Transfer of phosphorus from Rhizoctonia solani to the mycoparasite Arthrobotrys oligospora
Mycological Research, 1994Arthrobotrys oligospora parasitizes Rhizoctonia solani by coiling around the host hyphae and killing the cells under the coils and adjacent cells without penetrating the host cell wall. In experiments with one isolate of A. oligospora and one isolate of R. solani phosphorus was transferred from R. solani to A.

Scanning Electron Microscopy of the Nematode‐trapping Organs in Arthrobotrys oligospora
Physiologia Plantarum, 1972AbstractThe three‐dimensional capture organs of the nematodetrapping fungus Arthrobotrys oligospora are presented in scanning electron micrographs.The fungus was grown directly on agar substrates or on millipore filters or glass cover slips placed on agar substrates. To avoid shrinkage of the soft‐walled mycelial material, a fixation in OsO4‐vapour was

Nutritional Requirements and Mass Production of Nematode-trapping Fungus, Arthrobotrys oligospora
Journal of Asia-Pacific Entomology, 2004Abstract Various carbon and nitrogen sources were evaluated to develop an inexpensive medium for the mass production of nematode-trapping fungus, Arthrobotrys oligospora. A. oligospora utilized a wide range of carbon and nitrogen sources. Liquid fermentation system containing sucrose and yeast extract in the ratio of 5:1 was proposed.

The lifestyle transition of Arthrobotrys oligospora is mediated by microRNA-like RNAs
Science China Life Sciences, 2019The lifestyle transition of fungi, defined as switching from taking organic material as nutrients to pathogens, is a fundamental phenomenon in nature. However, the mechanisms of such transition remain largely unknown. Here we show microRNA-like RNAs (milRNAs) play a key role in fungal lifestyle transition for the first time.

Influence of phosphate on development of the nematode-trapping fungus Arthrobotrys oligospora
Microbiological Research, 1996Arthrobotrys oligospora captures and digests nematodes by means of adhesive networks. These traps are formed in the presence of nematodes but can also be induced by low nutrient media containing amino acids. Influence of phosphate on growth and development of A.

Extracellular proteases, such as chitinases secreted by Arthrobotrys oligospora (A. oligospora), play a crucial role in the process of nematode infection. However, post-transcriptional regulation of gene expression involving microRNAs (miRNAs) in A. oligospora remains scarcely described.

Laboratory Maintenance and Culturing of the Nematode-Trapping Fungus Arthrobotrys oligospora
2021Nematode-trapping fungi (NTF) and nematodes are common and sympatric in nature. The molecular basis that underlies this interkingdom predator-prey interaction remains largely uncharacterized. Both NTF and nematodes can be easily isolated from soil samples. NTF do not form traps in nutrient-rich environments, yet trap morphogenesis can be observed under

X-ray microanalysis of the nematode-trapping organs in Arthrobotrys oligospora
Transactions of the British Mycological Society, 1977Normal hyphae and nematode traps of Arthrobotrys oligospora Fres. were investigated by X-ray microanalysis and scanning electron microscopy. These morphogenetically dissimilar structures differed in the distribution of elements of low atomic number, the traps always showing a higher potassium content than hyphae, indicating higher metabolic activity ...

Hodnocení růstových a produkčních parametrů nematofágní houby Arthrobotrys oligospora
2010This M.Sc. thesis is aimed to describe growth and production parameters of nematophagous fungus Arthrobotrys oligospora. There was determinated information about growth and sporulation of fungus on artificial and natural substrates, influence of cultivation condition on production biomass and possibility of formulation alginate pellets.
