Genetic regulation of the catalase developmental program in maize scutellum: Identification of a temporal regulatory gene

Abstract
Genetic and biochemical analyses suggest that the developmental program of catalase (H2O2:H2O2 oxidoreductase, EC 1.11.1.6) activity in maize scutella is controlled by a temporal regulatory gene (Car1) that is distinct from the structural genes thus far identified. Car1 is located about 37 map units from the Cat2 structural gene on the chromosome 1S. Apparently, Car1 may act by regulating the rate of catalase synthesis.
