Abstract

Genetic and biochemical analyses suggest that the developmental program of catalase (H(2)O(2):H(2)O(2) 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. Recombination data show that Car1 is located about 37 map units from the Cat2 structural gene on the chromosome 1S. Turnover studies indicate that Car1 may act by regulating the rate of catalase synthesis.
