Carotenoid pigments of the nematode-trapping hyphomycete Arthrobotrys oligospora (fres.)
Phytochemistry, 1963Abstract Arthrobotrys oligospora was found to contain β- and γ-carotene, neurosporoxanthin and torulene; β-carotene being the most abundant and the other three pigments fairly equal in distribution. It is suggested that the pigment characteristics of the fungi in the nematophagous series may be an aid in elucidating their taxonomic affinities.

Hyphal fusion during initial stages of trap formation in Arthrobotrys oligospora
Antonie van Leeuwenhoek, 1989Hyphal fusion during initial stages of trap formation by Arthrobotrys oligospora was studied by video-enhanced contrast and electron microscopy. Trap initials grew perpendicularly to the parent hypha, then curved around and anastomosed with a peg that developed on the hypha.

Transfer of phosphorus from Rhizoctonia solani to the mycoparasite Arthrobotrys oligospora
Mycological Research, 1994Arthrobotrys oligospora parasitizes Rhizoctonia solani by coiling around the host hyphae and killing the cells under the coils and adjacent cells without penetrating the host cell wall. In experiments with one isolate of A. oligospora and one isolate of R. solani phosphorus was transferred from R. solani to A.

Wood, nematodes, and the nematode-trapping fungus Arthrobotrys oligospora
Soil Biology and Biochemistry, 2004Abstract Researchers have proposed that Arthrobotrys oligospora and related fungi trap soil nematodes to obtain nitrogen and thereby compete saprophytically for carbon and energy in nitrogen-poor environments, including litter and wood. The current study tested two hypotheses concerning this model.

The nematophagous fungus Arthrobotrys oligospora Fres. can live saprophytically as well as predatorily. As a predator it forms sticky reticulate traps in the presence of living nematodes which enable it to kill and consume the animals. In laboratory experiments the nutrient acquisition of the fungus was tested on agar media with various N- and C ...

Nematode-Induced Morphogenesis in the Predacious Fungus Arthrobotrys Oligospora
Nematologica, 1977Living nematodes induced trap formation in Arthrobotrys oligospora more rapidly than did additions of morphogenetic peptides. In nematode-induced morphogenesis, excreted substances as peptides and amino acids were only partly responsible for the effect.

Soil fungistasis limits the effect of fungal agents designed to control plant-parasitic nematodes. Benzaldehyde is a fungistatic factor produced by soil microorganisms that can suppress conidial germination, but the molecular mechanism of this suppression is unknown.

Protoplast formation from adhesive network traps of Arthrobotrys oligospora
Mycological Research, 1989The selective formation of protoplasts from nematode-trapping structures of Arthrobotrys oligospora was achieved by taking advantage of the differential susceptibility to enzymic digestion of trap-cell walls and that of older hyphae. Trap protoplasts were obtained after treatment of cultures, grown on dialysis membranes, with a Trichoderma enzyme ...

Scanning Electron Microscopy of the Nematode‐trapping Organs in Arthrobotrys oligospora
Physiologia Plantarum, 1972AbstractThe three‐dimensional capture organs of the nematodetrapping fungus Arthrobotrys oligospora are presented in scanning electron micrographs.The fungus was grown directly on agar substrates or on millipore filters or glass cover slips placed on agar substrates. To avoid shrinkage of the soft‐walled mycelial material, a fixation in OsO4‐vapour was

The influence of fungicides on Arthrobotrys oligospora in simulated putting green soil
Annals of Applied Biology, 2005Summary Plant-parasitic nematodes are destructive pests in bentgrass putting greens. Few chemical or nonchemical approaches for nematode management exist. Studies were conducted to determine: the in vitro tolerance of the nematophagous fungus Arthrobotrys oligospora, to the fungicides chlorothalonil and myclobutanil used to manage diseases on putting ...
