Common regulatory patterns have emerged among the feedback loops lying within circadian systems. Significant progress in dissecting the mechanism of clock resetting by temperature and the role of the WC proteins in the Neurospora light response has accompanied documentation of the importance of nuclear localization and phosphorylation-induced turnover of FRQ to this circadian cycle. The long-awaited molecular description of a transcription/translation loop in the Synechococcus circadian system represents a quantal step forward, followed by the identification of additional important proteins and interactions. Finally, the adaptive significance of rhythms in Synechococcus and by extension in all clocks nicely ties up an extraordinary year.
