Nov 12, 2008 · Summary. Photoperiod controls many developmental responses in animals, plants and even fungi. The response to photoperiod has evolved because daylength is a reliable indicator of the time of year, enabling developmental events to be scheduled to coincide with particular environmental conditions. Much progress has been made towards understanding ...

Jan 24, 2022 · Plants have evolved sensitive mechanisms to measure the length of the photoperiod. Photoperiod sensing enables plants to synchronize developmental processes, such as the onset of flowering, with a specific time of the year, and enables them to alleviate the impact of environmental stresses occurring at the same time every year.
Feb 9, 2024 · Photoperiod (daylength) is a stable indicator of the season, and many organisms have evolved photoperiod measuring systems to predict abiotic and biotic changes associated with a given season . Plants have served as a preeminent study system for photoperiodism because of their propensity to flower in specific seasons, and a pathway for seasonal flowering is known.
Jan 25, 2022 · The photoperiod, which is the length of the light period in the diurnal cycle of 24 h, is an important environmental signal. Plants have evolved sensitive mechanisms to measure the length of the photoperiod. Photoperiod sensing enables plants to synchronize developmental processes, such as the onset of flowering, with a specific time of the ...
May 16, 2024 · The sessile plants have evolved multiple strategies to anticipate these changes, synchronizing their life activities accordingly for survival and reproduction. ... This photoperiod-dependent ...
However, more evolved and flexible species like modern plants, which developed the capacity to adapt to different environments, have reduced this number to less than 50% [4]. Paradoxically, more intertwined, complex systems allowed for a more independent response to external cues, thus permitting the colonization of ever demanding new niches and the acquisition of novel and complex ...
Jan 1, 2015 · In many higher plants, photoperiod regulates quite a number of different processes. In the following growth, succulence (Sect. 8.4.2), tuber formation (Sect. 8.4.3), and floral induction (Sect. 8.5) are chosen as examples. 4.1 Growth. The output of the circadian clock regulates transcription of downstream genes.
