摘要

Living organisms spontaneously emit faint light, and this autoluminescence is stimulated in response to many stresses. This phenomenon is attributable to the endogenous production of excited states during oxidative reactions, particularly during peroxidation of lipids, which generates light-emitting molecules such as triplet carbonyls and singlet oxygen. Using highly sensitive cameras, it is now possible to remotely image spontaneous luminescence with a good spatial resolution, providing a new non-invasive tool for mapping oxidative stress and lipid peroxidation in plants.
