Haustorium Induction Assay of the Parasitic Plant Phtheirospermum japonicum

[Abstract]  Phtheirospermum japonicum is a facultative root parasitic plant in the Orobanchaceae family used as a model parasitic plant. Facultative root parasites form an invasive organ called haustorium on the lateral parts of their roots. To functionally characterize parasitic abilities, quantification of haustorium numbers is required. However, this task is quite laborious and time consuming. Here we describe an efficient protocol to induce haustorium in vitro by haustorium-inducing chemicals and host root exudate treatments in P. japonicum. [摘要]  Phtheirospermum japonicum 是用作模型寄生植物的Orobanchaceae科的兼性根寄生植物。兼性根寄生虫在其根部的侧面部分形成称为吸管的侵入性器官。为了在功能上表征寄生能力,需要量化痰液数量。然而,这项任务是非常费力和耗时的。在这里,我们描述了一种有效的方案,通过引诱化学药物和宿主根系渗出物处理在体外诱导体外释放。血吸虫。

背景 寄生植物已经演变成从其他植物获得营养。一些寄生植物通过感染商业作物对农业造成重大损害(Spallek等人,2013)。有义务的寄生植物需要宿主完成其生命周期,而兼性寄生植物可以在没有宿主作为自养生物体的情况下存活,但如果宿主植物在附近则通过感染转移到异养(Westwood等人,2010)。所有寄生植物的共同特征是称为ium a的专门器官,其通过建立血管桥连接寄生虫与宿主(Saucet和Shirasu,2016; ...

Rapid Isolation of Total Protein from Arabidopsis Pollen

[Abstract]  Arabidopsis pollen is an excellent system for answering important biological questions about the establishment and maintenance of cellular polarity and polar cell growth, because these processes are amenable to the genetic and genomic approaches that are readily available in Arabidopsis. Given that proteins are the direct executors of a wide variety of cellular processes, it is important to rapidly and efficiently isolate total protein for various protein-based analyses, such as Western blotting, co-immunoprecipitation and mass spectrometry, among others. Here we present a ... [摘要]  拟南芥花粉是用于回答关于细胞极性和极性细胞生长的建立和维持的重要生物学问题的优秀系统,因为这些方法适用于在中容易获得的遗传和基因组方法, 拟南芥。 鉴于蛋白质是各种细胞过程的直接执行者,重要的是快速有效地分离各种基于蛋白质的分析的总蛋白质,例如Western印迹,共免疫沉淀和质谱等。 在这里,我们提出了一种从拟南芥花粉中快速分离总蛋白的方案,该方法是从我们最近发表的论文(Chang and Huang,2015)中得到改编的。
花粉是性繁殖植物生命周期的关键阶段。花粉萌发和随后的管生长提供了两个非活动精子细胞在开花植物中进行双重受精的通道。花粉通常被用作解决基本细胞生物学问题的示范系统,例如细胞极性和极细胞生长的建立和维持,以及肌动蛋白细胞骨架的结构和功能(Chen等人, ,2009; Qu等人,2015)。通常来自百合和烟草的花粉由于粒度大而被广泛使用,这使得它们在显微镜下容易收集和观察。相比之下,拟南芥花粉小,收集大量花粉以分离足够量的蛋白质以进行下游分析(如Western印迹和质谱法)相对困难。因此,开发快速分离总拟蛋白质拟南芥花粉的方案将有助于相关分析。

Lentiviral Barcode Labeling and Transplantation of Fetal Liver Hematopoietic Stem and Progenitor Cells

[Abstract]  Cellular barcoding enables the dissection of clonal dynamics in heterogeneous cell populations through single cell lineage tracing. The labeling of hematopoietic stem and progenitor cells (HSPCs) with unique and heritable DNA barcodes, makes it possible to resolve donor cell heterogeneity in terms of differentiation potential and lineage bias at the single cell level, through subsequent transplantation and high-throughput sequencing. Furthermore, cellular barcoding allows for bona fide hematopoietic stem cells (HSCs) to be defined based on functional rather than immunophenotypic parameters. ... [摘要]  细胞条形码可以通过单细胞谱系追踪来分离异种细胞群体中的克隆动力学。通过独特和可遗传的DNA条形码对造血干细胞和祖细胞(HSPC)进行标记,可以通过随后的移植和高通量测序,在单细胞水平上分化供体细胞异质性,分化潜力和谱系偏倚。此外,细胞条形码可以根据功能而不是免疫表型参数定义真正的造血干细胞(HSC)。
 该协议描述了慢病毒细胞条形码的工作流程,追踪1450天后(dpc)胎肝(FL)Lineage-Sca+ cKit + (LSK)HSPC经过长期重建(图1)(Kristiansen等人,2016),但可以适应于选择的细胞类型或时间框架。
