Chemical and constitutive priming share a common metabolomic fingerprint


Abstract: Plants defense responses are mediated by a wide variety of metabolic pathways, understanding which one is effective to counterattack the infection is our interest. Priming is a particular defense mechanism of the plant that can be induced by different signaling pathways. In the present study we aim to compare between priming chemically induced or acquired constitutively due to a mutation. To find a common profile of active metabolites in priming the plant defenses against the necrotrophic pathogen Plectosphaerella cucumerina an accurate mass detection tool HPLC coupled by time-of-flight detector was employed.
