Virus-based MicroRNA Silencing

[Abstract]  Virus-based microRNA silencing (VbMS) is a viable and prompt method to screen and characterize the function of microRNAs (miRNAs) in plants. The Tobacco rattle virus (TRV)-based VbMS method was originally developed by the Yule Liu's group (Sha et al., 2014) using miRNA target mimic (TM) methodology. Here, we describe the TRV-based VbMS method for silencing endogenous miRNA in Nicotiana benthamiana and tomato via Agrobacterium infiltrations. For each assay, Agrobacterium cultures containing pTRV1 and specific pTRV2e derivative harboring TM fragments ... [摘要]  基于病毒的微RNA沉默(VbMS)是筛选和表征微RNA(miRNA)在植物中的功能的可行和迅速的方法。 基于烟草响铃病毒(TRV)的VbMS方法最初是由Yule Liu的小组(Sha等人,2014)使用miRNA靶模拟物TM方法开发的。 在这里,我们描述基于TRV的VbMS方法,用于通过土壤杆菌浸润物在本氏烟草和番茄中沉默内源性miRNA。 对于每个测定,将含有pTRV1的土壤杆菌培养物和含有TM片段的特异性pTRV2e衍生物混合并渗入植物组织中。 通常在3周内,靶miRNA基因将被沉默,并且新开发的组织将显示相应的表型。

[Abstract]  Virus-induced gene silencing (VIGS) is a powerful method to study gene function in plants. Tobacco rattle virus (TRV)-based VIGS vector is the most efficient VIGS vector so far. This method was originally developed by the Dinesh-Kumar's group (Liu et al., 2002) . Here, we describe a rapid and high efficient TRV-based VIGS method for knocking down genes in Nicotiana benthamiana. For TRV-based VIGS, Agrobacterium culture containing pTRV1 and Agrobacterium culture containing pTRV2 with plant target gene fragment are mixed and infiltrated into the lower leaves ... [摘要]  病毒诱导基因沉默(VIGS)是研究植物中基因功能的有力方法。 迄今为止,基于烟草瘟病毒(TRV)的VIGS载体是最有效的VIGS载体。 该方法最初由Dinesh-Kumar的小组开发(Liu等人,2002)。 在这里,我们描述了一种快速和高效的基于TRV的VIGS方法,用于在本氏烟草中敲除基因。 对于基于TRV的VIGS,将含有具有植物靶基因片段的pTRV2的pTRV1和农杆菌培养物的农杆菌培养物混合并渗入植物的下叶。 在浸润后2-3周后,植物靶基因将被沉默。
