant organs to control the fate of the recipient cells and organs. RNA silencing produces cell non-autonomous signal molecules that can move over short or long distances leadin...
متن کاملDistinct Effects of p19 RNA Silencing Suppressor on Small RNA Mediated Pathways in Plants
RNA silencing is one of the main defense mechanisms employed by plants to fight viruses. In change, viruses have evolved silencing suppressor proteins to neutralize antiviral silencing. Since the endogenous and antiviral functions of RNA silencing pathway rely on common components, it was suggested that viral suppressors interfere with endogenous silencing pathway contributing to viral symptom ...
متن کاملSmall RNA Pathways in Plants
When James Watson and Francis Crick reported the structure of DNA in 1953, the mechanism of inheritance was instantly apparent. The complementary pairing of the DNA bases in the double helix, the pair famously wrote, “immediately suggests a possible copying mechanism for the genetic material.’’ The structure helped explain one of the central problems of modern biology: how does genetic material...
