Opakovaná mechanická stimulace spouštěcích výčnělků, které vystupují z pokožky uvnitř pasti mucholapky podivné (Dionaea muscipula), vyvolává elektrické signály a spouští jasmonátovou signalizaci a expresi genů trávicích enzymů, příbuzných s proteiny vyvolanými patogenezí (PR proteiny). Tento sled událostí připomíná dobře známou signální dráhu obrany rostlin v odpovědi na útok patogenu nebo býložravce. Jak ale tedy mucholapka pozná, že jde skutečně o živočišnou kořist?

Repeated mechanical stimulation of trigger hairs protruding from the upper trap epidermis in the carnivorous Venus Flytrap (Dionaea muscipula) generates electrical signals and triggers jasmonate signalling and gene expression of digestive enzymes which are related to pathogenesis-related proteins (PR proteins). This sequence of events resembles the well-known plant defence signalling pathway in response to pathogen or herbivore attack. But how does the Venus Flytrap know that there is really an animal prey in its trap?
