Non-synchronous increases in activities of peroxisomal enzymes in etiolated mung bean seedling leaves after illumination

When etiolated 4-day-old seedlings of mung bean were illuminated,catalase, glycolate oxidase and hydroxypyruvate reductase activitiesin the primary leaves increased non-synchronously. Under intenselight, glycolate oxidase activity increased while catalase activitydid not. Phytochrome seems to be involved in increases in allthree enzyme activities. (Received August 10, 1977; )
