[Abstract]  RNA-guided endonucleases (RGENs) have been used for genome editing in various organisms. Here, we demonstrate a simple method for performing targeted mutagenesis and genotyping in a model moss species, Physcomitrella patens, using RGENs. We also performed targeted mutagenesis in a non-model moss, Scopelophilla cataractae, using a similar method (Nomura et al., 2016), indicating that this experimental system could be applied to a wide range of mosses species. [摘要]  RNA引导的核酸内切酶(RGENs)已被用于各种生物体的基因组编辑。 在这里,我们展示了使用RGENs在模型苔藓种类小立碗藓中进行定向诱变和基因分型的简单方法。 我们还使用类似的方法(Nomura等,2016)在非模型苔藓,Scopelophilla白内障中进行了定向诱变,表明该实验系统可以应用于广泛的苔藓物种。
【背景】使用来自适应性免疫系统的RNA引导内切核酸酶(RGEN)的靶向诱变,使用细菌CRISPR(定期间隔的回文重复序列)/ Cas(CRISPR相关)系统近年来已经急剧发展。在该方法中,使用源自化脓性链球菌的Cas9核酸内切酶和人工设计的单链导向RNA(sgRNA)。 Cas9-sgRNA复合物识别原始相邻基序(5'-NGG-3'),并在目标位点上游3 bp切割(Jinek等,2012)。随后,在DNA的双链断裂(DSB)修复过程中发生随机插入和/或缺失突变。使用这些RGEN的定向诱变是有效的以及成本和时间有效的,它已被用于各种生物体(包括许多植物物种)的基因组编辑。在这里,我们在青苔中建立了使用RGEN进行靶向诱变的方案,并在模型和非模型物种中进行了证明(Nomura等,2016)。

CRISPR-PCS Protocol for Chromosome Splitting and Splitting Event Detection in Saccharomyces cerevisiae

[Abstract]  Chromosome engineering is an important technology with applications in basic biology and biotechnology. Chromosome splitting technology called PCS (PCR-mediated Chromosome Splitting) has already been developed as a fundamental chromosome engineering technology in the budding yeast. However, the splitting efficiency of PCS technology is not high enough to achieve multiple splitting at a time. This protocol describes a procedure for achieving simultaneous and multiple chromosome splits in the budding yeast Saccharomyces cerevisiae by a new technology called CRISPR-PCS. At least four independent sites in the genome can be split by one transformation. Total time and labor for obtaining a multiple split yeast strain is drastically reduced when compared with conventional PCS ... [摘要]  染色体工程是应用于基础生物学和生物技术的重要技术。染色体分裂技术称为PCS(PCR介导的染色体分裂)已经被开发为发芽酵母中的基本染色体工程技术。然而,PCS技术的分割效率不够高,不能一次实现多次分割。该协议描述了通过称为CRISPR-PCS的新技术在芽状酵母酿酒酵母中实现同时和多个染色体分裂的过程。基因组中至少四个独立的位点可以通过一次转化来分裂。与常规PCS技术相比,获得多重分裂酵母菌株的总时间和劳动力大大降低。

背景 能够快速有效地操纵多个遗传基因座或染色体区域的染色体工程技术变得越来越重要。这些技术为阐明染色体和基因组功能提供了有力的手段。此外,它可以用于通过创建广泛的遗传变体来繁殖有用的菌株。在芽殖酵母酿酒酵母(Saccharomyces ...
