This laboratory study on the nematode-trapping fungus Arthrobotrys oligospora found that ammonia and a specific nematode chemical (Ascr#18) work together synergistically to induce the formation of predatory traps more effectively than either signal alone.
This preclinical study investigated how two external signals, ammonia and ascarosides, affect the formation of predatory traps in the nematode-trapping fungus *Arthrobotrys oligospora*. Using a laboratory-based experimental design, the researchers demonstrated that combining ammonia with the nematode-derived ascaroside Ascr#18 resulted in a significantly higher production of adhesive net traps compared to each inducer used individually. The study further explored the mechanism, showing that the ammonia transceptor Amt43 is required for trap formation in response to ammonia but not to Ascr#18. Additionally, ammonia was found to promote plasma membrane endocytosis during trap formation, while Ascr#18 addition appeared to stabilize intracellular organization. The work suggests that these synergistic signals may help the fungus adapt to complex soil environments.
