2024 Invam - 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.

ProsesOct 16, 2023 · In terrestrial ecosystems, arbuscular mycorrhizal fungi (AMF) help land plants in nutrient uptake and protect them against biotic and abiotic stresses. It is important to study the AMF-plant relationships to fully realize the beneficial potential of AMF to support establishment, growth and maintenance of mycorrhizal plants in different ecosystems. …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).L1: An outer permanent rigid layer with tightly packed short rounded warts 1.0-2.5 µm high, pale brown (0-20-50-10) in color.

Some isolates in INVAM are consistently white, but the spores are at the small end of the size distribution, others are highly variable in color (changing with pot culture generation), and still others are mostly yellow to yellow-brown. This continuum eliminates any morphological distinction between R. clarus and Rhizophagus manihotis.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.
