Oxidation of lipids generates large quantities of highly reactive alpha,beta-unsaturated aldehydes (enals). Enals and their protein adducts accumulate in the tissues of several pathologies. In vitro, low concentrations of enals such as HNE (4-hydroxy trans-2-nonenal) affect cell signaling whereas high

Aldehydes produced under various environmental stresses can cause cellular injury in plants, but their toxicology in photosynthesis has been scarcely investigated. We here evaluated their effects on photosynthetic reactions in chloroplasts isolated from Spinacia oleracea L. leaves. Aldehydes that are
