    Bacterial Infection and Hypersensitive Response Assays in Arabidopsis-Pseudomonas syringae Pathosystem
    Authors:  Minhang Yuan and Xiu-Fang Xin, date: 12/20/2021, view: 1186, Q&A: 0
    [Abstract]

    Arabidopsis thaliana-Pseudomonas syringae pathosystem has been used as an important model system for studying plant-microbe interactions, leading to many milestones and breakthroughs in the understanding of plant immune system and pathogenesis mechanisms. Bacterial infection and plant disease assessment are key experiments in the studies of

    A Spectrofluorophotometrical Method Based on Fura-2-AM Probe to Determine Cytosolic Ca2+ Level in Pseudomonas syringae Complex Bacterial Cells
    [Abstract]

    Calcium signaling is an emerging mechanism by which bacteria respond to environmental cues. To measure the intracellular free-calcium concentration in bacterial cells, [Ca2+]i, a simple spectrofluorometric method based on the chemical probe Fura 2-acetoxy methyl ester (Fura 2-AM) is here presented using Pseudomonad bacterial cells. This is an

    Biofilm Formation Assay in Pseudomonas syringae
    Authors:  Xiaolong Shao, Yingpeng Xie, Yingchao Zhang and Xin Deng, date: 05/20/2019, view: 9243, Q&A: 1
    [Abstract] Pseudomonas syringae is a model plant pathogen that infects more than 50 plant species worldwide, thus leading to significant yield loss. Pseudomonas biofilm always adheres to the surfaces of medical devices or host cells, thereby contributing to infection. Biofilm formation can be visualized on numerous matrixes, including ...
    In planta Transcriptome Analysis of Pseudomonas syringae
    Authors:  Tatsuya Nobori and Kenichi Tsuda, date: 09/05/2018, view: 7018, Q&A: 0
    [Abstract] Profiling bacterial transcriptome in planta is challenging due to the low abundance of bacterial RNA in infected plant tissues. Here, we describe a protocol to profile transcriptome of a foliar bacterial pathogen, Pseudomonas syringae pv. tomato DC3000, in the leaves of Arabidopsis thaliana at an early stage of ...
    Surface Inoculation and Quantification of Pseudomonas syringae Population in the Arabidopsis Leaf Apoplast
    Authors:  Cristián Jacob, Shweta Panchal and Maeli Melotto, date: 03/05/2017, view: 11521, Q&A: 1
    [Abstract] Bacterial pathogens must enter the plant tissue in order to cause a successful infection. Foliar bacterial pathogens that are not able to directly penetrate the plant epidermis rely on wounds or natural openings to internalize leaves. This protocol describes a procedure to estimate the population size of Pseudomonas syringae in the leaf ...
    An HPLC-based Method to Quantify Coronatine Production by Bacteria
    Authors:  Shweta Panchal, Zachary S. Breitbach and Maeli Melotto, date: 03/05/2017, view: 7712, Q&A: 0
    [Abstract] Coronatine is a polyketide phytotoxin produced by several pathovars of the plant pathogenic bacterium Pseudomonas syringae. It is one of the most important virulence factors determining the success of bacterial pathogenesis in the plant at both epiphytic and endophytic stages of the disease cycle. This protocol describes an optimized ...
    Pseudomonas syringae Flood-inoculation Method in Arabidopsis
    Authors:  Yasuhiro Ishiga, Takako Ishiga, Yuki Ichinose and Kirankumar S. Mysore, date: 01/20/2017, view: 10657, Q&A: 0
    [Abstract] Pseudomonas syringae pv. tomato strain DC3000 (Pto DC3000), which causes bacterial speck disease of tomato, has been used as a model pathogen because of its pathogenicity on Arabidopsis thaliana. Here, we demonstrate a rapid and reliable flood-inoculation method based on young Arabidopsis seedlings ...
    In vitro DNA Polymerization Activity Assay Using Cell-free Extracts
    Authors:  Anurag K. Sinha and Malay K. Ray, date: 08/20/2014, view: 7976, Q&A: 0
    [Abstract] This protocol has been designed to measure the in-vitro DNA polymerization activity in crude cell extracts of the Antarctic bacterium Pseudomonas syrinagae Lz4W. This bacterium can grow at 4 °C with optimum growth rate at 22 °C. The slow growth rate of the bacterium observed at low temperature (4 °C) compared to higher ...
