Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.
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.

Generation of Human CRY1 and CRY2 Knockout Cells Using Duplex CRISPR/Cas9 Technology

open access: yesFrontiers in Physiology, 2019
Circadian clocks are endogenous oscillators essential for orchestrating daily rhythms in physiology, metabolism and behavior. While mouse models have been instrumental to elucidate the molecular mechanism of circadian rhythm generation, our knowledge ...

Bird Cryptochrome 1a Is Excited by Blue Light and Forms Long-Lived Radical- Pairs [PDF]

open access: yes, 2007
Cryptochromes (Cry) have been suggested to form the basis of light-dependent magnetic compass orientation in birds. However, to function as magnetic compass sensors, the cryptochromes of migratory birds must possess a number of key biophysical ...

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

NAD+‒circadian rhythm coupling in dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

Molecular assembly of the period-cryptochrome circadian transcriptional repressor complex

open access: yeseLife, 2014
The mammalian circadian clock is driven by a transcriptional–translational feedback loop, which produces robust 24-hr rhythms. Proper oscillation of the clock depends on the complex formation and periodic turnover of the Period and Cryptochrome proteins,

Quantifying electron transfer reactions in biological systems:what interactions play the major role? [PDF]

open access: yes, 2015
Various biological processes involve the conversion of energy into forms that are usable for chemical transformations and are quantum mechanical in nature.

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider

open access: yesMolecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...

RNA-Seq Analysis Reveals Genes Related to Photoreception, Nutrient Uptake, and Toxicity in a Noxious Red-Tide Raphidophyte Chattonella antiqua

open access: yesFrontiers in Microbiology, 2019
Aquaculture industries are under threat from noxious red tides, but harm can be mitigated by precautions such as early harvesting and restricting fish feeding to just before the outbreak of a red tide.
