Screening of Soil and Sheep Faecal Samples for Predacious Fungi: Isolation and Characterization of the Nematode-Trapping Fungus Arthrobotrys oligospora
Over one-year period, 150 pasture soil samples and 138 sheep faecal samples, collected from different parts of Iran were screened for the presence of nematophagous fungi. The samples were cultured at 25ºC on chloramphenicol-2% water agar (CHF-WA) plates in the presence of Haemonchus contortus third stage larvae (L3) and checked over a two-month period for characteristic conidia, conidiophores a...
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 کاملEvolution of parasitism in nematode-trapping fungi.
We are studying the evolution of parasitism in a group of soil-living ascomycetes that can grow as saprophytes as well as parasites by forming special morphological structures called traps. Analyses of 18S ribosomal DNA sequences have shown that these fungi form a monophyletic and isolated clade among the ascomycetes. The phylogenetic patterns within this clade are concordant with the morpholog...
متن کاملSoil Fungi-Plant Interaction
One of the main European agricultural problems is the decline in soil fertility due to the reduction of the natural soil harmony. When natural soil composition is altered, few cultivated plants replace spontaneous populations of numerous species. Man becomes the only regulator of a new fragile equilibrium between the simplified biocenosis elements. Agronomic techniques (fertilisation, irrigatio...
