    Tracking Root Interactions System (TRIS) Experiment and Quality Control
    Authors:  Hassan Massalha, Elisa Korenblum, Orr H. Shapiro and Asaph Aharoni, date: 04/20/2019, view: 29, Q&A: 0
    Soil organisms are diverse taxonomically and functionally. This ecosystem experiences highly complex networks of interactions, but may also present functionally independent entities. Plant roots, a metabolically active hotspot in the soil, take an ...
    Tracking Root Interactions System (TRIS) Experiment and Quality Control
    Authors:  Hassan Massalha, Elisa Korenblum, Orr H. Shapiro and Asaph Aharoni, date: 04/20/2019, view: 29, Q&A: 0
    [Abstract] Soil organisms are diverse taxonomically and functionally. This ecosystem experiences highly complex networks of interactions, but may also present functionally independent entities. Plant roots, a metabolically active hotspot in the soil, take an essential part in shaping the rhizosphere. Tracking the dynamics of root-microbe interactions at high ...
    Quantification of the Humidity Effect on HR by Ion Leakage Assay
    Authors:  Musoki Mwimba and Xinnian Dong, date: 04/05/2019, view: 154, Q&A: 0
    [Abstract] We describe a protocol to measure the contribution of humidity on cell death during the effector-triggered immunity (ETI), the plant immune response triggered by the recognition of pathogen effectors by plant resistance genes. This protocol quantifies tissue cell death by measuring ion leakage due to loss of membrane integrity during the ...
    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 ...
    Extraction and Purification of Laccases from Rice Stems
    Authors:  Chenna Swetha and P. V. Shivaprasad, date: 04/05/2019, view: 172, Q&A: 0
    [Abstract] Laccases are found in cell walls of plants in very low amounts. This protocol provides an efficient method to purify laccases from rice stems. The method involves three steps: 1) Isolation of total protein from rice stems using buffers with high salt concentration to extract protein from cell walls; 2) Purification of laccases using concanavalin-A ...
    Quantitative Plasmodesmata Permeability Assay for Pavement Cells of Arabidopsis Leaves
    Authors:  Min Diao, Qiannan Wang and Shanjin Huang, date: 04/05/2019, view: 318, Q&A: 0
    [Abstract] Plasmodesmata (PD) are intercellular channels between walled plant cells that enable the transportation of materials between adjacent cells, which are important for plant growth and development. The permeability of PD must be tightly regulated. Assays to determine the permeability of PD are crucial for related studies on the regulation of PD ...
    Multiple Modification of Chromosomal Loci Using URA5.3 Selection Marker in the Unicellular Red Alga Cyanidioschyzon merolae
    Authors:  Tokiaki Takemura, Sousuke Imamura, Yuki Kobayashi and Kan Tanaka, date: 04/05/2019, view: 174, Q&A: 0
    [Abstract] The unicellular red alga Cyanidioschyzon merolae has been used as a eukaryotic photosynthetic model for various basic and applied studies. Although the nuclear genome of C. merolae can be modified by homologous recombination with exogenously introduced DNA, it has been difficult to modify multiple chromosome loci within the same ...
    Peptide Feeding and Mechanical Wounding for Tomato Seedlings
    Authors:  Lei Wang, Yan Wang and Georg Felix, date: 03/20/2019, view: 635, Q&A: 0
    [Abstract] Plants need to respond appropriately to wounding and herbivorous insects. Peptide signals have been implicated in local and systemic induction of appropriate plant defense responses. To study these peptide signals and their perception in host plants, it is important to have reproducible bioassays. Several assays, such as treatment of peptide ...
    Measuring and Imaging the Soil-root-water System with a Light Transmission 2D Technique
    Authors:  Claude Doussan and Emmanuelle Garrigues, date: 03/20/2019, view: 457, Q&A: 0
    [Abstract] Improving crops against water deficits requires a better understanding of plant root system functioning. This requires a better knowledge of the water uptake process and to address the influence of root system architecture or root physiological properties on the uptake efficiency. To this end, we describe here a non-destructive system that enables ...
    Detection of Disulfides in Protein Extracts of Arabidopsis thaliana Using Monobromobimane (mBB)
    Authors:  Shin‐nosuke Hashida and Maki Kawai-Yamada, date: 03/05/2019, view: 464, Q&A: 0
    [Abstract] Thiol-disulfide exchange is a key posttranslational modification, determining the folding process of intra- and inter-protein structures. Thiols can be detected by colorimetric reagents, which are stoichiometrically reduced by free thiols, and by fluorescent adducts, showing fluorescence only after thioester formation. We adapted a simple ...
    Quantification of Serotonin in Rice and Insect Pest and its Functional Analysis in Insects Using Artificial Diet Feeding
    Authors:  Long Wang, Xiaohao Guo, Wenqian Huang, Haiping Lu and Qing-yao Shu, date: 02/20/2019, view: 483, Q&A: 0
    [Abstract] Rice is one of the world’s most important crops, but its production suffers from insect pests. Rice brown planthopper (BPH; Nilaparvata lugens Stål) and striped stem borer (SSB, Chilo suppressalis Walker) are the two most serious pests in rice production. We reported that serotonin is an essential mediator in the interaction ...
