    Maintenance and Quantitative Phenotyping of the Oomycete-plant Model Pathosystem Hyaloperonospora arabidopsidisArabidopsis
    Authors:  Fang-Yu Hwu and Martin Parniske, date: 06/20/2020, view: 436, Q&A: 0
    The interaction between the host plant Arabidopsis thaliana (Arabidopsis) and the oomycete Hyaloperonospora arabidopsidis (Hpa) is an established model system for the study of an obligate biotrophic downy mildew ...
    Maintenance and Quantitative Phenotyping of the Oomycete-plant Model Pathosystem Hyaloperonospora arabidopsidisArabidopsis
    Authors:  Fang-Yu Hwu and Martin Parniske, date: 06/20/2020, view: 436, Q&A: 0
    [Abstract] The interaction between the host plant Arabidopsis thaliana (Arabidopsis) and the oomycete Hyaloperonospora arabidopsidis (Hpa) is an established model system for the study of an obligate biotrophic downy mildew interaction. The evaluation of the developmental success of Hpa is often based on the quantification ...
    Determination of Ureides Content in Plant Tissues
    Author:  Ignacio Lescano, date: 06/05/2020, view: 575, Q&A: 0
    [Abstract] The ureides allantoin and allantoate are the main organic nitrogen compounds transported in several legumes, predominantly from N2 fixation. Moreover, recent studies point out a remarkable role for allantoin during several stress responses of plants other than legumes. The goal of this protocol is to determine ureides concentration in ...
    Safe DNA-extraction Protocol Suitable for Studying Tree-fungus Interactions
    Authors:  Susanna Keriö, Eeva Terhonen and Jared M. LeBoldus, date: 06/05/2020, view: 953, Q&A: 0
    [Abstract] We present a safe and low-cost method suitable for DNA extraction from mycelium and tree tissue samples. After sample preparation, the extraction takes about 60 min. Method performance was tested by extracting DNA from various tree tissue samples and from mycelium grown on solid and liquid media. DNA was extracted from juvenile and mature host ...
    Live Cell Imaging of Male Meiosis in Arabidopsis by a Landmark-based System
    [Abstract] Live cell imaging has tremendously promoted our understanding of cellular and subcellular processes such as cell division. Here, we present a step-by-step protocol for a robust and easy-to-use live cell imaging approach to study male meiosis in the plant Arabidopsis thaliana as recently established. Our method relies on the concomitant ...
    MAMP-triggered Medium Alkalinization of Plant Cell Cultures
    [Abstract] Plants recognize a wide variety of microbial molecules to detect and respond to potential invaders. Recognition of Microbe-Associated Molecular Patterns (MAMPs) by cell surface receptors initiate a cascade of biochemical responses that include, among others, ion fluxes across the plasma membrane. A consequence of such event is a decrease in the ...
    Accelerated Snowmelt Protocol to Simulate Climate Change Induced Impacts on Snowpack Dependent Ecosystems
    [Abstract] Field studies that simulate the effects of climate change are important for a predictive understanding of ecosystem responses to a changing environment. Among many concerns, regional warming can result in advanced timing of spring snowmelt in snowpack dependent ecosystems, which could lead to longer snow-free periods and drier summer soils. Past ...
    High-resolution and Deep Phylogenetic Reconstruction of Ancestral States from Large Transcriptomic Data Sets
    Authors:  Sumanth Kumar Mutte and Dolf Weijers, date: 03/20/2020, view: 829, Q&A: 0
    [Abstract] Phylogenetics is an important area of evolutionary biology that helps to understand the origin and divergence of genes, genomes and species. Building meaningful phylogenetic trees is needed for the accurate reconstruction of the past. To achieve a correct phylogenetic understanding of genes or proteins, reliable and robust methods are needed to ...
    Experiments for in silico evaluation of Optimality of Photosynthetic Nitrogen Distribution and Partitioning in the Canopy: an Example Using Greenhouse Cucumber Plants
    Authors:  Yi-Chen Pao, Tsu-Wei Chen, Dany Pascal Moualeu-Ngangue and Hartmut Stützel, date: 03/20/2020, view: 755, Q&A: 0
    [Abstract] Acclimation of leaf traits to fluctuating environments is a key mechanism to maximize fitness. One of the most important strategies in acclimation to changing light is to maintain efficient utilization of nitrogen in the photosynthetic apparatus by continuous modifications of between-leaf distribution along the canopy depth and within-leaf ...
    Single-run HPLC Quantification of Plant Cell Wall Monosaccharides
    [Abstract] The plant cell wall is a complex network of polysaccharides and proteins that provides strength and structural integrity to plant cells, as well as playing a vital role in growth, development, and defense response. Cell wall polysaccharides can be broadly grouped into three categories: cellulose, pectins, and hemicelluloses. Dynamic interactions ...
    Insect Feeding Assays with Spodoptera exigua on Arabidopsis thaliana
    Authors:  Yanrong You, Chunpeng An and Chuanyou Li, date: 03/05/2020, view: 718, Q&A: 0
    [Abstract] Plant-insect interaction is an important field for studying plant immunity. The beet armyworm, Spodoptera exigua, is one of the best-known agricultural pest insects and is usually used to study plant interactions with chewing insects. Here, we describe a protocol for insect feeding assays with Spodoptera exigua lavae using model ...
