Cryptochrome-mediated blue-light signal contributes to carotenoids biosynthesis in microalgae

Frontiers in Microbiology, 2022
Microalgae are considered as ideal cell factories for producing natural carotenoids which display favorable biological activities. As the most important abiotic factor, light not only provides energy for photosynthetic metabolism, but also regulates ...

Cryptochrome [PDF]

Communicative & Integrative Biology, 2010
It was recently discovered that the photoreceptor cryptochrome is involved in mediating magnetosensitive entrainment of the internal clock of fruit flies.1 This discovery follows other recent studies implicating a role of cryptochrome in mediating magnetic sensitivity in orientation responses of fruit flies2,3 and growth responses of plants.4 Such ...

Does Green Really Mean Go? Increasing the Fraction of Green Photons Promotes Growth of Tomato but Not Lettuce or Cucumber

Plants, 2021
The photon flux in the green wavelength region is relatively enriched in shade and the photon flux in the blue region is selectively filtered. In sole source lighting environments, increasing the fraction of blue typically decreases stem elongation and ...

Dynamics at the serine loop underlie differential affinity of cryptochromes for CLOCK:BMAL1 to control circadian timing. [PDF]

, 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 ...

A CRY-BIC negative-feedback circuitry regulating blue light sensitivity of Arabidopsis. [PDF]

, 2017
Cryptochromes are blue light receptors that regulate various light responses in plants. Arabidopsis cryptochrome 1 (CRY1) and cryptochrome 2 (CRY2) mediate blue light inhibition of hypocotyl elongation and long-day (LD) promotion of floral initiation. It

Cryptochrome Signaling in Plants† [PDF]

Photochemistry and Photobiology, 2007
Cryptochromes are blue light receptors that mediate various light-induced responses in plants and animals. They share sequence similarity to photolyases, flavoproteins that catalyze the repair of UV light-damaged DNA, but do not have photolyase activity.

Cryptochrome-1 expression: a new prognostic marker in B-cell chronic lymphocytic leukemia

Haematologica, 2009
Chronic lymphocytic leukemia is an adult-onset leukemia with a heterogeneous clinical behavior. When chronic lymphocytic leukemia cases were divided on the basis of IgVH mutational status, widely differing clinical courses were revealed.

Beyond the photocycle-how cryptochromes regulate photoresponses in plants? [PDF]

, 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
