Attainment of reproductive competence, phase transition, and quantification of juvenility in mutant genetic screens [PDF]
, 2014 Plant development between seedling emergence and flowering is characterized by a series of successive qualitative phases: (1) a post embryonic photoperiodinsensitive phase, during which plants are insensitive to photoperiod; (2) a photoperiod ...

Short photoperiod-induced decrease of histamine H3 receptors facilitates activation of hypothalamic neurons in the Siberian Hamster [PDF]
, 2009 Nonhibernating seasonal mammals have adapted to temporal changes in food availability through behavioral and physiological mechanisms to store food and energy during times of predictable plenty and conserve energy during predicted shortage.

A photoperiod-responsive protein compendium and conceptual proteome roadmap outline in maize grown in growth chambers with controlled conditions. [PDF]
PLoS ONE, 2017 Maize (Zea mays L.) is one of the major staple food crops of the world. However, high photoperiod sensitivity, especially for tropical germplasms, impedes attempts to improve maize agronomical traits by integration of tropical and temperate maize ...

Photoperiodic Programming of the SCN and Its Role in Photoperiodic Output [PDF]
Neural Plasticity, 2018 Though the seasonal response of organisms to changing day lengths is a phenomenon that has been scientifically reported for nearly a century, significant questions remain about how photoperiod is encoded and effected neurobiologically. In mammals, early work identified the master circadian clock, the suprachiasmatic nuclei (SCN), as a tentative encoder

Effect of Feed Restriction and Photoperiod on Reproduction and LEPR, MELR mRNA Expression of Layers [PDF]
Brazilian Journal of Poultry Science, 2019 Photoperiod and nutrition are major factors that affect the reproductive efficiency particularly in female animals. In this study we examined the interaction of photoperiod and food restriction on growth, sexual maturation and receptor mRNA expressions ...

Photoperiodism and Diapause in Insects [PDF]
Nature, 1949 DURING the past five years, work has been in progress at Rothamsted on rearing in the laboratory a number of plant-feeding insects. One of the aims has been to maintain supplies of insects in large numbers throughout the year. This has necessitated a study of the factors affecting diapause, the quiescent phase in which most plant-feeding insect species
