Night-Break Experiments Shed Light on the Photoperiod1-Mediated Flowering.
Plants utilize variation in day length (photoperiod) to anticipate seasonal changes. They respond by modulating their growth and development to maximize seed production, which in cereal crops is directly related to yield. In wheat (Triticum aestivum), the acceleration of flowering under long days (LD) is dependent on the light induction of PHOTOPERIOD1 (PPD1) by phytochromes. Under LD, PPD1 act...

متن کاملAcute Induction of Eya3 by Late-Night Light Stimulation Triggers TSHβ Expression in Photoperiodism
Living organisms detect seasonal changes in day length (photoperiod) [1-3] and alter their physiological functions accordingly to fit seasonal environmental changes. TSHβ, induced in the pars tuberalis (PT), plays a key role in the pathway that regulates vertebrate photoperiodism [4, 5]. However, the upstream inducers of TSHβ expression remain unknown. Here we performed genome-wide expression a...
متن کاملShedding light on photoperiodism.
I n mammals, photoreception is restricted to the eye. By contrast, nonmammalian vertebrates possess photoreceptors in a wide array of extraocular tissues, including the pineal complex and brain (1). The identity of the deep brain photoreceptors has remained elusive. They continue to be the least studied of all nonvisual photoreceptor classes, although their existence in the vertebrates has been...
متن کاملInsect photoreceptor adaptations to night vision.
Night vision is ultimately about extracting information from a noisy visual input. Several species of nocturnal insects exhibit complex visually guided behaviour in conditions where most animals are practically blind. The compound eyes of nocturnal insects produce strong responses to single photons and process them into meaningful neural signals, which are amplified by specialized neuroanatomic...
