Trapping AM fungi can be used to obtain many healthy spores of colonizing fungi for identification, as inoculum to establish monospecific cultures, or for experiments. Spores collected directly from field soil suffer from many problems: (a) they appear healthy but are not viable (some persisting as dead husks for years or ... Currently INVAM uses Sudangrass (Sorghum × drummondii) as a suitable host plant for our cultures. Some species of mycorrhizae may benefit from being cultured with ecosystem-specific host plants. The Bever-Schultz lab also use highly responsive perennial prairie plants (Koziol & Bever 2015) to grow native prairie-sourced mycorrhizal strains.The mission of INVAM is to acquire, propagate, characterize and maintain germplasm of arbuscular mycorrhizal fungi in living cultures for preservation and distribution to any person or institution eBook , English , 199u Mycorrhizae. Fungal structures in a mycorrhizal root cannot be seen without differential staining. Once that is done, then comes the task of measuring the extent of mycorrhizal colonization or other variables, some of which are discussed here. The photo above shows typical arbuscular development in a corn root colonized by Dentiscutata ... Germinating Spores. Germinating spores of R. clarus, either singly or in pairs (below) Rhizophagus clarus, like some other glomoid species, produces intercalary and terminal swellings that do not appear to develop into spores. Some spores produce abundant branch hyphae directly from the emergent germ tube (far right photo).INVAM will not be involved in publication of new species descriptions unless specific written arrangements are made with the contributor.
