Chloroplasts in leaf cuttings of Nicotiana rusticaL. show swelling of the thylakoid system and formation of plastid vacuoles in the light. These ultrastructural changes may be caused by uptake of K('+) and Cl('-) into the aqueous compartments between the thylakoid membranes. Ion changes and ultrastructural alterations are reversible in darkness.
