The Cryptochrome1 (cry1) Gene has Oscillating Expression Under Short and Long Photoperiods in Sesamia nonagrioides

There are two major rhythms of the biosphere, a daily cycle of night and day, and an annual seasonal cycle marked by changes in day and night length. The daily cycle is traced by an internal circadian clock that rules a large array of daily biochemical and physiological responses, while the seasonal cycle motivates photoperiodic responses that can be critical to survival, as in the case of insect diapause [1]. Circadian (≅24 h) clock is a core molecular mechanism that allows organisms to forestall daily environmental changes and adapt the timing of behaviors to maximize their efficacy. The basic circadian clock of insects functions as a light-delicate molecular oscillator, including a light-sensitive protein known as CRYPTOCHROME (CRY) and Abstract
