Keratitis due toArthrobotrys oligosporaFres. 1850

Medical Mycology, 1990
Mycotic keratitis caused by Arthrobotrys oligospora is reported in a 62-year-old Indian male patient. The diagnosis was made by direct microscopic examination, isolation of large quantities of the fungus on multiple media and the response of the lesion to an antifungal compound.

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 ...

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).

Cellular communication and fusion regulate cell fusion, trap morphogenesis, conidiation, and secondary metabolism in Arthrobotrys oligospora.

Microbiology Research, 2023
Signal-mediated cell fusion is vital for colony development in filamentous fungi. Arthrobotrys oligospora is a representative nematode-trapping (NT) fungus that produces adhesive networks (traps) to capture nematodes. Here, we characterized Aoadv-1, Aoso,

Effects of UV on the spores of the fungal species Arthrobotrys oligospora and A. ferox

Polar Biology, 2002
The 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 ...

AoRab7A interacts with AoVps35 and AoVps41 to regulate vacuole assembly, trap formation, conidiation, and functions of proteasomes and ribosomes in Arthrobotrys oligospora.

Microbiology Research, 2023
Rab GTPases regulate vesicle trafficking in organisms and play crucial roles in growth and development. Arthrobotrys oligospora is a ubiquitous nematode-trapping (NT) fungus, it can form elaborate traps to capture nematodes. Our previous study found that

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.

The lifestyle transition of Arthrobotrys oligospora is mediated by microRNA-like RNAs

Science China Life Sciences, 2019
The 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.

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

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 ...
