Jasmonates are important regulators in plant responses to biotic and abiotic stresses as well as in development. In ordinary plants, jasmonic acid and its derivates accumulate after pathogen or herbivore attack triggering a defense response and their accumulation is strongly associated with generation and propagation of electrical signals. In the carnivorous plants within the order Caryophyllales, jasmonic acid accumulates in response to mechanical and chemical stimuli from insect prey and triggers expression and secretion of digestive enzymes. Thus, the carnivorous plants co-opted the well-known plant defense hormone jasmonic acid for regulation of digestive enzyme activity. But carnivorous plants have at least eleven independent origins, and not all co-opted jasmonate signaling for botanical carnivory. Although different evolutionary lineages of carnivorous plants use similar digestive enzymes, the mode of their regulation strongly differs.
