Abstract
Nematode-trapping fungi (NTF) and nematodes are common and sympatric in nature. The molecular basis that underlies this interkingdom predator-prey interaction remains largely uncharacterized. Both NTF and nematodes can be easily isolated from soil samples. NTF do not form traps in nutrient-rich environments, yet trap morphogenesis can be observed under nutrient-poor conditions and upon simultaneous sensing of the nematode cues. Here, we present protocols for laboratory maintenance and culturing of the model NTF Arthrobotrys oligospora.
