[Abstract]  The establishment of the CRISPR/Cas9 technology in diatoms (Hopes et al., 2016; Nymark et al., 2016) enables a simple, inexpensive and effective way of introducing targeted alterations in the genomic DNA of this highly important group of eukaryotic phytoplankton. Diatoms are of interest as model microorganisms in a variety of areas ranging from oceanography to materials science, in nano- and environmental biotechnology, and are presently being investigated as a source of renewable carbon-neutral fuel and chemicals. Here we present a detailed protocol of how to perform CRISPR/Cas9 gene editing of the marine diatom Phaeodactylum tricornutum, including: 1) insertion of guide RNA target site in the diatom optimized CRISPR/Cas9 vector (pKS diaCas9-sgRNA), 2) ... [摘要]  在硅藻(Hopes ,2016; Nymark等人,2016)中建立了CRISPR / Cas9技术,使得能够简单,廉价和有效地引入目标 这个非常重要的真核浮游植物群的基因组DNA的改变。 硅藻在纳米和环境生物技术领域从海洋学到材料科学,各种领域的示范性微生物都是有意义的,目前正在作为可再生碳中和燃料和化学品的来源进行调查。 在这里,我们提出了如何进行海洋硅藻三角褐指藻CRISPR / Cas9基因编辑的详细方案,包括:1)在硅藻优化的CRISPR / Cas9载体(pKS diaCas9)中插入引导RNA靶位点 -sgRNA),2)用于将pKS diaCas9-sgRNA质粒导入P的生物弹道转化。 三分支毛细胞和3)基于高分辨率熔融的PCR测定以筛选CRISPR / Cas9诱导的突变。
【背景】CRISPR / Cas9系统已被证明是许多真核生物中非常有效和成功的基因组编辑系统,现在也包括微藻(Hopes等人,2016; Nymark等人)。 ,2016; Shin 等人,2016)。 CRISPR / Cas9系统包括引导RNA(gRNA)和称为Cas9的核酸酶(Sander and Joung,2014)。 这两个分子形成复合物,其中gRNA将复合物引导至感兴趣的靶标。 ...

Whole-seed Immunolabeling of Arabidopsis Mucilage Polysaccharides

[Abstract]  In addition to synthesizing and secreting copious amounts of pectic polymers (Young et al., 2008), Arabidopsis thaliana seed coat epidermal cells produce small amounts of cellulose and hemicelluloses typical of secondary cell walls (Voiniciuc et al., 2015c). These components are intricately linked and are released as a large mucilage capsule upon hydration of mature seeds. Alterations in the structure of minor mucilage components can have dramatic effects on the architecture of this gelatinous cell wall. The immunolabeling protocol described here makes it possible to visualize the distribution of specific polysaccharides in the seed mucilage capsule. [摘要]  除了合成和分泌大量的果胶聚合物(Young等人,2008)外,拟南芥种皮表皮细胞产生少量的二级纤维素和半纤维素细胞壁(Voiniciuc等,,2015c)。这些组分复杂连接,并在成熟种子水合时作为大胶囊释放。在较小的粘液组分的结构中的改变可以对该凝胶状细胞壁的结构产生显着的影响。这里描述的免疫标记方案使得可以可视化种子胶囊中特定多糖的分布。

背景 自从拟南芥种皮表皮细胞(Young等人,2008)第一次富含果胶的胶质综合免疫荧光分析以来,在这种特殊的细胞壁中已经检测到另外类型的多糖(Voinicucucum,等等。,2015a; 2015b和2015c)。为了平行处理更多的样本,我修改了原始方案(在1.5 ml微量离心管中执行; Young等人,2008; Harpaz-Saad等人,2011年)到24孔板格式。我建议用Pontamine S4B(一种比以前的污渍更具体的纤维素荧光染料)来重新研磨种子(Anderson等人,2010)。通过测试多个荧光团之间的串扰,并为图像采集和处理设定明确的指导,该方案产生可重复的粘液表型,可以可靠地解释。
