Molecular characterization of an expressed sequence tag representing the cuticle-degrading serine protease gene (PII) from the nematophagous fungus Arthrobotrys oviformis by differential display technology.
The technology of mRNA-based differential display reverse transcriptase-polymerase chain reaction (DDRT-PCR) was used to detect a 246-bp differentially expressed fragment from the nematophagous fungus Arthrobotrys oviformis when young mycelia were induced with the round worm Haemonchus contortus. The fragment was converted into an expressed sequence tag (EST) through characterization at the mol...
متن کاملNematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey
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. Gas-chromatographic mass-spectral analyses of A. oligospora-derived volatile metabolites identified several odors mimicking food cues attract...
متن کاملSurface polymers of the nematode-trapping fungus Arthrobotrys oligospora.
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. Both traps and hyphae were surrounded by a fibrillar layer of ...
متن کاملGenetic diversity and recombination in natural populations of the nematode-trapping fungus Arthrobotrys oligospora from China
Nematophagous fungi can trap and capture nematodes and other small invertebrates. This unique ability has made them ideal organisms from which to develop biological control agents against plant- and animal-parasitic nematodes. However, effective application of biocontrol agents in the field requires a comprehensive understanding about the ecology and population genetics of the nematophagous fun...
متن کاملSpecific induction of a cuticle-degrading protease of the insect pathogenic fungus Metarhiziurn anisopliae
The insect pathogenic fungus Metarhizium anisopliae produces several extracellular cuticle-degrading proteases and evidence is consistent that one of these, a chymoelastase PRl, is a determinant of pathogenicity. We have shown previously that the wide-domain regulatory circuits of carbon and nitrogen derepression regulate PRI production. In the present work we have established in addition that ...
