Quantification of Blumenol Derivatives as Leaf Biomarkers for Plant-AMF Association
[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, ...
GC-MS-Based Analysis of Methanol: Chloroform-extracted Fatty Acids from Plant Tissues
[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 ...
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 ...
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
[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 ...
