Abstract
An ultrastructural investigation of paraquat-treated leaf tissue of Lo lium perenne seedlings using negative staining techniques alongside co nventional ultrathin sectioning methods revealed extensive damage to t he Rubisco molecules after only 4 h in light. The early involvement of hydroxyl radicals in chloroplast stroma destruction is discussed.
