    Histochemical Preparations to Depict the Structure of Cauliflower Leaf Hydathodes
    Authors:  Aude Cerutti, Marie-Christine Auriac, Laurent D. Noël and Alain Jauneau, date: 10/20/2017, view: 53, Q&A: 0
    [Abstract] Hydathodes are plant organs present on leaf margins of a wide range of vascular plants and are the sites of guttation. Both anatomy and physiology of hydathodes are poorly documented. We have recently reported on the anatomy of cauliflower and Arabidopsis thaliana hydathodes and on their infection by the vascular pathogenic bacterium ...
    Large-scale Maize Seedling Infection with Exserohilum turcicum in the Greenhouse
    Authors:  Ping Yang, Gerhard Herren, Simon G. Krattinger and Beat Keller, date: 10/05/2017, view: 353, Q&A: 0
    [Abstract] Northern corn leaf blight (NCLB) is a serious foliar disease of maize (Zea mays) worldwide and breeding for resistance is of primary importance for maize crop protection. Phenotyping for NCLB resistance is well established in the field, but such experiments depend on suitable environmental conditions and are seasonal. Here we describe a ...
    Xanthomonas oryzae pv. oryzae Inoculation and Growth Rate on Rice by Leaf Clipping Method
    Authors:  Yinggen Ke, Shugang Hui and Meng Yuan, date: 10/05/2017, view: 260, Q&A: 0
    [Abstract] Bacterial blight caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most serious bacterial diseases and a major impediment to the increase of rice yield. Appropriate methods for inoculation of Xoo and disease scoring are necessary to investigate the nature of the disease and the mechanism of plant ...
    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: 549, 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 ...
    Overrepresentation Analyses of Differentially Expressed Genes in the Smut Fungus Ustilago bromivora during Saprophytic and in planta Growth
    Authors:  Angelika Czedik-Eysenberg, Franziska Rabe, Heinz Ekker, Carmen Czepe and Armin Djamei, date: 08/05/2017, view: 529, Q&A: 0
    [Abstract] We have established the Ustilago bromivoraBrachypodium spp. interaction as a new model pathosystem for biotrophic fungal plant infections of the head smut type (Rabe et al., 2016). In this protocol, the methodology used for comparing gene expression between saprophytic and in planta growth of the fungus is ...
    Isolation of Ustilago bromivora Strains from Infected Spikelets through Spore Recovery and Germination
    Authors:  Jason Bosch and Armin Djamei, date: 07/20/2017, view: 611, Q&A: 0
    [Abstract] Ustilago bromivora is a biotrophic smut fungus infecting Brachypodium sp. It is closely related to the barley-infecting smut Ustilago hordei, and related to the well-studied, gall-inducing model pathogen Ustilago maydis. Upon flowering, the spikelets of U. bromivora-infected plants are filled with black ...
    Xanthoferrin Siderophore Estimation from the Cell-free Culture Supernatants of Different Xanthomonas Strains by HPLC
    [Abstract] Xanthomonads can scavenge iron from the extracellular environment by secreting the siderophores, which are synthesized by the proteins encoded by xss (Xanthomonas siderophore synthesis) gene cluster. The siderophore production varies among xanthomonads in response to a limited supply of iron where Xanthomonas ...
    A Simple and Rapid Assay for Measuring Phytoalexin Pisatin, an Indicator of Plant Defense Response in Pea (Pisum sativum L.)
    Authors:  Lee A. Hadwiger and Kiwamu Tanaka, date: 07/05/2017, view: 609, Q&A: 0
    [Abstract] Phytoalexins are antimicrobial substance synthesized in plants upon pathogen infection. Pisatin (Pisum sativum phytoalexin) is the major phytoalexin in pea, while it is also a valuable indicator of plant defense response. Pisatin can be quantitated in various methods from classical organic chemistry to ...
    Induction and Quantification of Patulin Production in Penicillium Species
    Authors:  Yong Chen, Boqiang Li, Zhanquan Zhang and Shiping Tian, date: 06/05/2017, view: 865, Q&A: 0
    [Abstract] Patulin, a worldwide regulated mycotoxin, is primarily produced by Penicillium and Aspergillus species during fruit spoilage. Patulin contamination is a great concern with regard to human health because exposure of the mycotoxin can result in severe acute and chronic toxicity, including neurotoxic, mutagenic, and immunotoxic ...
    Exopolysaccharide Quantification for the Plant Pathogen Ralstonia solanacearum
    Authors:  Rémi Peyraud, Timothy P. Denny and Stéphane Genin, date: 05/20/2017, view: 933, Q&A: 0
    [Abstract] Soluble exopolysaccharide is a major virulence factor produced by the plant pathogen Ralstonia solanacearum. Its massive production during plant infection is associated with the arrest of water flow in xylem vessels leading eventually to plant death. The composition of this heavy macromolecule includes mainly N-acetylgalactosamine. Here ...
