Clocks, cryptochromes and Monarch migrations [PDF]
The annual migration of the Monarch butterfly (Danaus plexippus) from eastern North America to central Mexico is one of nature's most inspiring spectacles. Recent studies including one in BMC Biology, have begun to dissect the molecular and neurogenetic basis for this most complex behavior.

Enhancing the vase life of cut roses through spectral optimisation during greenhouse cultivation
Here, we examined three red‐to‐blue (R:B) light emitting diode (LED) ratios (90:10, 80:20 and 70:30) in two cut rose cultivars. All treatments enhanced photosynthesis, with 90:10 showing the strongest effects—raising chlorophyll, carotenoids, anthocyanins and carbohydrate levels, and extending vase life by up to 30%.

ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Shedding Light on Animal Cryptochromes
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.

SUMMARY The phytochrome B (phyB)‐transcription factor signaling module plays a critical role in regulating photomorphogenesis. In this study, TCP21, a member of the Class I TCP transcription factor family, was identified as a direct interacting partner of phyB.

Photoreceptor cross-talk in UV-B photomorphogenesis in tomato (Solanum lycopersicum) : screening through phytochrome and cryptochrome mutants : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University, Palmerston North, New Zealand [PDF]
Figures 1.1, 1.3, 1.4 and 1.5 removed due to copyright reasonsPlant photoreceptors detect changes in the light environment and induce differential gene expression, resulting in the appropriate physiological and morphological responses.

Targeting Cryptochromes in Chronic Diseases
ABSTRACT The circadian clock generates 24‐h molecular rhythms through transcription–translation negative feedback loops (TTFLs) and regulates daily physiological processes such as sleep–wake cycles, body temperature, hormone secretion, metabolism, and immune function.

EVOLUTION OF THE CIRCADIAN CLOCK IN EXTREME ENVIRONMENT: LESSONS FROM CAVEFISH. [PDF]
Evolution has been strongly influenced by the daily cycles of temperature and light imposed by the rotation of the Earth. Fascinating demonstrations of this are seen in extreme environments such as caves where some animals have remained completely ...

Regulation of Aconitate Hydratase Activity in Maize Leaves with Red and Blue Light [PDF]
The dynamics of the activity of aconitate hydratase (AH, EC 4.2.1.3) in maize leaves under various light regimes was studied and it was established that red and blue light had an inhibitory effect on the functioning of the enzyme under study.
