Purification and cloning of an extracellular serine protease from the nematode-trapping fungus Monacrosporium cystosporium.
An extracellular protease (Mc1) was isolated from the nematode-trapping fungus Monacrosporium cystosporium by gel filtration, anion-exchange, and hydrophobic interaction chromatographies. This protease had a molecular mass of approximately 38 kDa and displayed an optimal activity at pH 7-9 and 56 degrees (over 30 min). Its proteolytic activity was highly sensitive to the serine protease inhibit...
متن کاملEffects of the nematode-trapping fungus, Monacrosporium ellipsosporium on Meloidogyne incognita populations in field soil
Monacrosporium ellipsosporiwn was frequently observed associated with Meloidogyne egg masses in some field soils and in potted cultures of the nematode. Six geographic isolates varied in their relative predacity toward larvae emerging from egg masses. An aggressive isolate, chosen for rapidity and abundance of trap formation in vitro, was tested in greenhouse and field tests for protection of t...
متن کاملNematode-Trapping Fungi Eavesdrop on Nematode Pheromones
The recognition of molecular patterns associated with specific pathogens or food sources is fundamental to ecology and plays a major role in the evolution of predator-prey relationships. Recent studies showed that nematodes produce an evolutionarily highly conserved family of small molecules, the ascarosides, which serve essential functions in regulating nematode development and behavior. Here,...
متن کاملComparison of gene expression in trap cells and vegetative hyphae of the nematophagous fungus Monacrosporium haptotylum.
Nematode-trapping fungi enter the parasitic stage by developing specific morphological structures called traps. The global patterns of gene expression in traps and mycelium of the fungus Monacrosporium haptotylum were compared. The trap of this fungus is a unicellular spherical structure called the knob, which develops on the apex of a hyphal branch. RNA was isolated from knobs and mycelium and...
متن کاملNematode-Trapping in Pleurotus tuberregium
Pleurotus tuberregium is a common basidiomycete in parts of tropical Africa and Australia that fruits from a subterranean true sclerotium. Evidence from field collections suggests that the sclerotia are formed underground. Because its basidiocarps have intercalary skeletal hyphae, P. tuberregium has also been classified in both Lentinus and Panus. We investigated nematode-trapping in P. tuberre...
