Microscopic Observation of Subcellular GFP-tagged Protein Localization in Rice Anthers

[Abstract]  This protocol demonstrates a simple method to determine the subcellular localization of fluorescence-tagged proteins on the vibratome sections of rice developing anthers. If a cell type-specific promoter is used to drive the tagged protein-encoding gene, the method enables to clearly distinguish the cells retaining fluorescent signals from other anther cells. It is applicable to both live and fixed samples, and presumably to other plant tissues. [摘要]  该方案演示了一种确定荧光标记蛋白在水稻发育花药的振动切片上的亚细胞定位的简单方法。 如果使用细胞类型特异性启动子来驱动标记的蛋白质编码基因,该方法能够清楚地区分保留荧光信号的细胞与其他花药细胞。 它适用于活的和固定的样品,并且可能适用于其他植物组织。

Efficient AAV-mediated Gene Targeting Using 2A-based Promoter-trap System

[Abstract]  Adeno-associated virus (AAV)-based targeting vectors have 1-4-log higher gene targeting efficiencies compared with plasmid-based targeting vectors. The efficiency of AAV-mediated gene targeting is further increased by introducing a promoter-trap system into targeting vectors. In addition, we found that the use of ribosome-skipping 2A peptide rather than commonly used internal ribosome entry site (IRES) in the promoter-trap system results in significantly higher AAV-mediated gene targeting efficiencies (Karnan et al., 2016). In this protocol, we describe the procedures for ... [摘要]  与基于质粒的靶向载体相比,基于腺相关病毒(AAV)的靶向载体具有1-4对较高的基因靶向效率。 通过将启动子捕获系统引入靶向载体中,AAV介导的基因靶向的效率进一步增加。 此外,我们发现使用核糖体跳跃2A肽而不是通常使用的内部核糖体进入位点(IRES)在启动子捕获系统中导致显着更高的AAV介导的基因靶向效率(Karnan等,2016)。 在该方案中,我们描述了AAV介导的基因靶向开发2A用于启动子捕获的程序,包括基于平台质粒pAAV-2Aneo或pAAV-2Aneo v2的靶向载体的构建,AAV颗粒的产生,细胞感染 基于AAV的靶向载体,以及基因靶向细胞克隆的分离和验证。
【背景】以前在其他方案中描述了AAV介导的基因靶向的程序(对应于本方案的BG部分)(Kohli等人,2004; Rago等人,2007; Khan等人,2011; Howes and Schofield ,2015)。 然而,该方案提供了如何使用基于2A的启动子捕获系统首次进行AAV介导的基因靶向的详细描述。
