[Abstract]  This protocol provides a detailed description of how to fabricate and use the dual-flow-RootChip (dfRootChip), a novel microfluidic platform for investigating root nutrition, root-microbe interactions and signaling and development in controlled asymmetric conditions. The dfRootChip was developed primarily to investigate how plants roots interact with their environment by simulating environmental heterogeneity. The goal of this protocol is to provide a detailed resource for researchers in the biological sciences wishing to employ the dfRootChip in particular, or microfluidic devices in general, in their laboratory. [摘要]  该协议提供了如何制造和使用双流RootChip(dfRootChip)的详细描述,这是一种新型微流体平台,用于研究根管营养,根 - 微生物相互作用以及受控不对称条件下的信号传导和发育。 dfRootChip的开发主要是为了研究植物根系如何通过模拟环境异质性与环境相互作用。 该协议的目标是为希望在其实验室中特别使用dfRootChip或一般微流体装置的生物科学研究人员提供详细资源。

【背景】地下条件是高度异质和动态的,因此植物根部暴露于各种刺激,因此必须适应这种复杂的环境。尽管这些发展适应的重要性,但潜在的机制仍有待阐明。微流体装置已被证明可用于在受控的微环境中培养标本,并有助于从亚细胞到有机物水平的动态过程的实时成像(Crane 等人,,2010)。由于微流体可以以受控方式操纵小流体体积,以高通量进行实验,提取定量信息并进行延时测量,微流体装置已经进入了有机体研究。对于模式植物拟南芥,已经开发了一系列微流体装置,能够在根发育过程中监测基因表达(Busch et al。,2012),信号事件(Keinath et al。,2015)和基于传感器的营养摄取成像(Grossmann et al。,2011; Lanquar et al。, 2014)。此外,使用微流体平台的最新进展包括高分辨率表型分析(Jiang et al。,2014; Xing ...

Non-invasive Protocol for Kinematic Monitoring of Root Growth under Infrared Light

[Abstract]  Phenotyping the dynamics of root responses to environmental cues is necessary to understand plant acclimation to their environment. Continuous monitoring of root growth is challenging because roots normally grow belowground and are very sensitive to their growth environment. This protocol combines infrared imaging with hydroponic cultivation for kinematic analyses. It allows continuous imaging at fine spatiotemporal resolution and disturbs roots minimally. Examples are provided of how the procedure and materials can be adapted for 3D monitoring and of how environmental stress may be manipulated for experimental purposes. [摘要]  对环境线索的根系反应动态进行表型分析是了解植物适应环境的必要条件。 持续监测根系生长是有挑战性的,因为根系通常生长在地下,对其生长环境非常敏感。 该方案将红外成像与水培培养相结合,用于运动学分析。 它允许在精细的时空分辨率下连续成像并最小化干扰根。 提供了如何将程序和材料适用于3D监测以及为实验目的如何操纵环境压力的实例。
【背景】运动学分析用于监测植物的生长和向性可以追溯到19世纪末期,早期研究从朱利叶斯·冯·萨克斯和惠尔普菲弗。 20世纪20年代以前摄影的广泛应用导致了通过“连拍摄影”(List of 1969; Erickson和Silk,1980)更容易和持续的监控。在90年代,新的数码相机和信息学工具使得能够开发用于粒子图像测速的自动跟踪算法。 RootFlowRT(Van der Weele等人,2003),Kineroot(Basu等人,2007),RootTrace(French et al。,et al。,& ...

[Abstract]  Potato cyst nematodes (PCNs; Globodera rostochiensis and G. pallida) are devastating pests that infect potato root. We describe an in vitro assay for PCN infection on potato plantlet in tissue culture. This method is useful for studying nematode parasitism on potato and for investigating responses of potato clones/lines to PCN infection. [摘要]  马铃薯胞囊线虫(PCNs; Globodera rostochiensis 和 G。pallida )是感染土豆根的毁灭性害虫。 我们描述了在组织培养的马铃薯小植株上的PCN感染的体外测定。 这种方法可用于研究马铃薯上的线虫寄生和调查马铃薯克隆/株系对PCN感染的反应。
