title: [Effect of the cyclic nucleotide level on the degree of carotenoid pigment formation in the mycelial cells of Neurospora crassa].
abstract: The relation between the content of cyclic nucleotides and the rate of formation of carotenoid pigments in the Neurospora crassa mycelium cells was investigated. Light derepression of the carotenoid synthesis during the photoinduction lag-period induced a transient decrease of the cAMP content. The intracellular cAMP content was in negative correlation with the constitutive level of carotenoid pigments. The cGMP content remained unchanged during the photoinduction lag-period and showed no correlation with the constitutive level of carotenoids in N. crassa cells.
