Isolation, Identification, and Characterization of the Nematophagous Fungus Arthrobotrys oligospora from Kyrgyzstan

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 ...

The cAMP-PKA signaling pathway regulates hyphal growth, conidiation, trap morphogenesis, stress tolerance, and autophagy in Arthrobotrys oligospora.

Environmental Microbiology, 2022
The cyclic adenosine monophosphate-protein kinase A (cAMP-PKA) signaling pathway is evolutionarily conserved in eukaryotes and plays a crucial role in defending against external environmental challenges, which can modulate the cellular response to ...

Protoplast formation from adhesive network traps of Arthrobotrys oligospora

Mycological Research, 1989
The selective formation of protoplasts from nematode-trapping structures of Arthrobotrys oligospora was achieved by taking advantage of the differential susceptibility to enzymic digestion of trap-cell walls and that of older hyphae. Trap protoplasts were obtained after treatment of cultures, grown on dialysis membranes, with a Trichoderma enzyme ...

Transcription Levels of SDR Gene Ao274 in Nematode-Trapping Fungus Arthrobotrys oligospora Regulates Configurations and Oxidation Patterns of Arthrobotrisins and Formation of Trapping Devices.

Journal of Agricultural and Food Chemistry
Here, we report hierarchical functions of a putative short-chain dehydrogenase/reductase gene Ao274 for arthrobotrisin biosynthesis in nematode-trapping fungus Arthrobotrys oligospora via an enhanced promoter. Transcriptional analysis revealed that Ao274

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.

Suppression of root‐knot nematode Meloidogyne incognita on tomato plants using the nematode trapping fungus Arthrobotrys oligospora Fresenius

Journal of Applied Microbiology, 2021
The aims of the study were to isolate and characterize the nematode trapping fungus, Arthrobotrys oligospora, to investigate the suppressive and predacious activities of the fungus against Meloidogyne incognita and to study the potentiality of A ...

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.

Arthrobotrys oligospora (Fungi: Orbiliales) and its liquid culture filtrate myco-constituents kill Haemonchus contortus infective larvae (Nematoda: trichostrongylidae)

Biocontrol science and technology (Print)
Arthrobotrys oligospora is a nematode-trapping fungus belonging to the family Orbiliaceae and one of the main antagonists of nematodes in soil, including plant and animal parasitic nematodes and free-living nematodes.

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.

Rare NRPS Gene Cluster for Desferriferrichrome Biosynthesis Controls the Conflict between Trap Formation and Nematicidal Activity in Arthrobotrys oligospora.

Journal of Agricultural and Food Chemistry
The formation of the trapping device induced by nematodes has been assumed as an indicator for a switch from saprophytic to predacious lifestyles for nematode-trapping fungi.
