Cultures of a single species usually must be started from carefully selected spores. These spores can originate from a field soil if they are healthy and infective, but probability of success varies greatly with soil type, amount of organic matter, and sometimes environmental conditions or seasons. Success appears to be greatest with sandy low ...We identified spores to family level using morphological characteristics, with reference to the International Culture Collection of Arbuscular and Vesicular-Arbuscular Mycorrhizal Fungi (INVAM ...The term “mycorrhiza” was coined by A. B. Frank 1 which literally means ‘fungus-root’ and describes the mutualistic association existing between a group of soil fungi and higher plants. Arbuscular Mycorrhizal Fungi (AMF) form mutualistic symbioses with roots of over 80% of known plant species 2 including bryophyte, pteridophyte, gymnosperm and …Field study results were confirmed by growing seedlings under greenhouse conditions and inoculating them with Glomus intraradices Schenck and Smith (INVAM isolate KS906) and Gigaspora margarita Becker & Hall (INVAM isolate BR444–2). The AM fungi increased the growth and P contents of plants and the yield of castanospermine in the leaves ...

fine roots and soil from Glomus etunicatum (INVAM UT-316) stock pots containing sudangrass. Pots without VAM fungus re-ceived filtrate from a slurry of stock pot soil that had passed through a 43 lm sieve. Pots were then randomly positioned in a growth chamber and maintained on a 16:8 L:D schedule at 25°C.The most recent classification of Glomeromycota is based on a consensus of regions spanning ribosomal RNA genes: 18S (SSU), ITS1-5.8S-ITS2 (ITS), and/or 28S (LSU). The phylogenetic reconstruction underlying this classification is discussed and summarized in Redecker et al. (2013). The parts of the tree about which we agree (based on our LSU ...In the 1980’s, spore germination was examined in a wide range of mycorrhizal fungi. Methods included germinating spores on agar, on membranes above soil or soil solutions or in soils, and in root organ cultures. We study spore germination either for qualitative taxonomic analysis (to observe mode of germination) or to quantitatively examine ...

If hyphal growth is not evident but spores still clump ...

Maintenance of Long-Term Cultures. Some fungi require over six months to sporulate (such as sporocarpic species formerly in Sclerocystis).Others produce spores and other propagules which break-down rapidly in dry storage and therefore some or all of the stock material must be maintained in long-term cultures.
