    Spatiotemporal Quantification of Cytosolic pH in Arabidopsis Pollen Tubes
    Authors:  Maria Teresa Portes, Daniel S.C. Damineli and José A. Feijó, date: 07/20/2021, view: 120, Q&A: 0
    [Abstract]

    Ion-specific probes and fluorescent indicators have been key in establishing the role of ion signaling, namely calcium, protons, and anions, in plant development, providing a robust approach for monitoring spatiotemporal changes in intracellular ion dynamics. The integration of protons/pH in signaling mechanisms is especially important as reports

    Rice Root Hair Phenotypes Imaged by Cryo-SEM
    [Abstract]

    Cryo-scanning electron microscopy (cryo-SEM) was first introduced for scientific use in the 1980s. Since then, cryo-SEM has become a routine technique for studying the surfaces and internal structures of biological samples with a high water content. In contrast to traditional SEM, cryo-SEM requires no sample pretreatment processes; thus, we can

    Age, Wound Size and Position of Injury – Dependent Vascular Regeneration Assay in Growing Leaves
    [Abstract]

    Recurring damage to the aerial organs of plants necessitates their prompt repair, particularly their vasculature. While vascular regeneration assays for aerial plant parts such as the stem and inflorescence stalk are well established, those for leaf vasculature remain unexplored. Recently, we established a new vascular regeneration assay in

    Histochemical Staining of Suberin in Plant Roots
    Authors:  Peter Marhavý and Shahid Siddique, date: 02/05/2021, view: 1894, Q&A: 0
    [Abstract]

    Histological stains are useful tools for characterizing cell shape, arrangement and the material they are made from. Stains can be used individually or simultaneously to mark different cell structures or polymers within the same cells, and to visualize them in different colors. Histological stains can be combined with genetically-encoded

    Measuring Extracellular Proton and Anionic Fluxes in Arabidopsis Pollen Tubes
    Authors:  Maria Teresa Portes and José A. Feijó, date: 02/05/2021, view: 2014, Q&A: 0
    [Abstract]

    The ion-selective vibrating probe has been used to detect and quantify the magnitude and direction of transmembrane fluxes of several ions in a wide range of biological systems. Inherently non-invasive, vibrating probes have been essential to access relevant electrophysiological parameters related to apical growth and morphogenesis in pollen

    Development and Standardization of Rapid and Efficient Seed Germination Protocol for Cannabis sativa
    Authors:  Aleksei Sorokin, Narendra Singh Yadav, Daniel Gaudet and Igor Kovalchuk, date: 01/05/2021, view: 1427, Q&A: 0
    [Abstract]

    Cannabis seed germination is an important process for growers and researchers alike. Many biotechnological applications require a reliable sterile method for seed germination. This protocol outlines a seed germination procedure for Cannabis sativa using a hydrogen peroxide (H2O2) solution as liquid germination media. In this protocol, all three

    A Pulse–chase EdU Method for Detection of Cell Division Orientation in Arabidopsis and Juncus prismatocarpus Leaf Primordia
    Authors:  Xiaofeng Yin and Hirokazu Tsukaya, date: 01/05/2021, view: 1089, 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 ...
    Gene Expression and Genome Editing Systems by Direct Delivery of Macromolecules Into Rice Egg Cells and Zygotes
    Authors:  Erika Toda and Takashi Okamoto, date: 07/20/2020, view: 1539, Q&A: 0
    [Abstract] Polyethylene glycol calcium (PEG-Ca2+)-mediated transfection allows rapid and efficient examination to analyze diverse cellular functions of genes of interest. In plant cells, macromolecules, such as DNA, RNA and protein, are delivered into protoplasts derived from somatic tissues or calli via PEG-Ca2+ transfection. To ...
    Transient Expression Assay in Strawberry Fruits
    Authors:  Mengting Pi, Qi Gao and Chunying Kang, date: 06/05/2019, view: 4498, Q&A: 0
    [Abstract] Strawberry, including the woodland strawberry Fragaria vesca (2x) and the cultivated strawberry (Fragaria × ananassa, 8x), has emerged as a model system for studying fruit development and ripening. Transient expression provides a quick assay for gene functions or gene interactions. In strawberry, ...
    Visualization of Plant Cell Wall Epitopes Using Immunogold Labeling for Electron Microscopy
    Author:  Mateusz Majda, date: 04/05/2019, view: 4205, Q&A: 0
    [Abstract] Plant cell walls consist of different polysaccharides and structural proteins, which form a rigid layer located outside of the plasma membrane. The wall is also a very dynamic cell composite, which is characterized by complex polysaccharide interactions and various modifications during cell development. The visualization of cell wall components in ...
