Identification of chemical inhibitor of jasmonic acid advances study of plant signalling pathways [Registered]

Researchers at the Max Planck Institute for Plant Breeding Research in Cologne and University of Duisburg-Essen have identified a molecule that interferes with the effect of jasmonic acid. This plant hormone influences flower formation, root growth, defence against herbivores and infections, wound healing, ageing of plants, and much more. Although many questions about plant metabolism can be answered through targeted gene mutations, the method has its limits. This is also demonstrated in the case of jasmonic acid and its derivatives. So far, only one signalling chain has been discovered, but this cannot explain the wide-ranging effect of this plant hormone.…
