    Visualization of Plant Cell Wall Epitopes Using Immunogold Labeling for Electron Microscopy
    Author:  Mateusz Majda, date: 04/05/2019, view: 330, 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 ...
    Live Confocal Imaging of Brachypodium Spikelet Meristems
    Author:  Devin Lee O'Connor, date: 09/20/2018, view: 1207, Q&A: 0
    [Abstract] Live confocal imaging of fluorescent reporters and stains in plant meristems provides valuable measurements of gene expression, protein dynamics, cell polarity, cell division, and growth. The spikelet meristem in the grass Brachypodium distachyon (Brachypodium) is well suited to live imaging because of the ease of dissection, small ...
    Fabrication and Use of the Dual-Flow-RootChip for the Imaging of Arabidopsis Roots in Asymmetric Microenvironments
    [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 ...
    Pollen Germination and Pollen Tube Growth of Arabidopsis thaliana: In vitro and Semi in vivo Methods
    Authors:  Hugh Dickinson, Josefina Rodriguez-Enriquez and Robert Grant-Downton , date: 08/20/2018, view: 2528, Q&A: 0
    [Abstract] Studies of pollen germination and post-germination development are not only essential for understanding plant reproduction but also are an excellent model system for tip-based growth. Here we describe easy, reproducible methods for germination and growth of pollen from the model plant Arabidopsis thaliana in artificial conditions. Our ...
    A Modified Approach for Axenic Cultivation of Spores of Fern Adiantum capillus-veneris L. with High Germination Rate
    Authors:  Yuan Ya-Ning, Yi Shu, Jin Wan-Ting and Fang Yu-Han, date: 07/05/2018, view: 1167, Q&A: 0
    [Abstract] Spores are the primary way of spread and reproduction for ferns, a clade of seed-free vascular plants. However, no detailed protocol for ferns spore cultivation has been reported yet. Here we provide a modified approach for axenic cultivation of fern Adiantum capillus-veneris L., based on Cao’s and Li’s method (Cao, et al., 2010; ...
    Scanning Electron Microscope (SEM) Imaging to Determine Inflorescence Initiation and Development in Olive
    Authors:  Amnon Haberman, Einat Zelinger and Alon Samach, date: 10/05/2017, view: 3277, Q&A: 0
    [Abstract] Here we present a protocol that describes how to image the structure of the olive axillary bud meristem with a scanning electron microscope (SEM) in order to characterize its identity and developmental stage. Briefly, the specimen is fixed with glutaraldehyde, saturated with ethanol, dried in a critical point dryer (CPD) system, dissected, coated ...
    Comprehensive Methods for Leaf Geometric Morphometric Analyses
    Authors:  Laura L. Klein and Harlan T. Svoboda, date: 05/05/2017, view: 6686, Q&A: 0
    [Abstract] Leaf morphometrics are used frequently by several disciplines, including taxonomists, systematists, developmental biologists, morphologists, agronomists, and plant breeders to name just a few. Leaf shape is highly variable and can be used for identifying species or genotypes, developmental patterning within and among individuals, assessing plant ...
    Automated Tracking of Root for Confocal Time-lapse Imaging of Cellular Processes
    Authors:  Mehdi Doumane, Claire Lionnet, Vincent Bayle, Yvon Jaillais and Marie-Cécile Caillaud, date: 04/20/2017, view: 5076, Q&A: 0
    [Abstract] Here we describe a protocol that enables to automatically perform time-lapse imaging of growing root tips for several hours. Plants roots expressing fluorescent proteins or stained with dyes are imaged while they grow using automatic movement of the microscope stage that compensates for root growth and allows to follow a given region of the root ...
    In vitro Floral Induction of Cuscuta reflexa
    Authors:  Priyanka Das and Santilata Sahoo, date: 01/20/2017, view: 4009, Q&A: 0
    [Abstract] Floral initiation and development in the angiosperms is the essential step on which the yield of the plant depends. Sometimes external climate or any abiotic stress hinders the floral initiation and ultimately affect the plant yield. Hence, in vitro floral induction and development can help to overcome the external climatic factor. ...
    Shoot Apical Meristem Size Measurement
    Authors:  Hsuan Chou, Huanzhong Wang and Gerald A. Berkowitz, date: 12/05/2016, view: 4531, Q&A: 0
    [Abstract] The shoot apical meristem (SAM) is a collection of cells that continuously renew themselves by cell division and also provide cells to newly developing organs. It has been known that CLAVATA (CLV) 3 peptide regulates a transcription factor WUSCHEL (WUS) to keep numbers of undifferentiated cells constant and maintain the size of the SAM. The ...
