title: Photoregulation of carotenogenesis in Phycomyces.
abstract: Mutants of Phycomyces defective in carotene regulation were studied in relation with the photo carotenogenic response. Quantitative complementation analyses revealed that carC, carA and carS mutations are recessive and complement for this photoresponse in carC * carA and carC * carS heterokaryons. A scheme of the regulation of carotenogenesis by light is proposed.
