Sugarcane 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 کاملTomato 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 کاملTransient expression of coding and non-coding regions of PVY confer resistance to virus infection
One of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific RNA-dependent silencing pathway termed post-transcriptional gene silencing(PTGS). In this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. Potato VirusY (PVY) is one of the mostdamaging viruses of potato, infecting...
متن کاملUtility of P19 Gene-Silencing Suppressor for High Level Expression of Recombinant Human Therapeutic Proteins in Plant Cells
Background: The potential of plants, as a safe and eukaryotic system, is considered in the production of recombinant therapeutic human protein today; but the expression level of heterologous proteins is limited by the post-transcriptional gene silencing (PTGS) response in this new technology. The use of viral suppressors of gene silencing can prevent PTGS and improve transient expression level ...
متن کاملتاثیر دویدن اجباری هوازی کوتاه مدت بر بیان ژن‌های miR-124 وRE1-Silencing Transcription Factor در هیپوکامپ موش‌های صحرایی نر بالغ
Background and Objective: Transcription factors (TF) and microRNAs, are the largest families of transacting gene regulatory molecules in multicellular organisms. Our goal was to examine the effect of aerobic running on the expression of miR-124 and RE1-silencing TF in the hippocampus of adult male Wistar rats. Materials and Methods: A total of twelve 8-week-old adult male Wistar rats with a mea...
متن کاملThe Effect of Chalcone Isomerase (Chi) Gene Silencing on Flavonoids Content in Petunia hybrida using RNAi Technology
have been bred with altered flower color using genetic engineering approaches. One of the most effective applications is the reduction of flower pigments by suppression of involved enzymes in their biosynthesis pathways. RNA interference (RNAi) has provided an effective tool for the knock down of genes involved in the production of flower pigments. In this study, a chi-RNAi construct was design...
