The swelling of mitochondria isolated from leaves, roots, and callus tissues of Nicotiana tabacum, L, var. White Gold, was measured by following changes in optical density at 520 mmu in buffered 0.25 m sucrose or 0.125 m KCl. Ozone induced rapid swelling of the isolated mitochondria and increased the permeability of mitochondrial membranes. The extent of mitochondrial swelling and the amount of soluble proteins and other substances absorbing at 260 and 280 mmu released from mitochondria into… CONTINUE READING
