A mycorrhiza is a 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.
An arbuscular mycorrhiza (AM) is a type of mycorrhiza in which the symbiont fungus penetrates the cortical cells of the roots of a vascular plant forming arbuscules.
Glomeromycota are one of eight currently recognized divisions within the kingdom Fungi, with approximately 230 described species. Members of the Glomeromycota form arbuscular mycorrhizas (AMs) with the thalli of bryophytes and the roots of vascular land plants. Not all species have been shown to form AMs, and one, Geosiphon pyriformis, is known not to do so. Instead, it forms an endocytobiotic association with Nostoc cyanobacteria. The majority of evidence shows that the Glomeromycota are dependent on land plants for carbon and energy, but there is recent circumstantial evidence that some species may be able to lead an independent existence. The arbuscular mycorrhizal species are terrestrial and widely distributed in soils worldwide where they form symbioses with the roots of the majority of plant species (>80%). They can also be found in wetlands, including salt-marshes, and associated with epiphytic plants.
Glomus aggregatum is an arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture. Like other species in this phylum it forms obligate symbioses with plant roots, where it obtains carbon (photosynthate) from the host plant in exchange for nutrients and other benefits.
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.
Phytopharmacology is the study and practice of eradicating plant pathology originated from the Verbandes Deutscher Pflanzenärzte (1928–1939),, headed by Otto Appel, known as the Organiser of German Plant Protection, who initially defined the terminology of Phyto-Medicine or Plant Medicine. The Deutsche Phytomedizinische Gesellschaft is the German association of phytomedicine practitioners. Academic programs in phytomedicine, such as at the University of Hohenheim, consider the interrelationships between pathogenic microorganisms and crops, disease control methods, and research programs.
Microbial inoculants also known as soil inoculants or bioinoculants are agricultural amendments that use beneficial rhizosphericic or endophytic microbes to promote plant health. Many of the microbes involved form symbiotic relationships with the target crops where both parties benefit (mutualism). While microbial inoculants are applied to improve plant nutrition, they can also be used to promote plant growth by stimulating plant hormone production. Although bacterial and fungal inoculants are common, inoculation with archaea to promote plant growth is being increasingly studied.
Julius Kühn-Institut – Bundesforschungsinstitut für Kulturpflanzen (JKI) is the German Federal Research Centre for Cultivated Plants. It is a federal research institute and a higher federal authority divided into 15 specialized institutes. Its objectives, mission and research scope were determined by section 11, paragraph 57 of the 1987 Federal Law on the Protection of Cultivated Plants as subsequently amended.
Acaulospora is a genus of fungi in the family Acaulosporaceae. Species in this genus are widespread in distribution, and form arbuscular mycorrhiza and vesicles in roots.
An ectomycorrhiza is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture.
A bioeffector is a viable microorganism or active natural compound which directly or indirectly affects plant performance (biofertilizer), and thus has the potential to reduce fertilizer and pesticide use in crop production.
Rhizophagus irregularis is an arbuscular mycorrhizal fungus used as a soil inoculant in agriculture and horticulture. Rhizophagus irregularis is also commonly used in scientific studies of the effects of arbuscular mycorrhizal fungi on plant and soil improvement. Until 2001, the species was known and widely marketed as Glomus intraradices, but molecular analysis of ribosomal DNA led to the reclassification of all arbuscular fungi from Zygomycota phylum to the Glomeromycota phylum.
Georg Friedrich Backhaus is a German agricultural scientist specializing in horticulture and phytomedicine. Since 2008 he has been president of the Julius Kühn-Institut (JKI) with headquarters in Quedlinburg.
The German Phytomedicine Society (DPG) is the professional association of practitioners of phytomedicine, as successor to the Association of German Plant Physicians that was based in Berlin from 1928 to 1937. The DPG was founded in 1949 in Fulda. The DPG headquarters is located in Braunschweig.
The International Association for the Plant Protection Sciences (IAPPS) has the goal of gathering the results of plant protection research worldwide and making them globally available to science and practice. To this end the organisation periodically publishes the Plant Protection Magazine and every four years organises an international congress, the latest of which took place in Berlin
Sarah Elizabeth Smith was a British-born Australian mycologist specialising in mycorrhiza. The Australian Academy of Science described her as "a world authority on the mycorrhizal symbiosis between plants and fungi". She was an adjunct and emeritus professor at the University of Adelaide, in the School of Agriculture, Food and Wine.
Markus Weinmann is an agricultural scientist specialising in the area of Plant Physiology at the University of Hohenheim, and ranks as one of the pioneers of Bioeffector-Research aimed at improving plant growth, vitality and disease resistance. He is also coordinator of field experiments in the EU-Biofector-Project.
Mycorrhizal amelioration of heavy metals or pollutants is a process by which mycorrhizal fungi in a mutualistic relationship with plants can sequester toxic compounds from the environment, as a form of bioremediation.
Dr. Mohamed Hijri is a biologist who studies arbuscular mycorrhizal fungi (AMF). He is a professor of biology and research at the Institut de recherche en biologie végétale at the University of Montreal.
The International Collection of (Vesicular) Arbuscular Mycorrhizal Fungi (INVAM) is the largest collection of living arbuscular mycorrhizal fungi (AMF) and includes Glomeromycotan species from 6 continents. Curators of INVAM acquire, grow, identify, and elucidate the biology, taxonomy, and ecology of a diversity AMF with the mission to expand availability and knowledge of these symbiotic fungi. Culturing AMF presents difficulty as these fungi are obligate biotrophs that must complete their life cycle while in association with their plant hosts, while resting spores outside of the host are vulnerable to predation and degradation. Curators of INVAM have thus developed methods to overcome these challenges to increase the availability of AMF spores. The inception of this living collection of germplasm occurred in the 1980s and it takes the form of fungi growing in association with plant symbionts in the greenhouse, with spores preserved in cold storage within their associated rhizosphere. AMF spores acquired from INVAM have been used extensively in both basic and applied research projects in the fields of ecology, evolutionary biology, agroecology, and in restoration. INVAM is umbrellaed under the Kansas Biological Survey at The University of Kansas, an R1 Research Institution. The Kansas Biological Survey is also home to the well-known organization Monarch Watch. INVAM is currently located within the tallgrass prairie ecoregion, and many collaborators and researchers associated with INVAM study the role of AMF in the mediation of prairie biodiversity. James Bever and Peggy Schultz are the Curator and Director of Operation team, with Elizabeth Koziol and Terra Lubin as Associate Curators.
