    An Improved Bioassay to Study Arabidopsis Induced Systemic Resistance (ISR) Against Bacterial Pathogens and Insect Pests
    Authors:  Nicolás M. Cecchini, Yi Song, Suruchi Roychoudhry, Jean T. Greenberg and Cara H. Haney, date: 05/20/2019, view: 194, Q&A: 0
    [Abstract] The plant immune system is essential for plants to perceive and defend against bacterial, fungal and insect pests and pathogens. Induced systemic resistance (ISR) is a systemic immune response that occurs upon root colonization by beneficial microbes. A well-studied model for ISR is the association of specific beneficial strains of Pseudomonas ...
    An Innovative Approach to Study Ralstonia solanacearum Pathogenicity in 6 to 7 Days Old Tomato Seedlings by Root Dip Inoculation
    Authors:  Niraj Singh, Rahul Kumar and Suvendra Kumar Ray, date: 11/05/2018, view: 1208, Q&A: 0
    [Abstract] Ralstonia solanacearum (F1C1) is a Gram-negative plant pathogenic bacterium that causes lethal wilt disease in a wide range of plant species. This pathogen is very well known for its unpredictable behavior during infection and wilting its host. Because of its mysterious infection behavior, virulence and pathogenicity standardization are ...
    Measuring Secretion of Capsidiol in Leaf Tissues of Nicotiana benthamiana
    Authors:  Teruhiko Kuroyanagi, Maurizio Camagna and Daigo Takemoto, date: 08/05/2018, view: 1251, Q&A: 0
    [Abstract] Plant species produce a wide variety of antimicrobial metabolites to protect themselves against potential pathogens in natural environments. Phytoalexins are low molecular weight compounds produced by plants in response to attempted attacks of pathogens. Accumulation of phytoalexins in attacked plant tissues can inhibit the growth of penetrating ...
    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: 3713, 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 ...
    Analysis of Autophagic Activity Using ATG8 Lipidation Assay in Arabidopsis thaliana
    Authors:  Mengqian Luo and Xiaohong Zhuang, date: 06/20/2018, view: 2051, Q&A: 0
    [Abstract] As a fundamental metabolic pathway to degrade and recycle cellular cargos, autophagy is highly induced upon stress, starvation and senescence conditions in plants. A double-membrane structure named autophagosome will form during this process for cargo sequestration and delivery into the vacuole.

    A number of regulators have been ...
    Protocol for RYMV Inoculation and Resistance Evaluation in Rice Seedlings
    Authors:  Agnès Pinel-Galzi, Eugénie Hébrard, Oumar Traoré, Drissa Silué and Laurence Albar, date: 06/05/2018, view: 1758, Q&A: 0
    [Abstract] Rice yellow mottle virus (RYMV), a mechanically transmitted virus that causes serious damage to cultivated rice plants, is endemic to Africa. Varietal selection for resistance is considered to be the most effective and sustainable management strategy. Standardized resistance evaluation procedures are required for the identification and ...
    Quantification of Salicylic Acid (SA) and SA-glucosides in Arabidopsis thaliana
    [Abstract] Homeostasis between the cytoplasmic plant hormone salicylic acid (SA) and its’ inactive, vacuolar storage forms, SA-2-O-β-D-glucoside (SAG) and SA-β-D-Glucose Ester (SGE), regulates the fine-tuning of defense responses to biotrophic pathogens in Arabidopsis thaliana. This protocol describes a simplified, optimized procedure to ...
    Rapid Screening and Evaluation of Maize Seedling Resistance to Stalk Rot Caused by Fusarium spp.
    Authors:  Yali Sun, Xinsen Ruan, Liang Ma, Fang Wang and Xiquan Gao, date: 05/20/2018, view: 2144, Q&A: 0
    [Abstract] Corn stalk rot caused by Fusarium spp., a genus of soil-borne fungal pathogens, has become a major concern of maize production. This disease normally causes significant reduction of maize yield and quality worldwide. The field assay for identifying stalk rot resistance using adult plants is largely relying on large population, yet ...
    Infection Process Observation of Magnaporthe oryzae on Barley Leaves
    Author:  Xiao-Lin Chen, date: 05/05/2018, view: 2427, Q&A: 0
    [Abstract] Rice blast and wheat blast caused by Magnaporthe oryzae is a serious threat to rice and wheat production. Appropriate methods for observing M. oryzae infection process are important for study of the fungal infection mechanisms, plant resistance reactions, and host-M. oryzae interactions. The rice leaf sheath is commonly ...
    Functional Evaluation of the Signal Peptides of Secreted Proteins
    Authors:  Weixiao Yin, Yufu Wang, Tao Chen, Yang Lin and Chaoxi Luo, date: 05/05/2018, view: 2135, Q&A: 2
    [Abstract] Here, we describe a method that can be used to evaluate the function of predicted signal peptides. This method utilizes the yeast Saccharomyces cerevisiae YTK12 strain and pSUC2 vector in which the pSUC2 vector with fused predicted signal peptide is transformed into yeast. The function of the signal peptides can be evaluated by using ...
