Description
This is a freeze-fracture preparation of a root of grass with endomycorrhiza. The fungus hyphae (bright grey) enter the root and penetrate into the cells. Arbuscular mycorrhizas are found in 85% of all plant families, and occur in many crop species. The mycorrhizal fungi have a much greater ability to obtain minerals and water from the soil than plants themselves. Often also nitrogen and phosphate supply of the plants is improved if a fungus is involved. For their part, they receive part of the assimilates produced by the photosynthesis of the plants. Mycorrhization offers some protection against root pathogens and above-ground pests, such as aphids or harmful fungal infections. In addition, it also increases the dry resistance of plants, which can be particularly beneficial in extreme locations. Scanning Electron Microscope, magnification 700x (at 15cm image width).
