    Imaging Gene Expression Dynamics in Pseudomonas fluorescens In5 during Interactions with the Fungus Fusarium graminearum PH-1
    Authors:  Rosanna C. Hennessy, Peter Stougaard and Stefan Olsson, date: 06/20/2019, view: 795, Q&A: 0
    [Abstract] Genomics, transcriptomics and metabolomics are powerful technologies for studying microbial interactions. The main drawback of these methods is the requirement for destructive sampling. We have established an alternative but complementary technique based on a microplate system combined with promoter fusions for visualizing gene expression in space ...
    Field Inoculation and Classification of Maize Ear Rot Caused by Fusarium verticillioides
    Authors:  Chaopei Dong, Yabin Wu, Jingyang Gao, Zijian Zhou, Cong Mu, Peipei Ma, Jiafa Chen and Jianyu Wu, date: 12/05/2018, view: 1610, Q&A: 0
    [Abstract] Maize ear rot is a worldwide fungal disease mainly caused by Fusarium verticillioides and Fusarium graminearum. Maize planted in the field was inoculated with Fusarium verticillioides at the filling stage, 15 days after pollination. Two milliliters of spore suspension with a concentration of 5 x 106/ml was ...
    Fusarium graminearum Inoculation on Wheat Head
    Authors:  Chanjing Feng, Huiquan Liu and Zhe Tang, date: 08/05/2018, view: 2641, Q&A: 0
    [Abstract] Fusarium graminearum, the major causal agent of Fusarium head blight (FHB), causes serious wheat yield losses and a threat to human and animal health. The main efforts to combat the disease are the research of pathogenesis mechanisms and breeding for disease resistance plants. The efficiency of these actions could be evaluated by ...
    Quantification of the Composition Dynamics of a Maize Root-associated Simplified Bacterial Community and Evaluation of Its Biological Control Effect
    Authors:  Ben Niu and Roberto Kolter, date: 06/20/2018, view: 3005, Q&A: 0
    [Abstract] Besides analyzing the composition and dynamics of microbial communities, plant microbiome research aims to understanding the mechanism of plant microbiota assembly and their biological functions. Here, we describe procedures to investigate the role of bacterial interspecies interactions in root microbiome assembly and the beneficial effects of the ...
    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: 2892, 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 ...
    Wheat Coleoptile Inoculation by Fusarium graminearum for Large-scale Phenotypic Analysis
    Authors:  Lei-Jie Jia, Wan-Qiu Wang and Wei-Hua Tang, date: 08/05/2017, view: 4993, Q&A: 0
    [Abstract] The ascomycete fungus Fusarium graminearum is a destructive fungal pathogen of wheat, barley and maize. Although reverse genetics and homologous recombination gene deletion methods have generated thousands of gene deletion mutants of F. graminearum, evaluating virulence of these fungal mutants is still a rate-limiting step. Here ...
    Wheat Root-dip Inoculation with Fusarium graminearum and Assessment of Root Rot Disease Severity
    Authors:  Qing Wang and Sven Gottwald, date: 03/20/2017, view: 5788, Q&A: 0
    [Abstract] Fusarium graminearum is one of the most common and potent fungal pathogens of wheat (Triticum aestivum) and other cereals, known for causing devastating yield losses and mycotoxin contaminations of food and feed. The pathogen is mainly considered as a paradigm for the floral disease Fusarium head blight, while its ability to ...
    Assessment of Wheat Resistance to Fusarium graminearum by Automated Image Analysis of Detached Leaves Assay
    Authors:  Alexandre Perochon and Fiona M. Doohan, date: 12/20/2016, view: 5787, Q&A: 0
    [Abstract] Fusarium head blight (FHB) caused by Fusarium pathogens is a globally important cereal disease. To study Fusarium pathogenicity and host disease resistance, robust methods for disease assessment and quantification are needed. Here we describe the procedure of a detached leaves assay emphasizing the image analysis. The ...
    Highly Accurate Real-time Measurement of Rapid Hydrogen-peroxide Dynamics in Fungi
    Authors:  Michael Mentges and Jörg Bormann, date: 12/20/2016, view: 5444, Q&A: 0
    [Abstract] Reactive oxygen species (ROS) are unavoidable by-products of aerobic metabolism. Despite beneficial aspects as a signaling molecule, ROS are principally recognized as harmful agents that act on nucleic acids, proteins and lipids. Reactive oxygen species, and, in particular, hydrogen peroxide (H2O2), are deployed as defense ...
    Fusarium graminearum Maize Stalk Infection Assay and Associated Microscopic Observation Protocol
    Authors:  Juan He, Tinglu Yuan and Wei-Hua Tang, date: 12/05/2016, view: 6114, Q&A: 0
    [Abstract] The ascomycete fungus Fusarium graminearum (previously also called Gibberella zeae) causes Gibberella stalk rot in maize (Zea mays) and results in lodging and serious yield reduction. To develop methods to assess the fungal growth and symptom development in maize stalks, we present here a protocol of maize stalk ...
