Environmental stresses often cause serious damages to plants, and many cases of environmental stresses are accompanied by oxidative stress derived from overproduced reactive oxygen species (ROS). In chloroplasts under oxidative stress, stimulated peroxidation of polyunsaturated fatty acids by ROS generates reactive carbonyls that can act as toxic and signaling chemicals, RSLVs (Reactive Short-chain Leaf Volatiles). In this note, mechanism of production of reactive carbonyls and their physiological roles in environmental stress response are discussed.
