Abstract:

Rattus norvegicus has been considered nonphotoperiodic, but Fischer 344 (F344) rats are inhibited in growth and reproductive development by short photoperiod (SD). We tested photoresponsiveness of the genetically divergent Brown Norway (BN) strain of rats. Peripubertal males were tested in long photoperiod or SD, with or without 30% food reduction. Young males were photoresponsive, with reductions in testis size, body mass, and food intake in SD and with enhanced responses to SD when food restricted. Photoperiods ≤11 h of light inhibited reproductive maturation and somatic growth, whereas phot

Abstract:

SUMMARY The aim of this study was to characterize the lenticular ultraviolet transmission of the Siberian hamster (Phodopus sungorus) and to probe the range of near-ultraviolet (UV-A, 315–400nm) and visible wavelengths (400–760nm) for modulating the photoperiodic regulation of its reproductive and immune systems. Ocular lenses from adult hamsters were found to transmit UV-A wavelengths at similar levels to visible wavelengths, with a short-wavelength cut-off of 300nm. Five separate studies compared the responses of juvenile male hamsters to long photoperiods (16h:8h L:D), short photoperiods (1

Abstract:

Different plants respond to photoperiod in diverse manners. There are three major types of the responses of photoperiodism in plants: short-day responses (SD), long-day responses (LD) and dayneutral responses (DN). The LD plants flower most rapidly under high intensity of light provided for a large period of time while the short day plants flower rapidly only if light is provided for a short period of time. The plants with day-neutral responses, does not depends on the conditions of photoperiod in order to flower. Every plant behaves according to the length of light on its own way. In this stu

Abstract:

The four o'clock flower is one of many plants whose blooming time is influenced by photoperiodism. Long photoperiods can inhibit the initiation of flowering and slow down the development of flower primordia, leading to delayed blooming. This study aims to examine the photoperiodic response of four o'clock flowers (Mirabilis jalapa L.) to shorter durations of sunlight exposure. The research was conducted over one month (September–October 2024), with data collection carried out in Jalan Setia Budi, Tanjung Rejo District, Medan, from 5:00 AM to 10:00 PM.

Abstract:

Insect species with a wide distribution offer a great opportunity to trace latitudinal variation in the photoperiodic regulation of traits important in reproduction and stress tolerances. We measured this variation in the photoperiodic time-measuring system underlying reproductive diapause in Drosophila montana, using a Nanda-Hamner (NH) protocol. None of the study strains showed diel rhythmicity in female diapause proportions under a constant day length (12 h) and varying night lengths in photoperiods ranging from 16 to 84 h at 16°C. In the northernmost strains (above 55°N), nearly all female

Abstract:

Whole-animal experiments devised to investigate possible association between photoperiodic time measurement and the circadian system (Bünning's hypothesis) are compared with more recent molecular investigations of circadian clock genes. In Sarcophaga argyrostoma and some other species, experimental cycles of light and darkness revealed a photoperiodic oscillator, set to constant phase at dusk and measuring night length repeatedly during extended periods of darkness. In some species, however, extreme dampening revealed an unrepetitive (i.e., hourglass-like) response. Rhythms of clock gene trans

Abstract:

Seasonal adaptation to changes in light:dark regimes (i.e., photoperiod) allows organisms living at temperate latitudes to anticipate environmental changes. In nearly all animals studied so far, the circadian system has been implicated in measurement and response to the photoperiod. In insects, genetic evidence further supports the involvement of several clock genes in photoperiodic responses. Yet, the key molecular pathways linking clock genes or the circadian clock to insect photoperiodic responses remain largely unknown. Here, we show that inactivating the clock in the North American monarc

In vitro flowering studies can contribute to the understanding of some of the mechanisms involved in reproductive development, in particular those related to vernalization and photoperiodism. However, on account of the excision of plant parts, in vitro studies imply the rupture of correlation phenomena, which can influence the expression of flowering. The following general conclusions can be drawn from the analysis of the in vitro behavior of short and long day plants, either with or without vernalization requirements, and of some photoperiodically indifferent plants: a) Photoperiod and vernal

Photoperiodic time measurement is the ability of plants and animals to measure differences in day versus night length (photoperiod) and use that information to anticipate critical seasonal transformations, such as annual temperature cycles. This timekeeping phenomenon triggers adaptive responses in higher organisms, such as gonadal stimulation, flowering, and hibernation. Unexpectedly, we observed this capability in cyanobacteria—unicellular prokaryotes with generation times as short as 5 to 6 hours.

Abstract:

Earliness and photo insensitivity is a crucial factor for accommodation of crops in different cropping systems across different agro ecological zones. In the current study we used a core set of 98 genotypes consisting of germplasm as well as released varieties of blackgram to screen it for its response to photoperiodism. Data on days to first flowering and days to fifty percent flowering (DFF) was noted for the individual lines in all the three seasons (Kharif, late kharif, and zaid). An absolute mean difference for days to flowering in all possible combinations and mean of all absolute mean d
