AoMbp1 Governs Conidiation and Trap Morphogenesis in Arthrobotrys oligospora Via Direct Transcriptional Activation of the MAPK Sensor AoSho1 [PDF]

Journal of Fungi
The nematode-trapping fungus (NTF) Arthrobotrys oligospora (A. oligospora) is a promising biocontrol agent, but the transcriptional regulators governing its predation remain poorly understood.

DNA methylation plays important roles in lifestyle transition of Arthrobotrys oligospora. [PDF]

IET Syst Biol
Abstract Trap formation is the key indicator of carnivorous lifestyle transition of nematode‐trapping fungi (NTF). Here, the DNA methylation profile was explored during trap induction of Arthrobotrys oligospora , a typical NTF that captures nematodes by developing adhesive ...

Historical Differentiation and Recent Hybridization in Natural Populations of the Nematode-Trapping Fungus Arthrobotrys oligospora in China [PDF]

Microorganisms, 2021
Maintaining the effects of nematode-trapping fungi (NTF) agents in order to control plant-parasitic nematodes (PPNs) in different ecological environments has been a major challenge in biological control applications.

AoRan1 Is Involved in Regulating Conidiation, Stress Resistance, Secondary Metabolism, and Pathogenicity in Arthrobotrys oligospora [PDF]

Microorganisms
Arthrobotrys oligospora is a representative nematode-trapping (NT) fungus that is able to capture, kill, and digest nematodes by producing specialized three-dimensional networks (traps) under nutrient-deprived conditions.

Surface polymers of the nematode-trapping fungus Arthrobotrys oligospora [PDF]

Journal of General Microbiology, 1991
The nematophagous fungus Arthrobotrys oligospora captures nematodes using adhesive polymers present on special hyphae (traps) which form a three-dimensional network. To understand further the adhesion mechanisms, A. oligospora surface polymers were visualized by transmission electron microscopy and characterized by chemical methods.

Laboratory Maintenance and Culturing of the Nematode‐Trapping Fungus Arthrobotrys oligospora

Current Protocols, 2021
AbstractNematode‐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.

Pleiotropic roles of Ras GTPases in the nematode-trapping fungus Arthrobotrys oligospora identified through multi-omics analyses

iScience, 2021
Summary: The nematode-trapping fungi are ideal agents for controlling pathogenic nematodes. Arthrobotrys oligospora is a representative species of the same, producing traps for nematode predation. Here, three orthologous Ras GTPases (Ras2, Ras3, and Rheb)

Transformation of the nematode-trapping fungusArthrobotrys oligospora [PDF]

FEMS Microbiology Letters, 1999
The nematode-trapping fungus Arthrobotrys oligospora was transformed to hygromycin resistance using the hygromycin-B phosphotransferase gene from Escherichia coli under the control of various heterologous fungal promoters. Plasmid DNA was introduced into fungal protoplasts by polyethylene glycol/CaCl2 treatment.

The High Osmolarity Glycerol (HOG) Pathway Functions in Osmosensing, Trap Morphogenesis and Conidiation of the Nematode-Trapping Fungus Arthrobotrys oligospora

Journal of Fungi, 2020
Hog1, a mitogen-activated protein kinase (MAPK), has been identified in diverse fungal species, and it regulates various cellular processes, such as osmoadaptation, nutrient-sensing, and pathogenesis.

Nematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey [PDF]

eLife, 2017
To study the molecular basis for predator-prey coevolution, we investigated how Caenorhabditis elegans responds to the predatory fungus Arthrobotrys oligospora. C. elegans and other nematodes were attracted to volatile compounds produced by A. oligospora.
