A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules by photosynthesis and supplies them to the fungus in the form of sugars or lipids, while the fungus supplies the plant with water and mineral nutrients, such as phosphorus, taken from the soil.
The roots of most terrestrial plants, including most crop plants and almost all woody plants, are colonized by mycorrhiza-forming symbiotic fungi. In this relationship, the plant roots are infected by a fungus, but the rest of the fungal mycelium continues to grow through the soil, digesting and absorbing nutrients and water and sharing these ...
Arbuscular mycorrhizal networks are those in which fungal hyphae not only enter the plant's roots but also penetrate into the cells themselves. Ectomycorrhizal networks send hyphae into the roots where they thread their way between the plant cells but do not penetrate cell walls. The arbuscular type is the most common among land plants and is ...
The ericoid mycorrhiza is a mutualistic relationship formed between members of the plant family Ericaceae and several lineages of mycorrhizal fungi. This symbiosis represents an important adaptation to acidic and nutrient poor soils that species in the Ericaceae typically inhabit, [ 1 ] including boreal forests , bogs , and heathlands .
Apart from the unique peloton structures which transfer nitrogen and phosphorus from mycorrhizal fungi to orchid plants the transfer of these nutrients, as discussed above is almost identical to that observed in arbuscular mycorrhiza and ericoid mycorrhiza, but when it comes to arguably the most fundamental element involved in mycorrhizal ...
Arbuscular mycorrhizal fungi can provide numerous benefits to their plant hosts, including improved nutrient uptake, drought resistance, and disease resistance. However, the symbiosis is not mutualistic in all circumstances and may often be parasitic, with a detrimental effect on plant growth. Rarely, some plant species can parasitise the fungi ...
A single plant with its associated fungus is not an isolated entity. It has been shown that mycelia from the roots of one plant actually colonize the roots of nearby plants, creating an underground network of plants of the same or different species. This network is known as a common mycorrhizal network (CMN). It has been demonstrated that ...
Arbuscular mycorrhizal fungi are found in 80% of plant species [44] and have been surveyed on all continents except Antarctica. [45] [46] The biogeography of glomeromycota is influenced by dispersal limitation, [47] environmental factors such as climate, [45] soil series and soil pH, [46] soil nutrients [48] and plant community.
