    [Abstract]

    Analyzing cellular structures and the relative location of molecules is essential for addressing biological questions. Super-resolution microscopy techniques that bypass the light diffraction limit have become increasingly popular to study cellular molecule dynamics in situ. However, the application of super-resolution imaging techniques to detect

    [Abstract]

    Plant nanobiotechnology is a flourishing field that uses nanomaterials to study and engineer plant function. Applications of nanotechnology in plants have great potential as tools for improving crop yield, tolerance to disease and environmental stress, agrochemical delivery of pesticides and fertilizers, and genetic modification and transformation

    A Pulse–chase EdU Method for Detection of Cell Division Orientation in Arabidopsis and Juncus prismatocarpus Leaf Primordia
    脉冲追踪EdU法检测拟南芥和笄石菖叶原基细胞分裂方向
    作者:Xiaofeng Yin and Hirokazu Tsukaya日期:01/05/2021,浏览量:1385,Q&A: 0
    [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 ...
    Lipid Droplet Isolation from Arabidopsis thaliana Leaves
    拟南芥叶脂滴的分离

    [Abstract]

    Lipid droplets (LDs) are neutral lipid aggregates surrounded by a phospholipid monolayer and specific proteins. In plants, they play a key role as energy source after seed germination, but are also formed in vegetative tissues in response to developmental or environmental conditions, where their functions are poorly understood. To elucidate these,

    Acidified Blue Ink-staining Procedure for the Observation of Fungal Structures Inside Roots of Two Disparate Plant Lineages
    两个不同植物谱系根内真菌结构的酸化蓝墨水染色法观察流程
    作者:Jill Kowal, Elena Arrigoni and Sophie Lane日期:10/20/2020,浏览量:1559,Q&A: 0
    [Abstract] Identifying microscopic mycorrhizal fungal structures in roots, i.e., hyphae, vesicles and arbuscules, requires root staining procedures that are often time consuming and involves chemicals known to present health risks from exposure. By modifying established protocols, our root staining method stains roots using a safe ink- and ...
    Multitarget Immunohistochemistry for Confocal and Super-resolution Imaging of Plant Cell Wall Polysaccharides
    植物细胞壁多糖共聚焦和超分辨成像的多靶点免疫组织化学研究
    作者:Kalina T. Haas, Methieu Rivière, Raymond Wightman and Alexis Peaucelle日期:10/05/2020,浏览量:2916,Q&A: 0
    [Abstract] The plant cell wall (PCW) is a pecto-cellulosic extracellular matrix that envelopes the plant cell. By integrating extra-and intra-cellular cues, PCW mediates a plethora of essential physiological functions. Notably, it permits controlled and oriented tissue growth by tuning its local mechano-chemical properties. To refine our knowledge of these ...
    Live Cell Imaging of Male Meiosis in Arabidopsis by a Landmark-based System
    地标系统在拟南芥雄性减数分裂活体细胞成像中的应用
    作者:Maria Ada Prusicki, Emma Mathilde Keizer, Rik Peter van Rosmalen, Christian Fleck and Arp Schnittger日期:05/05/2020,浏览量:3404,Q&A: 0
    [Abstract] Live cell imaging has tremendously promoted our understanding of cellular and subcellular processes such as cell division. Here, we present a step-by-step protocol for a robust and easy-to-use live cell imaging approach to study male meiosis in the plant Arabidopsis thaliana as recently established. Our method relies on the concomitant ...
    Quantification of Protein Enrichment at Plasmodesmata
    胞间连丝富集蛋白的量化分析
    作者:Magali S. Grison, Jules D. Petit, Marie Glavier and Emmanuelle M. Bayer日期:03/05/2020,浏览量:2567,Q&A: 0
    [Abstract] Intercellular communication plays a crucial role in the establishment of multicellular organisms by organizing and coordinating growth, development and defence responses. In plants, cell-to-cell communication takes place through nanometric membrane channels called plasmodesmata (PD). Understanding how PD dictate cellular connectivity greatly ...
    Tandem Tag Assay Optimized for Semi-automated in vivo Autophagic Activity Measurement in Arabidopsis thaliana roots
    优化的串联标签检测用于拟南芥根组织中体内半自动化自噬活性测定
    作者:Adrian N. Dauphinee, Jonas A. Ohlsson and Elena A. Minina日期:03/05/2020,浏览量:2847,Q&A: 0
    [Abstract] Autophagy is the main catabolic process in eukaryotes and plays a key role in cell homeostasis. In vivo measurement of autophagic activity (flux) is a powerful tool for investigating the role of the pathway in organism development and stress responses. Here we describe a significant optimization of the tandem tag assay for detection of ...
    Visualization of Actin Organization and Quantification in Fixed Arabidopsis Pollen Grains and Tubes
    固定拟南芥花粉粒及花粉管中肌动蛋白组织可视化及定量分析
    作者:Xiaolu Qu, Qiannan Wang, Haiyan Wang and Shanjin Huang日期:01/05/2020,浏览量:2680,Q&A: 0
    [Abstract] Although it is widely accepted that actin plays an important role in regulating pollen germination and pollen tube growth, how actin exactly performs functions remains incompletely understood. As the function of actin is dictated by its spatial organization, it is the key to reveal how exactly actin distributes in space in pollen cells. Here we ...
