GO:0009648 photoperiodism

Term Information

ID GO:0009648
Name photoperiodism
Ontology Biological Process
Definition Any process that results in a change in state or activity of an 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.
