...Priya Crosby; Carrie L. Partch ABSTRACT Mammalian circadian rhythms drive ∼24 h periodicity in a wide range of cellular processes, temporally coordinating physiology and behaviour within an organism, and synchronising this with the external day–night cycle. The canonical model for this timekeeping...

...Isabelle A. Carré; Leland N. Edmunds, Jr ABSTRACT The achlorophyllous ZC strain of Euglena gracilis exhibits a circadian rhythm of cell division in constant darkness (DD). Mitosis occurs during a restricted part of the circadian cycle, corresponding to the dark intervals in a light-dark cycle...

.... This property was also verified for the circadian rhythm in cyclic AMP in nondividing cultures of the ZC mutant. A 1-h light signal, given at CT 17, did not immediately perturb the cyclic AMP oscillation. The next cyclic AMP surge, however, was delayed by 4h ( Fig. 2 ). A transient change of cyclic AMP level...
