[Abstract]  Biofilms are sessile communities of microbial cells embedded in a self-produced or host-derived exopolymeric matrix. Biofilms can both be beneficial or detrimental depending on the surface. Compared to their planktonic counterparts, biofilm cells display enhanced resistance to killing by environmental threats, chemicals, antimicrobials and host immune defenses. When in biofilms, the microbial cells interact with each other and with the surface to develop architecturally complex multi-dimensional structures. Numerous imaging techniques and tools are currently available for architectural analyses of biofilm communities. This allows examination of biofilm development through acquisition of three-dimensional images that can render structural features of the sessile community. A frequently ... [摘要]  生物膜是嵌入自生或宿主衍生的外聚合物基质中的微生物细胞的固着群落。根据表面,生物膜可以是有益的或有害的。与浮游生物相比,生物膜细胞表现出更强的抗环境威胁,化学物质,抗菌药物和宿主免疫防御能力。当处于生物膜中时,微生物细胞彼此相互作用并与表面相互作用以形成结构复杂的多维结构。目前,许多成像技术和工具可用于生物膜群落的建筑分析。这允许通过获取可以呈现无柄群落的结构特征的三维图像来检查生物膜的发展。经常使用的工具是共聚焦激光扫描显微镜。我们提出了一个详细的协议,以生长,观察和分析呼吸道人类病原体,百日咳博德特氏菌的生物膜在空间和时间。

【背景】百日咳博德特氏菌(Bordetella pertussis)是上呼吸道的专性人类病原体,引起百日咳或百日咳(Mooi,2010; Dorji et al。,2018)。 B的生物膜。百日咳在各种人造表面上以及静态,摇动和流体流动条件下形成(Mishra et al。,2005; Sloan et al。,2007 ; Serra et al。,2011)。对这些生物膜的显微评估表明,这种细菌产生不规则形状的微集落,由流体通道分隔,嵌入由细胞外DNA(eDNA),蛋白质和多糖组成的外聚合物基质中(Parise et al。,2007; Sloan et al。,2007; Serra et al。,2008; ...

[Abstract]  Brassinosteroids (BRs) promote rice lamina inclination. Recently, we showed that OsBUL1 knockout mutant rice (osbul1) is defective in brassinosteroid signaling (Jang et al., 2017). To show that lamina joint inclination of osbul1 is less-sensitive than WT to exogenous brassinolide (BL) treatment in the lamina joint inclination bioassays, we applied the protocol presented below. The protocol focuses on: (1) how to prepare rice samples for the assay, and (2) how to treat BL exogenously. Finally, we have added a result showing lamina inclination between WT and osbul1 in BL solutions of various concentrations. [摘要]  油菜素类固醇(BR)促进水稻倾角。 最近,我们显示,OsBUL1敲除突变体水稻(osbul1 )在油菜素内酯信号传导中有缺陷(Jang等人,2017)。 为了显示在层板关节倾斜生物测定中,osbul1 的椎板关节倾斜对外源油菜素内酯(BL)处理的敏感性低于WT,我们应用了下面提出的方案。 方案重点是:(1)如何准备水稻样品进行测定,以及(2)如何外源性处理BL。 最后,我们在不同浓度的BL溶液中添加了显示WT和osbul1 之间的椎板倾斜度的结果。
【背景】稻叶关节连接叶片和鞘,对叶角特征有显着贡献,BR是性状的主要调节因子,而其他植物激素(包括乙烯,赤霉素和生长素)也影响叶角(Gan et al。,2015)。更直立的叶片有助于阳光的渗透,提高光合作用效率,占据较少的密集种植空间(Sakamoto等人,2006)。因此,稻米倾角是影响水稻植物结构的主要农艺性状之一。实际上,Wada主要开发的稻米倾斜测定法,他的同事们是BR的高度特异性和敏感的生物测定(Wada等人,1981年和1984年)。在这种生物测定中,BR的处理相对于接合区域中的背轴细胞诱导更大的细胞扩增,导致层状倾斜(Takeno和Pharis,1982; ...
