This paper examines the changes in gene expression during the first exposure to a long day (such as those found in spring) in Japanese quails and find that two waves of genes are induced as part of the photoperiodic response. This paper also identifies thyrotrophin expression in the pars tuberalis as a critical event in triggering this photoperiodic response.
