Abstract

Temporal co-ordination over daily and annual time-scales is a crucial aspect of animal physiology, achieved through photoperiodic responses. Molecular data suggest that co- ordination of peripheral tissues depends upon oscillations in clock gene expression within these sites, driven by humoral outputs from the SCN. Of these, melatonin has been specifically linked to relay of photoperiod. This project will explore the link between changing melatonin signal profiles and changing cycles of circadian gene expression in a model target tissue, the pars tuberalis, and characterise the consequences of this for specific outputs from this tissue. These studies will improve our understanding of how temporal co- ordination is achieved and enhance the conceptual underpinning of efforts at improving photoperiod-dependent aspects of human wellbeing and animal husbandry.
