Any process that stops, prevents or reduces long-day photoperiodism, where the response associated with the photoperiodism is flowering. Flowering is defined by the switch from the vegetative to the reproductive phase. Any process that activates, maintains or increases long-day photoperiodism, where the response associated with the photoperiodism is flowering. Flowering is defined by the switch from the vegetative to the reproductive phase. The process involved in transforming a meristem that produces vegetative structures, such as leaves, into a meristem that produces reproductive structures, such as a flower or an inflorescence. A change in state or activity of the organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detection of, or exposure to, a period of light or dark of a given length, measured relative to a particular duration known as the 'critical day length'. The critical day length varies between species. A change from the vegetative to the reproductive phase as a result of detection of, or exposure to, a period of light that exceeds the critical day length. The critical day length varies between species. Although the term is long-day is used, most species actually respond to the duration of the night, so that the response will occur when a period of darkness falls short of the number of hours defined by 24 minus the critical day length. Any process that modulates the frequency, rate or extent of long-day photoperiodism, where the response associated with the photoperiodism is flowering. Flowering is defined by the switch from the vegetative to the reproductive phase. A change from the vegetative to the reproductive phase as a result of detection of, or exposure to, a period of light or dark of a given length. The length of the period of light or dark required to initiate the change is set relative to a particular duration known as the 'critical day length'. The critical day length varies between species. A change in state or activity of the organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of detection of, or exposure to, a day length that exceeds a particular duration known as the 'critical day length'. The critical day length varies between species. Although the term long-day is used, most species actually respond to the duration of the night, so that the response will occur when a period of darkness falls short of the number of hours defined by 24 hours minus the critical day length.

GO TERM SUMMARY
Name: long-day photoperiodism, flowering
Acc: GO:0048574
Aspect: Biological Process
Desc: A change from the vegetative to the reproductive phase as a result of detection of, or exposure to, a period of light that exceeds the critical day length. The critical day length varies between species. Although the term is long-day is used, most species actually respond to the duration of the night, so that the response will occur when a period of darkness falls short of the number of hours defined by 24 minus the critical day length.
Synonyms:

  • response to short-night, flowering
  • long-day photoperiodic control of inflorescence development
