Sugarcane Mosaic Virus-Based Gene Silencing in Nicotiana benthamiana.

ABSTRACT: Background: Potyvirus-based virus-induced gene silencing (VIGS) is used for knocking down the expression of a target gene in numerous plant species. Sugarcane mosaic virus (SCMV) is a monopartite, positive single strand RNA virus. Objectives: pBINTRA6 vector was modifi ed by inserting a gene segment of SCMV in place of Tobacco rattle virus (TRV) genome part 1 (TRV1 or RNA1) and the two nonstructural proteins of TRV2(RNA2). Materials and Methods: SCMV construct was inoculated into 3-4 weeks Nicotiana benthamiana plant leaves either by using a needleless syringe or applying pricking with a toothpick. Results: The construct (SCMV-RNA2) successfully induced post-transcriptional gene silencing (PTGS) of the target genes GFP and ChlI
