Ciri utama FMA adalah terdapatnya arbuskular di dalam korteks akar. Awalnya fungi tumbuh di antara sel-sel korteks, kemudian menembus dinding sel inang dan berkembang di dalam sel (Brundrett et al.1996). Klasifikasi FMA menurut INVAM (2009) dapat dilihat pada Tabel 1. Sedangkan perkembangan dan taksonomi FMA dapat dilihat pada Gambar 1. Tabel 1. The nomenclatural type material of Rhizophagus intraradices (basionym Glomus intraradices) was originally described from a trap pot culture established with root fragments, subcultures of which later became registered in the INVAM culture collection as FL 208. Subcultures of FL 208 (designated as strain ATT 4) and a new strain, independently ...Glomalin Extraction (.pdf) explains these methods. A sodium pyrophosphate extraction is the harshest and recovers the most soluble pool (easily extractable) as well as the total protein pool (total glomalin). Each of these latter pools can be extracted using different concentrations of sodium citrate and varying the length of autoclaving.MPN Value. The MPN value is determined from counts of positive tubes (those with mycorrhizae) in different dilutions. The first dilution to be measured is the lowest one with the maximum number of positive tubes (usually 5 in an assay with 5 tubes per dilution), along with the next two dilutions. The number of positive tubes in each of these ...

Mycorrhizal inoculum was acquired from INVAM (West Virginia University, Morgantown, WV, USA). Half of the inoculum (14 g) was mixed into the potting mix, and the other half was added directly to the seedling transfer site at the top. In the fertilizer experiment, 105.6 mg of P (960 mg fertilizer) was added to half of the pots at the …Please note the viewing of Documents is not accessable at this time.

A new glomeromycotan fungus, Archaeospora ecuadoriana sp. nov., was found in the south Ecuadorian mountain rainforest region, a global plant biodiversity hotspot. It was cultivated as single spore isolate originating from nursery-grown native tree seedlings inoculated with mixed soil from pristine forest and agricultural fields. The new species is …Emeritus professor of plant pathology, West Virginia University, Davis College of Agriculture, Natural Resources & Design Curator of INVAM at WVU.

Within 30 days of harvest, a rating of sporulation abundance is assigned to each active culture in the collection. We use this is relative measure as an indicator of culture productivity (see notes section of the searcheable culture database) and it has served us well for over a decade. Total mycorrhizal root length = R2 + R3. Total plant root length can be estimated by substituting R1 for R2 in the same set of calculations. This estimate is valid only if the root architecture in the small sample (which usually consists of only fine roots) resembles that of the rest of the root system—the large sample. All visits to INVAM must be preceded by an email query to [email protected] with follow-up communications. All visitors pay a bench fee, scaled for length of stay. These fees are necessary to offset expenses associated with loss of time in fulfilling core INVAM activities as well as other research and teaching responsibilities at KU.
