Polyacrylamide gel electrophoresis of Tempo bean leaf proteins, extracted from plants grown in filtered air, revealed that low doses of ozone (20-25 pphm for 90-130 min) increased the activity of many peroxidase isoenzymes. Symptomless leaves previously exposed to ozone showed a similar increase in activity, but not as much as in leaves exhibiting definite symptoms of ozone injury. 13 references, 2 figures.
