Plants, 2014 Soybean isolines with different combinations of photoperiod sensitivity alleles were planted in a greenhouse at different times during the year resulting in natural variation in daily incident irradiance and duration.

Dawn and photoperiod sensing by phytochrome A [PDF]
Proceedings of the National Academy of Sciences, 2018 AbstractIn plants, light receptors play a pivotal role in photoperiod sensing, enabling them to track seasonal progression. Photoperiod sensing arises from an interaction between the plant’s endogenous circadian oscillator and external light cues. Here, we characterise the role of phytochrome A (phyA) in photoperiod sensing.

Photoperiod Control of Plant Growth: Flowering Time Genes Beyond Flowering
Frontiers in Plant Science, 2022 Fluctuations in environmental conditions greatly influence life on earth. Plants, as sessile organisms, have developed molecular mechanisms to adapt their development to changes in daylength, or photoperiod.

Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance In many plant species, the timing of flowering is sensitive to photoperiod. In many crop species, genetic variation in this sensitivity is critical for adaptation to specific regions and management practices.

Global Change Biology, 2021 Vegetation phenology in spring has substantially advanced under climate warming, consequently shifting the seasonality of ecosystem process and altering biosphere–atmosphere feedbacks.

Spatial and temporal shifts in photoperiod with climate change.
New Phytologist, 2021 Climate change causes both temporal (e.g., advancing spring phenology) and geographic (e.g., range ex pansion poleward) species shifts, which affect the photoperiod experienced at critical developmental stages (`experienced photoperiod').

The Molecular Basis of Photoperiodism [PDF]
Developmental Cell, 2002 A recent study has demonstrated that an external coincidence mechanism, based on the endogenous circadian control of a transcription factor expression (CO) and the modulation of CO function by light, constitutes the molecular basis for the regulation of flowering time by photoperiod.

Photoperiodic Programming of the SCN and Its Role in Photoperiodic Output [PDF]
Neural Plasticity, 2018 Though the seasonal response of organisms to changing day lengths is a phenomenon that has been scientifically reported for nearly a century, significant questions remain about how photoperiod is encoded and effected neurobiologically. In mammals, early work identified the master circadian clock, the suprachiasmatic nuclei (SCN), as a tentative encoder

Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Forest trees can live for hundreds to thousands of years, and they play a critical role in mitigating global warming by fixing approximately 15% of anthropogenic CO2 emissions annually by wood formation.
