Trap Cultures. 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 ... May 1, 2017 · Arbuscular mycorrhizal fungi (AMF, subphylum Glomeromycotina) are symbionts of most terrestrial plants. They commonly harbour endobacteria of a largely unknown biology, referred to as MRE ( M ollicutes /mycoplasma-related endobacteria). Here, we propose to accommodate MRE in the novel genus ‘Candidatus Moeniiplasma.’ …These features were re-described by Kennedy et al. (1999) in order to clearly distinguish D. spurca from another species of similar morphology, D. eburnea. While these two species are similar, they can be readily distinguished with a practiced eye. Arizona workers (Kennedy, Stutz, and colleagues) as well as workers at INVAM have been able to ...INVAM is the International Culture Collection of Vesicular Arbuscular Mycorrhizal Fungi, West Virginia University, Morgantown, WV, USA.

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 ...

Gigasporaceae - Morton & Benny. Species in this family form large (usually >200 um) asexual spores with the following morphological properties: The spore wall consists of a permanent outer layer enclosing a laminate layer, each with different properties that distinguish species (e.g. color, thickness, reaction in Melzer’s reagent, etc.) and.Description: All known species produce spores without ornamentations. Spores consist of only a bilayered spore wall; germ tubes arise from a thin papillate (warty) layer arising from inner surface the laminate layer. Thin-walled auxiliary cells with echinulate surfaces, are produced on hyphae in the soil near the root surface. Type species:

A quick, accurate taxonomic identification of AMF isolates is necessary for culture collections (IBG, INVAM, SAF, CICG, and GINCO) and research and for industrial certification.

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.

Gigaspora sp (INVAM PA201) was isolated from a farm in Lancaster, PA. This fungus was grown on medium supplemented with 5 μm quercetin in the absence (left) and presence (right) of 2OH-TDA. A second type of bioassay was then used to accurately measure the concentration which could affect hyphal growth or hyphal branching.

The genus …

Some isolates in INVAM produce spores that are consistently white, but they tend to be 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 R. manihotis.Similar spores were also observed in ex-type pot cultures of A. delicata (W5747 of 14 Apr 2010 from INVAM AZ661, Att218-5, Fig. 1 C) and ex-epitype cultures of A. cavernata (W5738 of 20 Apr. 2010 from BEG33, Att209-66, Fig. 1 D).Several of these spores in a population from which DNA is extracted will introduce considerable contamination. On the bright side, these parasitized spores are easy to detect and remove. When we find a culture in this state, we go through at least two propagation cycles using only washed spores as inoculum.
