Abstract
Eukaryotes generally display a circadian rhythm as an adaption to the reoccurring day/night cycle. This is particularly true for visual physiology that is directly affected by changing light conditions. Here we investigate the influence of the circadian rhythm on the expression and function of visual transduction cascade regulators in diurnal zebrafish and nocturnal mice. We focused on regulators of shut-off kinetics such as recoverins, arrestins, opsin kinases, and GTPase-accelerating protein that have direct effects on temporal vision. Transcript as well as protein levels of most analyzed genes show a robust circadian rhythm dependent regulation, which correlates with changes in photoresponse kinetics. Electroretinography demonstrates that photoresponse recovery in zebrafish is delayed in the evening and accelerated in the morning. This physiological rhythmicity is mirrored in visual behaviors, such as optokinetic and optomotor responses. Functional rhythmicity persists in continuous darkness, it is reversed by an inverted light cycle and disrupted by constant light. This is in line with our finding that orthologous gene transcripts from diurnal zebrafish and nocturnal mice are often expressed in an anti-phasic daily rhythm.
