Nematophagous fungi: physiological aspects and structure-function relationships.
Publisher Summary The chapter discusses physiological, biochemical, and ultrastructural aspects of both predatory and endoparasitic nematophagous fungi and explains current views on the role of the
Action of a nematode-trapping fungus shows lectin-mediated host–microorganism interaction
The hypothesis is that the firmness of attachment to the traps despite the struggle of the nematode is due to a series of events, beginning with an interaction between complementary molecular configurations on the nem atode and fungal surfaces.
Significance of electron dense microbodies in trap cells of the nematophagous fungus Arthrobotrys oligospora
The present results support the current view that traps of A. oligospora contribute to the survival of the organism in its natural environment.
Development and fate of electron-dense microbodies in trap cells of the nematophagous fungusArthrobotrys oligospora
The development of electron-dense microbodies in cells of capture organs of the nematophagous fungus Arthrobotrys oligospora was studied with different ultrastructural techniques and suggested that their presence must be explained by dilution of organelles in newly formed cells.
Fungal parasitism of the cyst nematode Heterodera schachtii: infection and enzymatic activity
The ability of the fungi to infect eggs was correlated with their lytic enzyme activity, and fungi that readily infected eggs also showed chitinase activity and presence of proteolytic activity.
Morphogenesis in the nematode-trapping fungus Arthrobotrys oligospora - an extensive plasticity of infection structures
The application of genomics to understand the function and the development of infection structures, therefore, has substantially increased the potential of A. oligospora to become a model system for fungal morphogenesis.
Dialysis Membrane Technique for Studying Microbial Interaction
A dialysis membrane method is described which allows (i) cultivation of fungi on an agar support, (ii) observation of growth and development by direct light microscopy, (iii) transfer of cultures
An electron-microscopical analysis of capture and initial stages of penetration of nematodes byArthrobotrys oligospora
A detailed analysis was made of the capture and subsequent penetration of nematodes by the nematophagous fungusArthrobotrys oligospora using different electron-microscopical techniques. Capture of
The Influence of Medium Composition and Additions of Animal Origin on the Formation of Capture Organs in Arthrobotrys oligospora
The formation of capture organs for nematodes in A. oligospora was studied in laboratory experiments and it was found that the initialing factor is, for full effect, bound to the living state and not confined to nematode.
Occurrence and metabolic significance of microbodies in trophic hyphae of the nematophagous fungus Arthrobotrys oligospora
The results suggest that part of the nutrients released from the nematode are first converted into lipids by the fungus which in turn are degraded via the β-oxidation pathway and further metabolized to support growth of new vegetative hyphae.
