Abstract

Products and byproducts of the metabolism of plant cell organelles can initiate reactions which result in radical formation. These highly active compounds are capable of emitting light or transferring excitation. If chlorophyll is present, it will probably receive excitation from the radicals and act as an emitter itself, resulting in apparently spontaneous light emission from dark-adapted plants. Spectral and kinetic data suggest that this phenomenon is different from fluorescence or delayed light emission. The aim of this work is to review new developments in the study of spontaneous ultraweak light emission from plant tissues, in particular recent evidence linking metabolic pathways to dark photoemission.
