Abstract:
Lipoxygenase (LOX) and peroxidase (POD) reactions, which are involved in the production of reactive oxygen and radical species, are shown to be associated with ultraweak photon emission in plant defense mechanisms. These enzyme reactions induced high-level ultraweak photon emission in an in vitro reaction system. The application of LOX to sweet potato slices caused photon emission directly in plants. LOX substrate promoted photon emission in chitosan-treated sweet potato, and LOX inhibitor markedly suppressed this emission. Therefore, a LOX-related pathway, including LOX and other downstream reactions, is principally associated with photon emission in plant defense mechanisms.
