    Quantification of Blumenol Derivatives as Leaf Biomarkers for Plant-AMF Association
    Authors:  Elisabeth Mindt, Ming Wang, Martin Schäfer, Rayko Halitschke and Ian T. Baldwin, date: 07/20/2019, view: 600, Q&A: 0
    [Abstract] Symbiotic interactions between arbuscular mycorrhizal fungi (AMF) and plants are widespread among land plants and can be beneficial for both partners. The plant is provided with mineral nutrients such as nitrogen and phosphorous, whereas it provides carbon resources for the fungus in return. Due to the large economic and environmental impact, ...
    Determination of Root Exudate Concentration in the Rhizosphere Using 13C Labeling
    Authors:  Laurent Simon and Feth el Zahar Haichar, date: 05/05/2019, view: 913, Q&A: 0
    [Abstract] One of the most remarkable metabolic features of plant roots is their ability to secrete a wide range of compounds into the rhizosphere, defined as the volume of soil around living roots. Around 5%-21% of total photosynthetically fixed carbon is transferred into the rhizosphere through root exudates. Until recently, studies on the quantity and ...
    Measuring and Imaging the Soil-root-water System with a Light Transmission 2D Technique
    Authors:  Claude Doussan and Emmanuelle Garrigues, date: 03/20/2019, view: 1149, Q&A: 0
    [Abstract] Improving crops against water deficits requires a better understanding of plant root system functioning. This requires a better knowledge of the water uptake process and to address the influence of root system architecture or root physiological properties on the uptake efficiency. To this end, we describe here a non-destructive system that enables ...
    GC-MS-Based Analysis of Methanol: Chloroform-extracted Fatty Acids from Plant Tissues
    Authors:  Manish Kumar Patel, Shubhashis Das and Jitendra Kumar Thakur, date: 09/20/2018, view: 2934, Q&A: 0
    [Abstract] Fatty acids (FAs) are carboxylic acids with long aliphatic chains that may be straight, branched and saturated or unsaturated. Most of the naturally occurring plant FAs contains an even number of carbon (C4-C24). FAs are used in food and pharmacological industries due to their nutritional importance. In addition, FAs are considered as a promising ...
    An Inexpensive and Comprehensive Method to Examine and Quantify Field Insect Community Influenced by Host Plant Olfactory Cues
    Authors:  Rupesh Kariyat, Jesus Chavana and Jasleen Kaur, date: 08/20/2018, view: 1601, Q&A: 0
    [Abstract] Insect pollinators, herbivores and their natural enemies use olfactory cues emitted by their host plants to locate them. In insect-plant ecology, understanding the mechanisms underlying these interactions are of critical importance, as this bio-communication has both ecological and agricultural applications. However, the first step in such ...
    In situ Hybridization (ISH) in Preparasitic and Parasitic Stages of the Plant-parasitic Nematode Meloidogyne spp.
    [Abstract] The spatio-temporal expression pattern of a gene provides important indications to better understand its biological function. In situ hybridization (ISH) uses a labeled complementary single-stranded RNA or DNA probe to localize gene transcripts in a whole organism, a whole organ or a section of tissue. We adapted the ISH technique to the ...
    Automatic Leaf Epidermis Assessment Using Fourier Descriptors in Texture Images
    [Abstract] The identification of plant species is not a trivial task, since it is carried out by experts and depends on the presence of fruits, flowers and leaves. However, fruits and flowers are not available throughout the year, while leaves are accessible most of the year. In order to assist the specialized work of species identification, methods of ...
    Immunogold Localization of Molecular Constituents Associated with Basal Bodies, Flagella, and Extracellular Matrices in Male Gametes of Land Plants
    [Abstract] Male gametes (spermatozoids) are the only motile cells produced during the life cycle of land plants. While absent from flowering and most cone-bearing plants, motile cells are found in less derived taxa, including bryophytes (mosses, liverworts and hornworts), pteridophytes (lycophytes and ferns) and some seed plants (Ginkgo and cycads). ...
    Monitoring Xylem Hydraulic Pressure in Woody Plants
    [Abstract] Xylem sap circulates under either positive or negative hydraulic pressure in plants. Negative hydraulic pressure (i.e., tension) is the most common situation when transpiration is high, and several devices have been developed to quantify it accurately (e.g., Scholander pressure chamber, psychrometers). However, a proper ...
    Scanning Electron Microscopy of Motile Male Gametes of Land Plants
    Authors:  Karen Sue Renzaglia, Renee A. Lopez and Steven J. Schmitt, date: 10/05/2017, view: 3589, Q&A: 0
    [Abstract] The only motile cells produced in land plants are male gametes (spermatozoids), which are reduced to non-flagellated cells in flowering plants and most gymnosperms. Although a coiled architecture is universal, the complexity of land plant flagellated cells varies from biflagellated in bryophytes to thousands of flagella per gametes in the seed ...
