Comparative transcriptome analysis reveals key genes and regulatory networks regulating flowering in rice varieties with different photoperiod sensitivity [PDF]

BMC Plant Biology
Background Rice is a short-day plant whose flowering is critically regulated by photoperiod. Through long-term domestication and selective breeding, rice cultivation has adapted to photoperiod variations across different latitudes, resulting in varieties

Photoperiod effects in a freshwater community: Amphibian larvae develop faster and zooplankton abundance increases under an early‐season photoperiod

Ecology and Evolution, 2023
Organisms that shift their phenologies in response to global warming will experience novel photic environments, as photoperiod (daylength) continues to follow the same annual cycle.

Plant responses to photoperiod [PDF]

New Phytologist, 2008
SummaryPhotoperiod 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.

Determination of photoperiod-sensitive phase in chickpea (Cicer arietinum L). [PDF]

Frontiers in Plant Science, 2016
Photoperiod is one of the major environmental factors determining time to flower initiation and first flower appearance in plants. In chickpea, photoperiod sensitivity, expressed as delayed to flower under short days as compared to long days, may change ...

Effect of photoperiod during growth of Chenopodium rubrum mother plants on properties of offspring

Biologia Plantarum, 2010
Using in vitro culture, we determined the effect of photoperiod during growth of Chenopodium rubrum mother plants on vegetative and reproductive development of offspring.

Photoperiod Stress in Arabidopsis thaliana Induces a Transcriptional Response Resembling That of Pathogen Infection

Frontiers in Plant Science, 2022
Plants are exposed to regular diurnal rhythms of light and dark. Changes in the photoperiod by the prolongation of the light period cause photoperiod stress in short day-adapted Arabidopsis thaliana.

The Photoperiod: Handling and Causing Stress in Plants

Frontiers in Plant Science, 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 Insensitivity in Pigeonpea Introgression Lines Derived from Wild Cajanus Species

Agronomy, 2022
Pigeonpea is a photoperiod-sensitive crop; therefore, the introgression of photoperiod insensitivity could increase its adaptability to new environments.

Effects of Different Photoperiods on the Growth and Nutritional Characteristics of Two Celery Cultivars in Plant Factory

Agronomy, 2023
Three different photoperiod treatments (8 h/16 h, 12 h/12 h, and 16 h/8 h of light/dark) were implemented to investigate the impact of growth, biomass, and phytochemical accumulation in two celery cultivars, namely ‘Zhangqiubaoqin’ (BQ) and ...

Photoperiod-Dependent Expression of MicroRNA in Drosophila [PDF]

, 2022
Like many other insects in temperate regions, Drosophila melanogaster exploits the photoperiod shortening that occurs during the autumn as an important cue to trigger a seasonal response.
