Summary: Latest advances in the use of double-stranded RNA as tool for viral protection in tomato plants. Lately, great attention has been diverted to elucidating the mechanisms underlining plant gene silencing and the action of non-coding RNA in plants. Concomitantly, knowledge about the interactions between plants and pathogens has evolved greatly, bringing to the spotlight the importance of double-stranded RNA (dsRNA) as a tool to generate or improve resistance against plant pathogens. Plant viruses are responsible for important losses in the yield of several commodities. Viruses are very diverse, and to date, no products available in the market allow effective control of viral infections. The use of dsRNA molecules as a tool is based on the plant gene-silencing pathways (GS). After being topically applied, the dsRNA can activate GS, which uses it as a template for synthesizing small RNAs, leading to the degradation of specific RNA molecules present in the plant cell.
