Authors: Chaopei Dong, Yabin Wu, Jingyang Gao, Zijian Zhou, Cong Mu, Peipei Ma, Jiafa Chen and Jianyu Wu, date: 12/05/2018, view: 931, 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 ...

Preparation and Purification of Proteins Secreted from Phytophthora sojae

Authors: Yeqiang Xia, Yan Wang and Yuanchao Wang, date: 10/20/2018, view: 1274, Q&A: 0

[Abstract] Phytophthora sojae, the causal agent of soybean root and stem rot, is responsible for enormous economic losses in soybean production. P. sojae secrets various effectors to reprogram host immunity. The plant apoplastic space is a major battleground in plant-pathogen interactions. Here we describe a protocol for purification and ...

Artificial Inoculation of Epichloë festucae into Lolium perenne, and Visualisation of Endophytic and Epiphyllous Fungal Growth

Authors: Yvonne Becker, Kimberly A. Green, Barry Scott and Matthias Becker, date: 09/05/2018, view: 1442, Q&A: 0

[Abstract] Natural hosts for the fungal endophyte Epichloë festucae include Festuca rubra (fine fescue) and Festuca trachyphylla (hard fescue). Some strains also form stable associations with Lolium perenne (perennial ryegrass). L. perenne is a suitable host to study fungal endophyte–grass interactions, such as endophytic ...

In vivo and in vitro ³¹P-NMR Study of the Phosphate Transport and Polyphosphate Metabolism in Hebeloma cylindrosporum in Response to Plant Roots Signals

Authors: Christine Le Guernevé, Adeline Becquer, Margarita Torres-Aquino, Laurie K Amenc, Carlos Trives-Segura, Siobhan Staunton, Claude Plassard and Hervé Quiquampoix, date: 08/20/2018, view: 1227, Q&A: 0

[Abstract] We used in vivo and in vitro phosphorus-31 nuclear magnetic resonance (³¹P-NMR) spectroscopy to follow the change in transport, compartmentation and metabolism of phosphate in the ectomycorrhizal fungus Hebeloma cylindrosporum in response to root signals originating from host (Pinus pinaster) or ...

Fusarium graminearum Inoculation on Wheat Head

Authors: Chanjing Feng, Huiquan Liu and Zhe Tang, date: 08/05/2018, view: 1737, 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 ...

Infection Process Observation of Magnaporthe oryzae on Barley Leaves

Author: Xiao-Lin Chen, date: 05/05/2018, view: 2433, 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 ...

Tracking Lipid Transfer by Fatty Acid Isotopolog Profiling from Host Plants to Arbuscular Mycorrhiza Fungi

Authors: Andreas Keymer, Claudia Huber, Wolfgang Eisenreich and Caroline Gutjahr, date: 04/05/2018, view: 2236, Q&A: 0

[Abstract] Lipid transfer from host plants to arbuscular mycorrhiza fungi was hypothesized for several years because sequenced arbuscular mycorrhiza fungal genomes lack genes encoding cytosolic fatty acid synthase (Wewer et al., 2014; Rich et al., 2017). It was finally shown by two independent experimental approaches (Jiang et al., ...

Establishing a Symbiotic Interface between Cultured Ectomycorrhizal Fungi and Plants to Follow Fungal Phosphate Metabolism

Authors: Adeline Becquer, Margarita Torres-Aquino, Christine Le Guernevé, Laurie K Amenc, Carlos Trives-Segura, Siobhan Staunton, Hervé Quiquampoix and Claude Plassard, date: 10/20/2017, view: 3082, Q&A: 0

[Abstract] In ectomycorrhizal plants, the fungal cells colonize the roots of their host plant to create new organs called ectomycorrhizae. In these new organs, the fungal cells colonize the walls of the cortical cells, bathing in the same apoplasm as the plant cells in a space named the ‘Hartig net’, where exchanges between the two partners take place. ...

A Method for Radioactive Labelling of Hebeloma cylindrosporum to Study Plant-fungus Interactions

Authors: Adeline Becquer, Margarita Torres-Aquino, Christine Le Guernevé, Laurie K Amenc, Carlos Trives-Segura, Siobhan Staunton, Hervé Quiquampoix and Claude Plassard, date: 10/20/2017, view: 3172, Q&A: 0

[Abstract] In order to quantify P accumulation and P efflux in the ectomycorrhizal basidiomycete fungus Hebeloma cylindrosporum, we supplied ³²P to mycelia previously grown in vitro in liquid medium. The culture had four main steps that are 1) growing the mycelium on complete medium with P, 2) transfer the mycelia into new ...

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: 4149, 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 ...
