Signaling Mechanisms by Arabidopsis Cryptochromes [PDF]
Frontiers in Plant Science, 2022 Cryptochromes (CRYs) are blue light photoreceptors that regulate growth, development, and metabolism in plants. In Arabidopsis thaliana (Arabidopsis), CRY1 and CRY2 possess partially redundant and overlapping functions.

A structural decryption of cryptochromes [PDF]
Frontiers in ChemistryCryptochromes (CRYs), which are signaling proteins related to DNA photolyases, play pivotal roles in sensory responses throughout biology, including growth and development, metabolic regulation, circadian rhythm entrainment and geomagnetic field sensing.

Dynamics at the serine loop underlie differential affinity of cryptochromes for CLOCK:BMAL1 to control circadian timing [PDF]
eLife, 2020 Mammalian circadian rhythms are generated by a transcription-based feedback loop in which CLOCK:BMAL1 drives transcription of its repressors (PER1/2, CRY1/2), which ultimately interact with CLOCK:BMAL1 to close the feedback loop with ~24 hr periodicity ...

Orange photons (623 nm) resulted in similar or greater lettuce growth than red photons (660 nm): comparative effects on morphology, photon capture, and photosynthesis [PDF]
Frontiers in Plant SciencePhotosynthetic efficiency is wavelength-dependent. Previous studies found that photons between ~600–625 nm (herein referred to as ‘orange photons’) resulted in the highest quantum yield (i.e., moles of CO2 fixed per mole of absorbed photons), followed by

Beyond the photocycle — how cryptochromes regulate photoresponses in plants? [PDF]
Current Opinion in Plant Biology, 2018 Cryptochromes (CRYs) are blue light receptors that mediate light regulation of plant growth and development. Land plants possess various numbers of cryptochromes, CRY1 and CRY2, which serve overlapping and partially redundant functions in different plant

Magnetically Stimulated Myogenesis Recruits a CRY2-TRPC1 Photosensitive Signaling Axis [PDF]
CellsThe cryptochromes are flavoproteins that either individually or synergistically respond to light and magnetic field directionality as well as are implicated in circadian rhythm entrainment and development. Single brief exposures (10 min) to low energy (1.

Cryptochromes Suppress HIF1α in Muscles [PDF]
iScience, 2020 Summary: Muscles preferentially utilize glycolytic or oxidative metabolism depending on the intensity of physical activity. Transcripts required for carbohydrate and lipid metabolism undergo circadian oscillations of expression in muscles, and both ...

The photolyase/cryptochrome of Aspergillus nidulans senses oxidative stress and shuttles from nuclei to mitochondria [PDF]
Nature CommunicationsCryptochromes are photoreceptors with functions in the entrainment of circadian clocks or as proposed magnetoreceptors in birds or as light-independent regulators of stress responses in plants.

Shedding light on animal cryptochromes. [PDF]
PLoS Biology, 2008 Anyone who's neglected a houseplant for any length of time knows that plants can't survive without light. But it's more complicated than that; in addition to serving as an energy source, light is used by plants as a signal to sense and respond to the environment.
