The transmission of information about the photic environment to the circadian clock involves a complex array of neurotransmitters, receptors, and second messenger systems. Using laser capture microscopy and microarray analysis, a population of genes rapidly induced by light in the suprachiasmatic n...

Analysis of the effect of light pulse and genotype on lichen metatranscription
Light has a strong effect on whole organism physiology, such as the circadian rhythms that are phase delayed and advanced by light given at early and late subjective night, respectively. Despite the importance of the phase-dependent light responses, little is known about the underlying molecular mec...

We report the results of a genome-wide analysis of AS in Arabidopsis thaliana plants exposed to a 2h light pulse given in the middle of the night, a treatment that simulates the effects of early dawn or late dusk signals. This light affects the plant transcriptome at multiple regulatory layers, and...

Transcriptional characterization of Arabidopsis thaliana seeds treated with a red- or far red-light pulse
The proteome of Bacillus pumilus spores subjected to different inactivation treatments was established by shotgun proteomics and compared with the proteome of untreated spores. Treatments included UV-C and Pulse-Light inactivation, either on spores in water, or on spores sprayed onto a polystyrene s...

Transcriptional profiling of light response in the zebrafish at several organizational levels: the whole animal, the organ and the cell. Exposure of larvae, heart organ cultures and cell culture cells to light pulses of 1 and 3 hours duration and measurement of changes in gene expression compared to...
ORGANISM(S): Danio rerio 
The goal of this study was to compare the transcriptional profile (RNA-seq) of imbibed Arabidopsis thaliana Columbia-0 ecotype seeds that were treated with a 20 min red or far red pulse. The red-light pulse induces germination.

Light is a strong environmental cue that resets the circadian clock rhythm. We have used Affymetrix microarrays to profile the Drosophila head transcriptome response following a brief light pulse during the early night. Comparison of control (un-pulsed) and experimental flies reveal large number of...
