Photoperiodic time measurement is the ability of plants and animals to measure differences in day versus night length (photoperiod) and use that information to anticipate critical seasonal transformat...

The genetic program of animal development is conserved, but its rate of execution varies across species. Heterochrony, shifts in the relative timing of developmental events, generates phenotypic varia...

The potential functions of circadian clocks in non-photosynthetic bacteria are poorly understood. Here, the authors show that the Bacillus subtilis circadian clock regulates the spatiotemporal organis...

Repressive PER2:CRY1:CK1δ complexes assembling in the cytosol enter the nucleus, where PER2 hyperphosphorylation eventually disrupts the complex, causing PER2 to relocalize to the cytoplasm, allowing ...
