N-acetyltransferase (nat) is a critical conjunct of photoperiodism between the circadian system and endocrine axis in Antheraea pernyi.

PLoS ONE, 2014
Since its discovery in 1923, the biology of photoperiodism remains a mystery in many ways. We sought the link connecting the circadian system to an endocrine switch, using Antheraea pernyi.

Photoperiodic plasticity in circadian clock neurons in insects

Frontiers in Physiology, 2013
Since Bünning’s observation of circadian rhythms and photoperiodism in the runner bean Phaseolus multiflorus in 1936, many studies have shown that photoperiodism is based on the circadian clock system.

PCH1 integrates circadian and light-signaling pathways to control photoperiod-responsive growth in Arabidopsis

eLife, 2016
Plants react to seasonal change in day length through altering physiology and development. Factors that function to harmonize growth with photoperiod are poorly understood.

Photoperiodic Regulation of Tuber Enlargement in Water Yam

Agronomy, 2022
In tuberous crops, tuber enlargement is one of the most important target traits for yield formation. It has long been known that tuber growth in yams is enhanced by short-day (SD) conditions, but the mechanism of tuber enlargement remains unknown.

Different Photoperiodic Responses in Four Lines of Japanese Quail

The Journal of Poultry Science, 2016
Organisms measure day length to better adapt to seasonal changes in the environment; this phenomenon is called photoperiodism. The Japanese quail has a highly sophisticated photoperiodic mechanism and is an excellent model for the study of ...

Sound Wave Exposure as a Strategy for Improving the Tubular Photobioreactor for Cultivating Synechococcus HS-9 as Biofuel Feedstock under Different Photoperiods

International Journal of Technology, 2020
This study aimed to evaluate the effect of sound wave exposure in different photoperiods on Synechococcus HS-9 cell density and lipid content using tubular photobioreactors (PBRs).

Impact of seasonal fluctuations in natural light on cerebral metabolism in Arctic region residents with different autonomic tones

Russian Open Medical Journal, 2021
Background — The study of physiological mechanisms of human acclimatization to extreme climatic conditions is an urgent task in current socioeconomic conditions of the Arctic region development.

Regulation of monocot and dicot plant development with constitutively active alleles of phytochrome B

Plant Direct, 2020
The constitutively active missense allele of Arabidopsis phytochrome B, AtPHYBY276H or AtYHB, encodes a polypeptide that adopts a light‐insensitive, physiologically active conformation capable of sustaining photomorphogenesis in darkness.

Circadian clock gene Per2 is not necessary for the photoperiodic response in mice. [PDF]

PLoS ONE, 2013
In mammals, light information received by the eyes is transmitted to the pineal gland via the circadian pacemaker, i.e., the suprachiasmatic nucleus (SCN).
