A plant blue light response was documented as early as 1881 by Darwin when he
discovered what is now known as the blue light–induced phototropic response (Darwin …

Edery, Isaac. Circadian rhythms in a nutshell. Physiol Genomics 3: 59–74, 2000.—Living
organisms on this planet have adapted to the daily rotation of the earth on its axis. By means …

Most organisms have circadian clocks consisting of negative feedback loops of gene
regulation that facilitate adaptation to cycles of light and darkness. In this study …

Abstract cry (cryptochrome) is an important clock gene, and recent data indicate that it
encodes a critical circadian photoreceptor in Drosophila. A mutant allele, cry b, inhibits …

Circadian rhythms are entrained by light to follow the daily solar cycle. We show that
Drosophila uses at least three light input pathways for this entrainment:(1) cryptochrome …

The second edition of this best-selling handbook is bigger, more comprehensive, and now
completely current. In addition to thorough updates to the discussions featured in the first …

The Drosophila circadian oscillator consists of interlocked period (per)/timeless (tim) and
Clock (Clk) transcriptional/translational feedback loops. Within these feedback loops, CLK …

▪ Abstract Forward genetic analyses in flies and mice have uncovered conserved
transcriptional feedback loops at the heart of circadian pacemakers. Conserved …

▪ Abstract Circadian rhythms are oscillations in the biochemical, physiological, and
behavioral functions of organisms that occur with a periodicity of approximately 24 h. They …

Cryptochromes have been suggested to be the primary magnetoreceptor molecules
underlying light-dependent magnetic compass detection in migratory birds. Here we review …
