The roles of environmental stimuli in initiation and synchronization of circadian oscillation during development appear to vary among different rhythmic processes. In zebrafish, a variety of rhythms emerge in larvae only after exposure to light-dark

The circadian oscillator in Xenopus retinal photoreceptor layers can be reset in similar ways by light and agonists of D2-like dopamine receptors. Treatments that increase cyclic AMP levels act on this oscillator in an opposite fashion, mimicking dar

As part of an ongoing program to identify genes involved in maintaining circadian rhythms of zebrafish, 6,500 mutagenized genomes were screened for dominant mutants affecting circadian locomotor activity. Molecular analysis of one of these mutant lin

In various multicellular organisms, circadian clocks are present not only in the central nervous system, but also in peripheral organs and tissues. In mammals peripheral oscillators are not directly responsive to light, but are entrained by the centr

Key indicators of circadian regulation include the persistence of physiological rhythmicity in the absence of environmental time cues and entrainment of this rhythmicity by the ambient light cycle. In some teleosts, the inner segments of rod and cone

Circadian rhythms are generated by transcriptional and translational feedback loops. Stress-activated protein kinases (SAPKs) are known to regulate transcription factors in response to a variety of extracellular stimuli. In the present study, we exam

Widespread use of zebrafish (Danio rerio) in genetic analysis of embryonic development has led to rapid advances in the technology required to generate, map and clone mutated genes. To identify genes involved in the generation and regulation of verte

The Xenopus retinal photoreceptor layer contains a circadian oscillator that regulates melatonin synthesis in vitro. The phase of this oscillator can be reset by light or dopamine. The phase-response curves for light and dopamine are similar, with tr

The authors show that a circadian clock that regulates locomotor activity in larval zebrafish develops gradually over the first 4 days of life and that exposure to entraining signals late in embryonic development is necessary for initiation of robust

Recent research on the circadian system of the zebrafish is reviewed. This teleost has become an attractive model system because of its advantages for genetic analyses. Circadian rhythms of zebrafish behavior, visual system function, and pineal melat
