文摘

Photoperiod-induced gene expressions parallel physiological responses. Concurrent hypothalamic expression of gonadostimulatory and steroidogenic genes. Differential expression of eya3, cga and tshβ under acute and chronic long days. Positive correlation of cyp19 on erα suggests erα-mediated photoperiod signalling. Induction and maintenance of photoresponse involve different molecular processes.
