Nematode-trapping fungi eavesdrop on nematode pheromones. [PDF]

Curr Biol, 2013
The recognition of molecular patterns associated with specific pathogens or food sources is fundamental to ecology and plays a major role in the evolution of predator-prey relationships. Recent studies showed that nematodes produce an evolutionarily highly conserved family of small molecules, the ascarosides, which serve essential functions in ...

Bacteria can mobilize nematode-trapping fungi to kill nematodes. [PDF]

Nat Commun, 2014
AbstractIn their natural habitat, bacteria are consumed by bacterivorous nematodes; however, they are not simply passive preys. Here we report a defensive mechanism used by certain bacteria to mobilize nematode-trapping fungi to kill nematodes. These bacteria release urea, which triggers a lifestyle switch in the fungus Arthrobotrys oligospora from ...

Sampling methods affect Nematode-Trapping Fungi biodiversity patterns across an elevational gradient. [PDF]

BMC Microbiol, 2020
Abstract Background Understanding the patterns of species richness across elevational gradients is a key concept for contemporary research in ecology and evolution, and critical to understanding large-scale trends in biodiversity, global change and conservation. However, patterns of elevational species richness between taxonomic groups, regions

Roles of the Fungal-Specific Lysine Biosynthetic Pathway in the Nematode-Trapping Fungus Arthrobotrys oligospora Identified through Metabolomics Analyses

Journal of Fungi, 2023
In higher fungi, lysine is biosynthesized via the α-aminoadipate (AAA) pathway, which differs from plants, bacteria, and lower fungi. The differences offer a unique opportunity to develop a molecular regulatory strategy for the biological control of ...

New Arthrobotrys Nematode-Trapping Species (Orbiliaceae) from Terrestrial Soils and Freshwater Sediments in China

Journal of Fungi, 2022
Arthrobotrys is the most complex genus of Orbiliaceae nematode-trapping fungi. Its members are widely distributed in various habitats worldwide due to their unique nematode-trapping survival strategies.

Ultrastructure of Nematode-Trapping Fungi [PDF]

Journal of Bacteriology, 1972
Capture cells differ ultrastructurally from vegetative cells in the nematode-trapping fungi, Dactylella drechslerii, Monacrosporium rutgeriensis and Arthrobotrys dactyloides , which capture prey by means of adhesive knobs, adhesive hyphal networks, and constricting rings, respectively ...

Collagenase Production by Nematode-Trapping Fungi [PDF]

Applied and Environmental Microbiology, 1980
A number of species of nematode-trapping fungi, which capture and digest nematodes having keratin and collagen in their cuticles, were tested for the ability to produce extracellular collagenase and keratinase. Collagenase, which is active on ichthyocol, earthworm collagen, and procollagen from chicken embryo fibroblasts, was found in the ...

High Predatory Capacity of a Novel Arthrobotrys oligospora Variety on the Ovine Gastrointestinal Nematode Haemonchus contortus (Rhabditomorpha: Trichostrongylidae)

Pathogens, 2021
With the worldwide development of anthelmintic resistance, new alternative approaches for controlling gastrointestinal nematodes in sheep are urgently required. In this work, we identified and characterized native nematode-trapping fungi.

Inactivation of the Burkholderia Toxin Malleicyprol by Enzymatic Cyclopropanol Ring Opening. [PDF]

Angew Chem Int Ed Engl
Burkholderia pseudomallei and Burkholderia mallei are dangerous pathogens that cause severe diseases with high mortality rates. Their virulence relies in part on malleicyprols, potent toxins containing a highly reactive cyclopropanol group. In this study, we identify BurK, a heme‐dependent oxidoreductase that neutralizes malleicyprols by enzymatically ...

Identification of Three Novel Conidiogenesis-Related Genes in the Nematode-Trapping Fungus Arthrobotrys oligospora

Pathogens, 2022
For filamentous fungi, conidiogenesis is the most common reproductive strategy for environmental dispersal, invasion, and proliferation. Understanding the molecular mechanisms controlling conidiation and increasing conidium yield may provide promising ...
