“…For example, the genus Tospovirus is one of the key viral pathogens of plants found to be economically important by threatening vegetable production in India. Groundnut bud necrosis virus, a species of Tospovirus causes nearly 80 per cent crop loss in tomato and other Solanaceous crops under field conditions (Kunkalikar et al, 2010(Kunkalikar et al, , 2011Sushmitha and Bhat, 2014). Similarly, strains of Cassava mosaic virus cause more than 25 million tons of losses every year in Africa, India and Sri Lanka (Legg and Thresh, 2000).…”

RNAs play a significant role in regulating gene expression and their principal areas have been exploited for the control of plant viruses by the discovery of RNA silencing mechanism. RNA silencing or RNA interference (RNAi) is an innovative mechanism that regulates and restricts the amount of transcripts either by suppressing transcription (TGS) or by the degradation of sequence-specific RNA. RNAi can be used effectively to study the role of genes in a variety of eukaryotic organisms by reverse genetics. The technology has been employed in several fields such as drug resistance, therapeutics, development of genetically modified animals for research and transgenic plants targeting plant viruses. In plants, small interfering RNAs (siRNA) are the characteristic of 21 to 22 bp long dsRNA, which has been recognized by the regulatory mechanism of RNAi and leads to the sequence-specific degradation of target mRNA. In addition to virus disease control, RNAi can also be used to control mycotoxins and plant diseases caused by other organisms. This review enhances our current knowledge of RNAi and its larger applications in agriculture, specifically in plant virus disease management.
