Nitrate reducing capacity of two vesicular-arbuscular mycorrhizal fungi.

Growth model for arbuscular mycorrhizal fungi

In order to quantify the contribution of arbuscular mycorrhizal (AM) fungi to plant phosphorus nutrition, the development and extent of the external fungal mycelium and its nutrient uptake capacity are of particular importance. We develop and analyse a model of the growth of AM fungi associated with plant roots, suitable for describing mechanistically the effects of the fungi on solute uptake b...

Interactions between Soil Bacteria and Arbuscular Mycorrhizal Fungi

Toljander, J.F. 2006. Interactions between Soil Bacteria and Arbuscular Mycorrhizal Fungi. Doctoral dissertation. ISSN 1652-6880, ISBN 91-576-7088-9 The extraradical mycelium (ERM) of mycorrhizal fungi constitutes an important pathway for the translocation of energy-rich photoassimilates from plant to soil. Because of the large surface of the mycelium, and its provision of carbon, the ERM poten...

Biodiversity of arbuscular mycorrhizal fungi in agroecosystems

Arbuscular mycorrhizal fungi [AMF] are soil fungi which form a mutualistic symbiosis with the roots of plants. A variety of benefits to the host have been ascribed to mycorrhizae, most often enhanced uptake of immobile nutrients from the soil, notably P. An understanding of the impacts of agronomic practices upon communities of these fungi would help to ensure an opportunity for the utilization...
