The genome sequence and gene predictions of Arthrobotrys oligospora were not determined by the JGI, but were downloaded from NCBI and have been. Therefore, we investigated the behavioral and molecular basis for how C. elegans responds to Arthrobotrys oligospora, one of the most. Of the 13 nematode-trapping fungi previously detected at the Bodega Marine Reserve (BMR, Sonoma County, CA, USA), Arthrobotrys oligospora is by far the.

For practical reasons we have decided not to translate all pages in several languages anymore because it was too heavy to maintain but some of the labels of the basic and advanced query pages are still available.

In permanent darkness, growth is somewhat less than in continuous light; vegetative extension is stimulated in the presence of nematodes A synthetic culture medium has been described ; the nematode-trapping activity is optimal in the range mg l-1 sucrose and mg NH4-nitrogen in a basal medium L-Arabinose and L-sorbose, Artbrobotrys, L-histidine, DL-tryptophan and urea are, however, utilized poorly oligosppra, Nitrite, nitrate and ammonium salts are suitable inorganic N sources Pectin, chitin and cellulose are utilized and the cellulases Cx and C1 have been shown to be present Saprophytic growth is very good on D-xylose, D-mannose, and cellobiose, but is further stimulated by the addition of biotin, thiamineCa-pantothenate, and p-amino benzoic acid, while D-ribose, L-rhamnose, lactose, D-mannitol, D-dulcitol, inulin, citrate, malate, glycine, and DL-lysine proved to be unsuitable substrates Proteolytic activity has been demonstrated Parasitized nematodes contain a substance that paralyses healthy nematodes; the presence of an unstable fungal toxin is assumed The oligospoa hyphal pigments have been analysed as?
Drechsler, DuddingtonHaardJarowajaJuniperand van Oorschot The nematode-trapping adhesive network has been illustrated by SEM It has been used in many ecological and physiological studies on predaceous fungi and has repeatedly been used in trials to assess its potential for the biological control of nematodes.
In studies on predaceous fungi it has been frequently recorded, for example, in the British Islesvarious parts of the USSR,PolandCanada IMINew Zealandand India ; it is known from forest-steppe soilsoils of a mixed forest IMIand a mediterranean brown soil of pH 6. Most reports of A. A marked increase in frequency has been observed in the rhizosphere of soya bean but in that of wheat the frequency was reduced and no isolates were obtained from washed root segments With citrus, on the other hand, its occurrence was found to be restricted to the rhizosphere There are also reports for the rhizospheres of barley, beans and sugar beet It has also been isolated from beech and pine wood baits buried in the surface layer of soils According to various reports, a frequently colonized habitat is partially decomposed plant material, leaves, roots, moss and dung,, ; it has also been isolated from larvae of the lovebug.
Plecia nearctica and cysts of the nematode Heterodera schachtii Growth in soil has been recorded between vapour saturation and bars water potential It has a relatively high competitive saprophytic ability compared to other nematode-trapping fungi with constricting rings but was found to be oligopsora to antagonistic influences by various soil organisms Its saprophytic existence in soil is enhanced by a capacity to degrade durable substrates such as cellulose The influence of the soil moisture level in remoistened air-dried soil on restoration of soil mycostasis was studied using A.
Its nematophagous activity in soil can be increased by adding green manure or carbohydrates The nematode content of a soil has occasionally been successfully reduced arthrobogrys the addition of A.
