Nematode-Trapping Fungi in Organic and Conventional Cropping Systems [PDF]

Phytopathology®, 1998
Nematode-trapping fungi, nematodes, and microbial biomass were quantified in conventionally and organically managed field plots in the Sustainable Agriculture Farming Systems Project at the University of California at Davis. There were four replicate plots (0.135 ha per plot) for each management system, and plots were sampled three times each year for

Peroxin Pex14/17 Is Required for Trap Formation, and Plays Pleiotropic Roles in Mycelial Development, Stress Response, and Secondary Metabolism in Arthrobotrys oligospora

mSphere, 2023
The peroxins encoded by PEX genes involved in peroxisome biogenesis play a crucial role in cellular metabolism and pathogenicity in fungi. Herein, we characterized a filamentous fungus-specific peroxin Pex14/17 in the Arthrobotrys oligospora, a ...

Nematode-Trapping Fungi in Biological Control of Dictyocaulus viviparus [PDF]

Acta Veterinaria Scandinavica, 1997
Larvae of the cattle lungworm Dictyocaulus viviparus were cultured in experimental units of 200 g cattle faeces placed in semi-transparent trays in the laboratory. In each of 4 experimental series using this experimental unit, chlamydospores (chl) of the nematode-trapping fungus Duddingtonia flagrans were admixed to half of the faecal cultures in a ...

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 ...

Arthrobotrys blastospora sp. nov. (Orbiliomycetes): A Living Fossil Displaying Morphological Traits of Mesozoic Carnivorous Fungi

Journal of Fungi, 2023
The evolution of carnivorous fungi in deep time is still poorly understood as their fossil record is scarce. The approximately 100-million-year-old Cretaceous Palaeoanellus dimorphus is the earliest fossil of carnivorous fungi ever discovered.

Phylogeny of nematode-trapping fungi based on 18S rDNA sequences [PDF]

FEMS Microbiology Letters, 1998
The small subunit (SSU) ribosomal DNA (18S rDNA) from 15 species of nematode-trapping fungi and closely related non-parasitic species were sequenced. Phylogenetic analysis indicated that species within the genera of Arthrobotrys, Dactylaria, Dactylella, Monacrosporium and Duddingtonia formed a monophyletic and isolated clade among an unresolved cluster

Use of Arthrobotrys spp. in biocontrol of the root-knot nematode Meloidogyne incognita

European Journal of Biological Research, 2023
Plant parasitic nematodes are well-known and devastating pathogens of many agricultural crops around the world. Among the plant phytoparasitic, root-knot nematodes (Meloidogyne spp.) are the economically important limiting factors in agricultural ...

Genomic and proteomic analyses of the fungus Arthrobotrys oligospora provide insights into nematode-trap formation.

PLoS Pathogens, 2011
Nematode-trapping fungi are "carnivorous" and attack their hosts using specialized trapping devices. The morphological development of these traps is the key indicator of their switch from saprophytic to predacious lifestyles.

Effect of Nematode Population Densities on Trapping Activity of Nematophagous Fungus Arthrobotrys Dactyloides on Meloidogyne Javanica [PDF]

, 2011
Trapping activities of some nematophagous fungi were suggested to be related to the population density of nematodes. This study determined the trapping activity of Arthrobotrys dactyloides due to the effects of (i) different populations of Meloidogyne ...

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.
