PLASTOCHRON1 (CYP78A1)
EN
PLASTOCHRON1 is a cytochrome P450 mono-oxygenase and functions as a gibberellin-independent control of cell division timing. In vitro CYP78A1 catalyzes the omega-hydroxylation of the fatty acid lauric acid. In particular, PLA1 controls leaf initiation and vegetative growth. Overexpression of PLA1 in Zea mays changed the architecture of the plant and produced dramatically larger leaves by increasing cell division duration. More localized, ectopic expression resulted in increased growth, stover biomass, and seed yield.
