    Histochemical Preparations to Depict the Structure of Cauliflower Leaf Hydathodes
    Authors:  Aude Cerutti, Marie-Christine Auriac, Laurent D. Noël and Alain Jauneau, date: 10/20/2017, view: 19, Q&A: 0
    [Abstract] Hydathodes are plant organs present on leaf margins of a wide range of vascular plants and are the sites of guttation. Both anatomy and physiology of hydathodes are poorly documented. We have recently reported on the anatomy of cauliflower and Arabidopsis thaliana hydathodes and on their infection by the vascular pathogenic bacterium ...
    Capturing Z-stacked Confocal Images of Living Bacteria Entering Hydathode Pores of Cauliflower
    Authors:  Aude Cerutti and Alain Jauneau, date: 10/20/2017, view: 31, Q&A: 0
    [Abstract] The present protocol to visualize living bacteria at the pore level of cauliflower hydathodes is simple and trained users in confocal microscopy can execute it successfully. It can be easily adapted to capture images with other plant-microorganism interactions at the leaf surface and should be useful to obtain important information on pore and ...
    Scanning Electron Microscopy of Motile Male Gametes of Land Plants
    Authors:  Karen Sue Renzaglia, Renee A. Lopez and Steven J. Schmitt, date: 10/05/2017, view: 245, Q&A: 0
    [Abstract] The only motile cells produced in land plants are male gametes (spermatozoids), which are reduced to non-flagellated cells in flowering plants and most gymnosperms. Although a coiled architecture is universal, the complexity of land plant flagellated cells varies from biflagellated in bryophytes to thousands of flagella per gametes in the seed ...
    Transmission Electron Microscopy of Centrioles, Basal Bodies and Flagella in Motile Male Gametes of Land Plants
    [Abstract] Motile male gametes (spermatozoids) of land plants are coiled and contain a modified and precisely organized complement of organelles that includes a locomotory apparatus with two to thousands of flagella. Each flagellum is generated from a basal body that originates de novo as a centriole in spermatogenous cell lineages. Much of what is ...
    Quantification of Membrane Damage/Cell Death Using Evan’s Blue Staining Technique
    [Abstract] Membrane damage is a hallmark of both biotic and abiotic stress responses. The membrane determines the ability of a cell to sustain altered environmental conditions and hence can be used as a biomarker to assess stress-induced cell damage or death. We present an easy, quick, cost-effective, staining and spectrophotometric method to assess membrane ...
    Phototaxis Assay for Chlamydomonas reinhardtii
    Authors:  Noriko Ueki and Ken-ichi Wakabayashi, date: 06/20/2017, view: 1020, Q&A: 0
    [Abstract] Phototaxis is a behavior in which organisms move toward or away from the light source (positive or negative phototaxis, respectively). It is crucial for phototrophic microorganisms to inhabit under proper light conditions for phototaxis. The unicellular green alga Chlamydomonas reinhardtii rapidly changes its swimming direction upon light ...
    Analysis of 3D Cellular Organization of Fixed Plant Tissues Using a User-guided Platform for Image Segmentation
    Authors:  Ethel Mendocilla Sato and Célia Baroux, date: 06/20/2017, view: 937, Q&A: 0
    [Abstract] The advent of non-invasive, high-resolution microscopy imaging techniques and computational pipelines for high-throughput image processing has contributed to gain insights in plant organ morphogenesis at the cellular level. Confocal scanning laser microscopy (CSLM) allows the generation of three dimensional images constituted of serial optical ...
    Photometric Assays for Chloroplast Movement Responses to Blue Light
    [Abstract] Assessment of chloroplast movements by measuring changes in leaf transmittance is discussed, with special reference to the conditions necessary for reliable estimation of blue light–activated chloroplast responses.
    Resin-embedded Thin-section Immunohistochemistry Coupled with Triple Cellular Counterstaining
    Authors:  William M Palmer, John W Patrick and Yong-Ling Ruan, date: 04/05/2017, view: 819, Q&A: 0
    [Abstract] This protocol was developed to study protein localisation within the vascular bundles of developing tomato fruit however, it can be applied to any resin embedded plant tissue. The vascular bundle is comprised of many different cells that all have unique properties. The mature sieve elements are enucleated and contain sieve plates that comprise of ...
    Laser Scanning Confocal Microcopy for Arabidopsis Epidermal, Mesophyll, and Vascular Parenchyma Cells
    Authors:  Christian Elowsky, Yashitola Wamboldt and Sally Mackenzie, date: 03/05/2017, view: 1679, Q&A: 0
    [Abstract] Investigation of protein targeting to plastids in plants by confocal laser scanning microscopy (CLSM) can be complicated by numerous sources of artifact, ranging from misinterpretations from in vivo protein over-expression, false fluorescence in cells under stress, and organellar mis-identification. Our studies have focused on the ...
