Abstract
Effects of the calcium ionophore, A23187, and antimycin A on the circadian conidiation rhythm of Neurospora crassa were examined. A23187 at a concentration of 1 μm in medium not containing divalent cations delayed the phase by 10 hours at CT 10 and advanced it by 5 hours at CT 14 (CT 12 corresponds to the time that discs are transferred from light to dark). This phase shifting was completely inhibited by addition of 0.1 millimolar CaCl2 but not by MgCl2 at any concentrations examined.Keywords
