Insects, like several other major groups of organisms (flowering plants, birds, and mammals, for example), may use the number of hours of day or night to regulate seasonal cycles of activity, morphology, reproduction, or development. Such regulation is called photoperiodic induction. The use of day length (or photoperiod) to provide ...

WebTaken together, these results indicated that there were allelic differences in photoperiod-specific flowering time genes and that biennialism was a dose-dependent trait with incomplete dominance. Models for flowering time regulation in henbane involving photoperiod-, vernalization-, and most likely gibberellin-specific pathways are discussed.

Web10 mrt. 2024 · The length of the day (photoperiod) is a robust seasonal signal originated by earth orbital and translational movements, a resilient external cue to the global climate change, and a predictable hint to initiate or complete different developmental programs. Many flowering plants (angiosperms) use a photoreceptor protein, such as phytochrome or cryptochrome, to sense seasonal changes in night length, or photoperiod, which they take as signals to flower. In a further subdivision, obligate photoperiodic plants absolutely require a long or short enough night before flowering, whereas facultative photoperiodic plants are more likely to fl…
