[Abstract]  Organisms have developed many protective systems to reduce the toxicity from heavy metals. The nematode Caenorhabditis elegans has been widely used to determine the protective mechanisms against heavy metals. Responses against heavy metals can be monitored by expression of reporter genes, while sensitivity can be determined by quantifying growth or survival rate following exposure to heavy metals. [摘要]  生物开发了许多保护系统,以减少重金属的毒性。线虫秀丽隐杆线虫已广泛用于确定重金属的保护机制。可以通过报告基因的表达来监测对重金属的反应,而敏感性可以通过量化暴露于重金属后的生长或存活率来确定。

背景 一些重金属如砷,镉和汞已知对包括人类在内的大多数生物有害(Valko et al。,2005)。为了降低这些金属的毒性,生物开发出各种保护系统。线虫秀丽隐杆线虫已被用于了解重金属的保护机制。以前的研究表明,许多基因,如解毒酶,转录因子和信号传导因子都参与了该生物体中重金属的保护(Broeks et al。,1996; Mizuno et al。 ,2004; Inoue等人,2005; Schwartz等人,2010)。除了测量报告基因表达外,生存力和生长的测定通常用于监测重金属在C中的影响。线虫。在本协议中,我们描述了使用C测定砷,铜和镉的方法。线虫。

[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; ...

[Abstract]  Cyanobacteria are prokaryotic organisms that perform oxygenic photosynthesis. Freshwater cyanobacteria, such as Synechococcus elongatus PCC 7942 and Synechocystis sp. PCC 6803, are model organisms for the study of photosynthesis, gene regulation, and biotechnological applications because they are easy to manipulate genetically. However, while studying these cyanobacteria, care has to be taken with respect to genetic heterogeneity in the establishment of gene disruptants, because these cyanobacteria contain multiple chromosomal copies per cell. Here, we describe a method for the estimation of chromosomal copy number in Synechococcus 7942. Using this method, we have recently observed that the chromosomal copy number of Synechococcus 7942 ... [摘要]  蓝细菌是进行含氧光合作用的原核生物。 淡水蓝细菌,例如细长聚球藻PCC 7942和聚集细胞 PCC 6803是用于研究光合作用,基因调节和生物技术应用的模式生物,因为它们易于基因操作。 然而,当研究这些蓝细菌时,必须注意遗传异质性在基因破坏物的建立中,因为这些蓝细菌每个细胞含有多个染色体拷贝。 在这里,我们描述了用于估计在聚球藻7942中的染色体拷贝数的方法。使用这种方法,我们最近观察到,聚球藻7942的染色体拷贝数显着地改变 其生长阶段。 这种技术可用于研究多倍体不仅在蓝细菌,而且在其他多倍体生物。
