An endogenous rhythm of trap formation in the nematophagous fungus Arthrobotrys oligospora
Planta, 1981In the predacious fungus Arthrobotrys oligospora Fres., the number and distribution of traps formed after the addition of living nematodes to the colonies were determined. At 21°C the traps were formed periodically; the mean period was 42.3±0.8 h. The periodicity was independent of light-dark (LD) cycles of 24 h (10:14).

Effects of UV on the spores of the fungal species Arthrobotrys oligospora and A. ferox
Polar Biology, 2002The effects of UV irradiation (at λ>380 nm and λ>265 nm) on spore suspensions of a European strain of Arthrobotrys oligospora (hyphomycete) have been investigated and compared with those on a strain of the Antarctic species, A. ferox. Emission and excitation spectra of control and irradiated spore suspensions of both strains suggest a higher ...

Acta Parasitologica, 2021
Predatory fungi have been the subject of fundamental studies and their potential as biological control agents against parasitic plant nematodes has been assessed. The aim of the present study was to isolate and identify predatory fungi, performing in vitro and in vivo screening to select highly active strains to control parasitic nematodes.Different ...

Biological control of ruminant trichostrongylids by Arthrobotrys oligospora, a predacious fungus
Parasitology Today, 1989Sheep and cattle are prey to many parasitic worms, including the trichostrongylid nematodes. Conventional control involves the use of anthelmintic drugs, but in this article Hadji Ahmad Hashmi and Roger Connan discuss the possible biological control of these nematodes by means of a 'living lasso', the predacious fungus Arthrobotrys.

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.

A Nematotoxin produced by the Nematophagous Fungus Arthrobotrys oligospora Fresenius
Nature, 1963THE nematopagous fungus, Arthrobotrys oligospora Fres., captures nematodes by means of adhesive hyphal networks. When a nematode has been snared, the fungus pierces the animal's integument and produces a bulbous structure from which trophic hyphae grow throughout the body of the worm.

Ion Beam Mutagenesis in Arthrobotrys oligospora Enhances Nematode-Trapping Ability
Current Microbiology, 2013The nematode-trapping fungus Arthrobotrys oligospora is able to produce extracellular protease that degrades the body walls of parasitic nematode larvae found in livestock and immobilizes the nematodes. Our aim was to obtain a strain of A. oligospora with a strong ability to trap nematodes by production of high levels of extracellular protease.

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.

Adhesive hyphae ofArthrobotrys oligospora: an ultrastructural study
European Journal of Plant Pathology, 1996Electron microscopic studies of the interaction of second-stage juveniles ofMeloidogyne hapla andArthrobotrys oligospora (CBS 289.82) strongly suggest that hyphae attachment to nematodes was mediated by a 0.1μm thick layer matrix between the fungus and prey after contact with the nematode cuticle.

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.
