Community Structures of Arbuscular Mycorrhizal Fungi in Soils and Plant Roots Inhabiting Abandoned Mines of Korea
In this study, we collected rhizosphere soils and root samples from a post-mining area and a natural forest area in Jecheon, Korea. We extracted spores of arbuscular mycorrhizal fungi (AMF) from rhizospheres, and then examined the sequences of 18S rDNA genes of the AMF from the collected roots of plants. We compared the AMF communities in the post-mining area and the natural forest area by sequ...
متن کاملGrowth 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...
متن کاملOrder of arrival structures arbuscular mycorrhizal colonization of plants.
Priority effects - the impact of a species' arrival on subsequent community development - have been shown to influence species composition in many organisms. Whether priority effects among arbuscular mycorrhizal fungi (AMF) structure fungal root communities is not well understood. Here, we investigated whether priority effects influence the success of two closely related AMF species (Rhizophagu...
متن کاملLinking root traits to nutrient foraging in arbuscular mycorrhizal trees in a temperate forest.
The identification of plant functional traits that can be linked to ecosystem processes is of wide interest, especially for predicting vegetational responses to climate change. Root diameter of the finest absorptive roots may be one plant trait that has wide significance. Do species with relatively thick absorptive roots forage in nutrient-rich patches differently from species with relatively f...
متن کاملArbuscular mycorrhizal associations in Lycopodiaceae.
This study characterizes the molecular and phylogenetic identity of fungi involved in arbuscular mycorrhizal (AM) associations in extant Huperzia and Lycopodium (Lycopodiaceae). Huperzia and Lycopodium are characterized by a life cycle with long-lived autotrophic sporophytes and long-lived mycoheterotrophic (obtain all organic carbon from fungal symbionts) gametophytes. 18S ribosomal DNA was is...
