A mycorrhiza is a mutual symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology and soil chemistry.
Halomonadaceae is a family of halophilic Proteobacteria.
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, including boreal forests, bogs, and heathlands. Molecular clock estimates suggest that the symbiosis originated approximately 140 million years ago.
Helotiales is an order of the class Leotiomycetes within the division Ascomycota. According to a 2008 estimate, the order contains 10 families, 501 genera, and 3881 species.
Xerocomus is a genus of poroid fungi related to Boletus. Many mycologists did not originally recognize the distinction between the two genera and placed Xerocomus taxa in genus Boletus. However, several molecular phylogenetic studies have demonstrated that Xerocomus is a heterogeneous genus of polyphyletic origin, which has resulted in further division of Xerocomus into Xerocomellus and Hemileccinum. The members of the genus Xerocomellus are more closely related to Boletus than true Xerocomus is, which is relatively distantly related to Boletus and more closely related to Phylloporus. Other former Xerocomus species have since been moved to Aureoboletus, Imleria, Hortiboletus and Rheubarbariboletus.
Boletopsis is a genus of mycorrhizal fungi in the family Bankeraceae. The genus was circumscribed by Swiss mycologist Victor Fayod in 1889, with Boletopsis leucomelaena as the type species.
Austroboletus is a genus of fungi in the family Boletaceae. The widely distributed genus contains 28 species that form mycorrhizal relationships with plants.
Fistulinella is a genus of bolete fungi in the family Boletaceae. The genus has a pantropical distribution, and contains 15 species. Fistulinella was circumscribed by German mycologist Paul Christoph Hennings in 1901.
Naïs is a genus of fungi in the family Halosphaeriaceae. The genus, which contains two species, was circumscribed by mycologist Jan Kohlmeyer in 1962 to contain Naïs inornata. N. aquatica was described from submerged wood collected in north Queensland, Australia in 1992.
Tomentella is a genus of corticioid fungi in the family Thelephoraceae. The genus is ectomycorrhizal, and widespread, with about 80 species according to a 2008 estimate, although many new species have since been described. Tomentella was circumscribed by French mycologist Narcisse Théophile Patouillard in 1887.
Sebacina is a genus of fungi in the family Sebacinaceae. Its species are mycorrhizal, forming a range of associations with trees, orchids, and other plants. Basidiocarps are produced on soil and litter, sometimes partly encrusting stems of living plants. The fruit bodies are cartilaginous to rubbery-gelatinous and variously effused to coral-shaped. The genus has a cosmopolitan distribution, but fewer than a dozen species are currently recognized worldwide.
The mycorrhizosphere is the region around a mycorrhizal fungus in which nutrients released from the fungus increase the microbial population and its activities. 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 with its plant host. The fungus in turn benefits by receiving photosynthetic sugars from its host. The mycorrhizosphere consists of roots, hyphae of the directly connected mycorrhizal fungi, associated microorganisms, and the soil in their direct influence.
Pseudogymnoascus is a genus of fungi in the family Pseudeurotiaceae.
James Martin Trappe is a mycologist and expert in the field of North American truffle species. He has authored or co-authored 450 scientific papers and written three books on the subject. MycoBank lists him as either author or co-author of 401 individual species, and over the course of his career he has helped guide research on mycorrhizal fungi, and reshaped truffle taxonomy: establishing a new order, two new families, and 40 individual genera.
Dark septate endophytes (DSE) are a group of endophytic fungi characterized by their morphology of melanized, septate, hyphae. This group is likely paraphyletic, and contain conidial as well as sterile fungi that colonize roots intracellularly or intercellularly. Very little is known about the number of fungal taxa within this group, but all are in the Ascomycota. They are found in over 600 plant species and across 114 families of angiosperms and gymnosperms and co-occur with other types of mycorrhizal fungi. They have a wide global distribution and can be more abundant in stressed environments. Much of their taxonomy, physiology, and ecology are unknown.
John William Gibson Cairney (1959–2012) was an eminent Scottish–Australian mycologist and Director of the UWS Centre for Plants and the Environment. Cairney specialised in mycorrhizal biology and ecology, particularly of ericoid- and Ectomycorrhiza. Cairney contributed significantly to mycorrhizal research, publishing over 150 manuscripts and serving as the associate editor, editor or on the advisoral panel for numerous scientific journals including: New Phytologist, Plant and Soil, Mycological Research and the Journal of Soils and Sediments.
Leifiporia is a genus of two species of poroid white rot crust fungi in the family Polyporaceae. The genus was circumscribed by Chinese mycologists in 2016 to accommodate the type species Leifiporia rhizomorpha.
Mycorrhizae and changing climate refers to the effects of climate change on mycorrhizae, a fungus which forms an endosymbiotic relationship between with a vascular host plant by colonizing its roots, and the effects brought on by climate change. Climate change is any lasting effect in weather or temperature. It is important to note that a good indicator of climate change is global warming, though the two are not analogous. However, temperature plays a very important role in all ecosystems on Earth, especially those with high counts of mycorrhiza in soil biota.
Candidatus "Glomeribacter gigasporarum" is a gram-negative β-proteobacteria. The bacterium is rod-shaped, and has a obligate endosymbiotic relationship with the arbuscular-mycorrhizal fungi Gigaspora margarita. Sequencing of the16S rRNA gene places Ca. "G. gigasporarum" within the Burkholderia genus. Ca. "G. gigasporarum is unculturable as of yet, but can stay alive in enrichment for up to 4 weeks. The candidate bacteria is considered "the smallest beta-proteobacterium" with a genome size of 1.4 Mb. The chromosome is 750 kb long and a plasmid is 600 to 650 kb. The genome size was determined using gel-electrophoresis.
Halovibrio variabilis is a Gram-negative, aerobic, mesophilic and heterotrophic bacterium from the genus of Halovibrio.
