A Pulse–chase EdU Method for Detection of Cell Division Orientation in Arabidopsis and Juncus prismatocarpus Leaf Primordia

[Abstract]  In plants, the morphological diversity of leaves is largely determined by cell division, especially cell division orientation. Whereas cell division itself is easily monitored, the detection and quantification of cell division orientation are difficult. The few existing methods for detection and quantification of cell division orientation are either inefficient or laborious. Here, we describe a pulse-chase strategy using a 5-ethynyl-2’-deoxyuridine (EdU) labeling assay. Plant tissues are first incubated with EdU for a short period (pulse), followed by a long incubation without EdU (chase). Using this method, the positions of daughter cells are easily detected and can be used to quantify cell division orientation. Our protocol is rapid and very efficient for quantitative analysis of ... [摘要]  [摘要]在植物中,叶片的形态多样性在很大程度上取决于细胞分裂,尤其是细胞分裂方向。尽管细胞分裂本身很容易监测,但是细胞分裂方向的检测和定量却很困难。现有的几种检测和定量细胞分裂方向的方法要么效率低下要么费力。在这里,我们描述了使用5-乙炔基-2'-脱氧尿苷(EdU )标记测定的脉冲追踪策略。首先将植物组织与EdU一起短时间(脉冲)孵育,然后在没有EdU的情况下长时间孵育(追逐)。使用这种方法,子细胞的位置易于检测,可用于量化细胞分裂方向。我们的协议可以快速有效地定量分析细胞分裂方向,并且可以同时应用于模型植物和非模型植物。

[背景]植物细胞通过细胞壁彼此附接,并且不能迁移。因此,在叶片发育的早期,组织化,定向的细胞分裂在很大程度上决定了成熟叶片的形状。迄今为止,还没有报道用于有效和快速检测和定量细胞分裂取向的方法。现有方法包括使用ap CYCB1; 1 :: GUS (β-葡萄糖醛酸糖苷酶)报告基因线(末期)可视化子核(末期)(Horiguchi et al。,2011)或使用4',6-diamidino可视化纺锤状赤道(中期) -2-苯基吲哚(DAPI)染色(Fukushima et ...

Investigating Localization of Chimeric Transporter Proteins within Chloroplasts of Arabidopsis thaliana

[Abstract]  In this protocol, we describe a method to design chimeric proteins for specific targeting to the inner envelope membrane (IEM) of Arabidopsis chloroplasts and the confirmation of their localization by biochemical analysis. Specific targeting to the chloroplast IEM can be achieved by fusing the protein of interest with a transit peptide and an IEM targeting signal. This protocol makes it possible to investigate the localization of chimeric proteins in chloroplasts using a small number of transgenic plants by using a modified method of chloroplast isolation and fractionation. IEM localization of chimeric proteins can be further assessed by trypsin digestion and alkaline extraction. Here, the localization of the chimeric bicarbonate transporter, designated as SbtAII, is detected by ... [摘要]  在这个协议中,我们描述了一种设计嵌合蛋白的方法,用于特异性靶向拟南芥叶绿体的内包膜(IEM)并通过生化分析确定它们的定位。 叶绿体IEM的特异性靶向可通过将感兴趣的蛋白质与转运肽和IEM靶向信号融合来实现。 这个协议使得有可能使用少量的转基因植物,通过使用修改的叶绿体分离和分离方法来研究嵌合蛋白在叶绿体中的定位。 嵌合蛋白的IEM定位可以通过胰蛋白酶消化和碱性提取进一步评估。 在此,称为SbtAII的嵌合碳酸氢根转运蛋白的定位通过使用针对葡萄球菌蛋白A的抗体进行蛋白质印迹来检测。该方案改编自上原等人,2016年


【背景】有人提出将蓝藻CO 2浓度机制整合到叶绿体中是改善C 3+植物光合作用的有希望的方法。 根据理论估计,将BicA和SbtA整合到叶绿体IEM中可以提高光合CO 2固定率。 我们研究了核编码的蓝细菌碳酸氢盐转运蛋白BicA和SbtA与拟南芥叶绿体的IEM的整合。 因此,我们制定了一个协议,设计嵌合构造为特定目标的IEM和调查嵌合蛋白在叶绿体中的定位。

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; ...
