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.

Ammonia and Nematode Ascaroside Are Synergistic in Trap Formation in Arthrobotrys oligospora. [PDF]

Pathogens, 2023
Nematode-trapping (NT) fungi are natural predators of the soil living nematodes. Diverse external signals mediate the generation of predatory devices of NT fungi. Among these, broad ascarosides and nitrogenous ammonia are highly efficient inducers for trap structure initiation.

AoMedA has a complex regulatory relationship with AoBrlA, AoAbaA, and AoWetA in conidiation, trap formation, and secondary metabolism in the nematode-trapping fungus Arthrobotrys oligospora. [PDF]

Appl Environ Microbiol, 2023
The asexual sporulation of filamentous fungi is an important mechanism for their reproduction, survival, and pathogenicity. In Aspergillus and several filamentous fungi, BrlA, AbaA, and WetA are the key elements of a central regulatory pathway ...

Biological Characteristics of Recombinant Arthrobotrys oligospora Chitinase AO-801. [PDF]

Korean J Parasitol, 2022
Chitinase AO-801 is a hydrolase secreted by <i>Arthrobotrys oligospora</i> during nematode feeding, while its role remained elusive. This study analyzed the molecular characteristics of recombinant chitinase of <i>Arthrobotrys oligospora</i> (reAO-801).

Proteomic insights into nematode-trapping fungi <i>Arthrobotrys oligospora</i> after their response to chitin. [PDF]

J Vet Res
Introduction Nematode-trapping fungi (NTFs) can produce various chitinases to degrade nematode body wall and eggshell chitin during predation. However, the regulatory mechanisms of their expression of chitinases still remain unclear.

Predatory activity and nematocidal compounds released into liquid culture filtrates as attack strategies of a Mexican strain of Arthrobotrys oligospora against Haemonchus contortus infective larvae. [PDF]

PLoS ONE
Nematophagous fungi offer a sustainable alternative for controlling nematode infections in small ruminants. The aims were to isolate and characterize both morphological and molecular nematophagous fungi from soil, to assess their predatory activity and ...

Function discovery of a non-ribosomal peptide synthetase-like encoding gene in the nematode-trapping fungus Arthrobotrys oligospora [PDF]

Frontiers in Microbiology, 2023
In this study, the function of a non-ribosomal peptide synthetase-like (NRPS-like) encoding gene AOL_s00188g306 (g306) was investigated to reveal the association between NRPS and nematocidal activity in the nematode-trapping fungus Arthrobotrys ...
