Adhesive hyphae ofArthrobotrys oligospora: an ultrastructural study

European Journal of Plant Pathology, 1996
Electron 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.

Biological control of ruminant trichostrongylids by Arthrobotrys oligospora, a predacious fungus

Parasitology Today, 1989
Sheep 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.

Hyphal fusion during initial stages of trap formation in Arthrobotrys oligospora

Antonie van Leeuwenhoek, 1989
Hyphal fusion during initial stages of trap formation by Arthrobotrys oligospora was studied by video-enhanced contrast and electron microscopy. Trap initials grew perpendicularly to the parent hypha, then curved around and anastomosed with a peg that developed on the hypha.

Wood, nematodes, and the nematode-trapping fungus Arthrobotrys oligospora

Soil Biology and Biochemistry, 2004
Abstract Researchers have proposed that Arthrobotrys oligospora and related fungi trap soil nematodes to obtain nitrogen and thereby compete saprophytically for carbon and energy in nitrogen-poor environments, including litter and wood. The current study tested two hypotheses concerning this model.

Arthrobotrisins A–C, Oligosporons from the Nematode-Trapping Fungus Arthrobotrys oligospora

Journal of Natural Products, 2011
Arthrobotrys oligospora is a carnivorous fungus that can use mycelia trapping devices to capture their prey. Three novel oligosporons, named arthrobotrisins A-C (1-3), were isolated from A. oligospora and identified by spectroscopic analysis in combination with X-ray diffraction.

A Nematotoxin produced by the Nematophagous Fungus Arthrobotrys oligospora Fresenius

Nature, 1963
THE 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.

Nematode-Induced Morphogenesis in the Predacious Fungus Arthrobotrys Oligospora

Nematologica, 1977
Living nematodes induced trap formation in Arthrobotrys oligospora more rapidly than did additions of morphogenetic peptides. In nematode-induced morphogenesis, excreted substances as peptides and amino acids were only partly responsible for the effect.

Carotenoid pigments of the nematode-trapping hyphomycete Arthrobotrys oligospora (fres.)

Phytochemistry, 1963
Abstract Arthrobotrys oligospora was found to contain β- and γ-carotene, neurosporoxanthin and torulene; β-carotene being the most abundant and the other three pigments fairly equal in distribution. It is suggested that the pigment characteristics of the fungi in the nematophagous series may be an aid in elucidating their taxonomic affinities.

An endogenous rhythm of trap formation in the nematophagous fungus Arthrobotrys oligospora

Planta, 1981
In 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).

Proteomic changes in Arthrobotrys oligospora conidia in response to benzaldehyde-induced fungistatic stress

Journal of Proteomics, 2019
Soil fungistasis limits the effect of fungal agents designed to control plant-parasitic nematodes. Benzaldehyde is a fungistatic factor produced by soil microorganisms that can suppress conidial germination, but the molecular mechanism of this suppression is unknown.
