[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]  Filamentous fungi and bacteria form mixed-species biofilms in nature and diverse clinical contexts (Frey-Klett et al., 2011; Peleg et al., 2010). The interactions between fungi and bacteria, often mediated by secreted metabolites, have important ramifications for the biology of the interacting partners (Frey-Klett et al., 2011). This is particularly true for the bacterium Pseudomonas aeruginosa (P. aeruginosa) and the fungus Aspergillus fumigatus (A. fumigatus) which often reside in the same niche such as lungs of cystic fibrosis (CF) patients. Some studies have reported that co-infection with P. aeruginosa and A. fumigatus could lead to a decrease in lung function relative to their respective single species ... [摘要]  丝状真菌和细菌在自然界和不同的临床背景中形成混合物种生物膜(Frey-Klett等人,2011; Peleg等人,2010)。真菌和细菌之间的相互作用,通常由分泌的代谢物介导,对相互作用的伴侣的生物学具有重要的影响(Frey-Klett等人,2011)。对于绿脓假单胞菌(铜绿假单胞菌)和真菌烟曲霉( A。fumigatus >),其常常位于相同的位置,例如囊性纤维化(CF)患者的肺。一些研究报道了与p的共感染。铜绿和 烟曲霉可能导致相对于它们各自的单一物种感染的肺功能降低(Amin等人,2010; Peleg等人,2010)。代谢物提取和分析允许表征多微生物生物膜中的特定微生物代谢物。该方案描述了如何在固体培养基上制备假单胞菌属 - 曲霉菌共培养生物膜以准备代谢物提取。
