[Abstract]  Besides analyzing the composition and dynamics of microbial communities, plant microbiome research aims to understanding the mechanism of plant microbiota assembly and their biological functions. Here, we describe procedures to investigate the role of bacterial interspecies interactions in root microbiome assembly and the beneficial effects of the root microbiota on hosts by using a maize root-associated simplified seven-species (Stenotrophomonas maltophilia, Ochrobactrum pituitosum, Curtobacterium pusillum, Enterobacter cloacae, Chryseobacterium ... [摘要]  除了分析微生物群落的组成和动态外,植物微生物群落研究的目的在于了解植物微生物群落组装的机制及其生物学功能。在这里,我们描述了通过使用与玉米根相关的简化的七种物种(嗜麦芽窄食单胞菌(Stenotrophomonas maltophilia),)来研究细菌种间相互作用在根微生物群组装中的作用以及根菌群对宿主的有益影响的程序。 Ochrobactrum pituitosum ,Curtobacterium pusillum ,阴沟肠杆菌, Chryseobacterium indologenes ,<在我们以前的工作中描述过的假单胞菌(pseudomonas putida))合成细菌群落。表面灭菌的玉米种子在含有多种细菌的悬浮液中浸泡后,在基于双管生长室的非生物体系中生长。通过对7种菌株中的每种菌株选择性培养基的培养依赖性方法追踪定殖在玉米根部的细菌群组成的动态。通过监测社区结构的变化来评估细菌相互作用对社区组装的影响。通过量化(1)真菌植物病原体,种子表面上的fusarium="" verticillioides和(2)幼苗枯萎的严重程度来评估简化的7种群落的植物保护效果真菌引起的疾病,在细菌群落的存在和不存在的情况下。我们的方案将作为研究实验室条件下植物="" -=""> ...

DNA-free Genome Editing of Chlamydomonas reinhardtii Using CRISPR and Subsequent Mutant Analysis

[Abstract]  We successfully introduced targeted knock-out of gene of interest in Chlamydomonas reinhardtii by using DNA-free CRISPR. In this protocol, the detailed procedures of an entire workflow cover from the initial target selection of CRISPR to the mutant analysis using next generation sequencing (NGS) technology. Furthermore, we introduce a web-based set of tools, named CRISPR RGEN tools (http://www.rgenome.net/), which provides all required tools from CRISPR target design to NGS data analysis. [摘要]  我们通过使用无DNA的CRISPR成功地引入了目标克隆在赖氨酸衣藻中的目标基因敲除。在该协议中,整个工作流程的详细过程涵盖从初始目标选择CRISPR到使用下一代测序(NGS)技术的突变体分析。此外,我们介绍一种基于Web的工具集,名为CRISPR RGEN工具( http:// www.rgenome.net/ ),其中提供了CRISPR目标设计到NGS数据分析的所有必需工具。

背景 我们最近报道(Baek等人,2016),使用预先组装的Cas9蛋白质指导RNA核糖核蛋白,模型绿色微藻(Chlamydomonas ...
