Tomato and Tobacco Phytoene Desaturase Gene Silencing by Virus-Induced Gene Silencing (VIGS) Technique
Background and Aims: Virus-Induced Gene Silencing (VIGS) is a virus vector technology that exploits antiviral defense mechanism. By infecting plants with recombinant viruses containing host genes inserted in the viral genome, VIGS achieves the RNA silencing process. The purpose of this study was to investigate the possibility of tomato (Lycopersicon esculentum Mill.) and tobacco (Nicotiana be...
متن کاملVirus-induced gene silencing in plants.
Virus-induced gene silencing (VIGS) is a technology that exploits an RNA-mediated antiviral defense mechanism. In plants infected with unmodified viruses the mechanism is specifically targeted against the viral genome. However, with virus vectors carrying inserts derived from host genes the process can be additionally targeted against the corresponding mRNAs. VIGS has been used widely in plants...
متن کاملSugarcane Mosaic Virus-Based Gene Silencing in Nicotiana benthamiana
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 modified by inserting a gene segment of SCMV in place of Tobacco rattle virus (TRV) genome part 1 (TRV1 or RNA1)...
متن کاملFoxtail Mosaic Virus-Induced Gene Silencing in Monocot Plants.
Virus-induced gene silencing (VIGS) is a powerful technique to study gene function in plants. However, very few VIGS vectors are available for monocot plants. Here we report that Foxtail mosaic virus (FoMV) can be engineered as an effective VIGS system to induce efficient silencing of endogenous genes in monocot plants including barley (Hordeum vulgare L.), wheat (Triticum aestivum) and foxtail...
متن کاملResistance Gene to MAIDS Virus-Infected Mice
To examine whether the resistance allele of the Fv-4 gene (the Fv-4r gene) is a dominant inhibitory-productencoding gene which can be used to prevent the development of murine AIDS (MAIDS), bone marrow cells from BALBIc-Fv-4wr mice were transplanted into BALB/c mice and C57BL/6 mice infected with MAIDS virus. Mimost all of the virus-infected BALB/c and C57BL/6 mice developed MAIDS within 4 mont...
