    Extraction and 16S rRNA Sequence Analysis of Microbiomes Associated with Rice Roots
    Authors:  Joseph Edwards, Christian Santos-Medellín and Venkatesan Sundaresan, date: 06/20/2018, view: 13419, Q&A: 0
    [Abstract] Plant roots associate with a wide diversity of bacteria and archaea across the root-soil spectrum. The rhizosphere microbiota, the communities of microbes in the soil adjacent to the root, can contain up to 10 billion bacterial cells per gram of soil (Raynaud and Nunan, 2014) and can play important roles for the fitness of the host plant. Subsets ...
    TUNEL Assay to Assess Extent of DNA Fragmentation and Programmed Cell Death in Root Cells under Various Stress Conditions
    Authors:  Amit K. Tripathi, Ashwani Pareek and Sneh Lata Singla-Pareek, date: 08/20/2017, view: 12508, Q&A: 0
    [Abstract] DNA damage is one of the common consequences of exposure to various stress conditions. Different methods have been developed to accurately assess DNA damage and fragmentation in cells and tissues exposed to different stress agents. However, owing to the presence of firm cellulosic cell wall and phenolics, plant cells and tissues are not easily ...
    Rice Root Organic Acid Efflux Measurement by Using Ion Chromatography
    Authors:  Chun-quan Zhu, Xiao-fang Zhu and Ren-fang Shen, date: 02/20/2017, view: 7566, Q&A: 0
    [Abstract] Organic acids secreted from plant roots play important roles in various biological processes including nutrient acquisition, metal detoxification, and pathogen attraction. The secretion of organic acids may be affected by various conditions such as plant growth stage, nutrient deficiency, and abiotic stress. For example, when white lupin (Lupinus ...
    Measurement of H+ Flux in Rice by Non-invasive Micro-test Technology
    Authors:  Xi Zhang, Xiu-Yue Zhang and Li-Ping Yin, date: 12/05/2015, view: 8269, Q&A: 1
    [Abstract] Rice plants release proton (H+) from root cells into rhizosphere area leading to the acidification of the rhizosphere and increased solubility of ferric iron complexes on the cell membrane, which is important for iron uptakes. Here, we present a detailed protocol to measure H+ flux in root hairs of transgenic rice seedlings ...
    Measurement of Net NO3- Flux in Rice Plants with the SIET System
    Authors:  Zhong Tang and Guohua Xu, date: 08/20/2013, view: 7311, Q&A: 0
    [Abstract] SIET (scanning ion-electrode technique) is a new technique to study the flow rate of the ions and molecules in real time in living biomaterials by using microelectrodes and microsensor. This technique allows non-invasive, simultaneous measurement of fluxes of specific ions at the surface of an intact plant. It has high temporal and spatial ...
