The Circadian Clock Gene Period1 Connects the Molecular Clock to Neural Activity in the Suprachiasmatic Nucleus. [PDF]
, 2015 The neural activity patterns of suprachiasmatic nucleus (SCN) neurons are dynamically regulated throughout the circadian cycle with highest levels of spontaneous action potentials during the day.

Journal of Integrative Plant Biology, EarlyView.The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

Frontiers in Molecular Neuroscience, 2018 Cryptochromes (CRYs) are a class of flavoproteins that sense blue light. In animals, CRYs are expressed in the eyes and in the clock neurons that control sleep/wake cycles and are implied in the generation and/or entrainment of circadian rhythmicity ...

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae
New Phytologist, EarlyView.Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Interactions of drosophila cryptochrome
Photochemistry and PhotobiologyAbstractIn this study, we investigate the intricate regulatory mechanisms underlying the circadian clock in Drosophila, focusing on the light‐induced conformational changes in the cryptochrome (DmCry). Upon light exposure, DmCry undergoes conformational changes that prompt its binding to Timeless and Jetlag proteins, initiating a cascade crucial for ...

Structure of full-length Drosophila cryptochrome [PDF]
Nature, 2011 The cryptochrome/photolyase (CRY/PL) family of photoreceptors mediates adaptive responses to ultraviolet and blue light exposure in all kingdoms of life. Whereas PLs function predominantly in DNA repair of cyclobutane pyrimidine dimers (CPDs) and 6-4 photolesions caused by ultraviolet radiation, CRYs transduce signals important for growth, development,

Photoactivated biological processes as quantum measurements. [PDF]
, 2015 We outline a framework for describing photoactivated biological reactions as generalized quantum measurements of external fields, for which the biological system takes on the role of a quantum meter.

Circadian clocks and breast cancer [PDF]
, 2016 Circadian clocks respond to environmental time cues to coordinate 24-hour oscillations in almost every tissue of the body. In the breast, circadian clocks regulate the rhythmic expression of numerous genes.

Plant Biotechnology Journal, EarlyView.ABSTRACT High temperatures significantly accelerate the timing of floral transition, namely, bolting and flowering, in lettuce, which results in severe loss of marketable yield. Thus, understanding the genetic regulation of floral transition is of great interest to plant biologists and lettuce breeders.

Fungal cryptochrome with DNA repair activity reveals an early stage in cryptochrome evolution [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Photolyases repair UV-B–induced DNA lesions. They form a large protein family together with cryptochrome photoreceptors (cryptochrome/photolyase family, CPF). A more recently discovered CPF subclade consists of DASH ( Drosophila , Arabidopsis , Synechocystis
