    Authors:  Nergiz Gürbüz Çolak, Neslihan Tek Eken, Anne Frary and Sami Doğanlar, date: 03/05/2021, view: 12, Q&A: 0

    Targeted metabolomics is a useful approach to evaluate crop breeding studies. Antioxidant and flavor-related traits are of increasing interest and are considered quality traits in tomato breeding. The present study presents chromatographic methods

    Phytophthora infestans (Late blight) Infection Assay in a Detached Leaf of Potato
    Authors:  Hari S. Karki and Dennis A. Halterman, date: 02/20/2021, view: 650, Q&A: 0

    Phytophthora infestans is a hemibiotroph oomycete that primarily infects potato and tomato. It infects stems, leaves, and tubers and fruits of potato and tomato. High throughput and reproducible infection assays are prerequisites to find sources of

    Phytophthora infestans (Late blight) Infection Assay in a Detached Leaf of Potato
    Authors:  Hari S. Karki and Dennis A. Halterman, date: 02/20/2021, view: 650, Q&A: 0
    [Abstract]

    Phytophthora infestans is a hemibiotroph oomycete that primarily infects potato and tomato. It infects stems, leaves, and tubers and fruits of potato and tomato. High throughput and reproducible infection assays are prerequisites to find sources of resistance in any crop. In this protocol, we describe a detached leaf assay (DLA) for conducting the

    A Pipeline for Non-model Organisms for de novo Transcriptome Assembly, Annotation, and Gene Ontology Analysis Using Open Tools: Case Study with Scots Pine
    Authors:  Gustavo T. Duarte, Polina Yu. Volkova and Stanislav A. Geras’kin, date: 02/05/2021, view: 473, Q&A: 0
    [Abstract]

    RNA sequencing (RNA-seq) has opened up the possibility of studying virtually any organism at the whole transcriptome level. Nevertheless, the absence of a sequenced and accurately annotated reference genome may be an obstacle for applying this technique to non-model organisms, especially for those with a complex genome. While de novo transcriptome

    Plant ARGONAUTE Protein Immunopurification for Pathogen Cross Kingdom Small RNA Analysis
    Authors:  Florian Dunker, Bernhard Lederer and Arne Weiberg, date: 02/05/2021, view: 352, Q&A: 0
    [Abstract]

    Over the last decade, it has been noticed that microbial pathogens and pests deliver small RNA (sRNA) effectors into their host plants to manipulate plant physiology and immunity for infection, known as cross kingdom RNA interference. In this process, fungal and oomycete parasite sRNAs hijack the plant ARGONAUTE (AGO)/RNA-induced silencing complex

    Measuring Extracellular Proton and Anionic Fluxes in Arabidopsis Pollen Tubes
    Authors:  Maria Teresa Portes and José A. Feijó, date: 02/05/2021, view: 215, 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

    Histochemical Staining of Suberin in Plant Roots
    Authors:  Peter Marhavý and Shahid Siddique, date: 02/05/2021, view: 421, 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

    Using 14C-acetate Pulse-chase Labeling to Study Fatty Acid and Glycerolipid Metabolism in Plant Leaves
    Authors:  Linhui Yu, Chao Zhou, Jilian Fan and Changcheng Xu, date: 02/05/2021, view: 294, Q&A: 0
    [Abstract]

    Lipids metabolism is comprised of networks of reactions occurred in different subcellular compartments. Isotopic labeling is a good way to track the transformations and movements of metabolites without perturbing overall cellular metabolism. Fatty acids, the building blocks of membrane lipids and storage triacylglycerols, are synthesized in

    Cellulase and Macerozyme-PEG-mediated Transformation of Moss Protoplasts
    [Abstract] This protocol describes the generation of protoplasts from protonemal tissue of the moss Physcomitrium patens (syn. Physcomitrella patens), using Cellulase ONOZUKA R10 and Macerozyme R10, followed by polyethylene glycol (PEG) mediated transformation. The protonemal tissue grown in liquid suspension was harvested and treated with ...
    Design and Construction of Repacked Soil Columns for Measuring Solute Transport, Plant Growth and Soil Biota
    Authors:  Israel Ikoyi and Achim Schmalenberger, date: 01/20/2021, view: 601, Q&A: 0
    [Abstract]

    Researchers face a number of challenges in the construction of soil columns which can affect the outcome of their experiments. The use of intact soil cores closely mimics actual field conditions. However, the excavation of large intact soil cores is a time-consuming, labor-intensive process and may lead to soil compaction that would influence the

    Efficient Transient Gene Knock-down in Tobacco Plants Using Carbon Nanocarriers
    Authors:  Gozde S. Demirer and Markita P. Landry, date: 01/05/2021, view: 813, Q&A: 0
    [Abstract] Gene knock-down in plants is a useful approach to study genotype-phenotype relationships, render disease resistance to crops, and enable efficient biosynthesis of molecules in plants. Small interfering RNA (siRNA)-mediated gene silencing is one of the most common ways to achieve gene knock-down in plants. Traditionally, siRNA is delivered into ...
    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: 497, 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 ...
