**1. Introduction**

The vast majority of living entities are subject to unavoidable and predictable conditions of 24-hour changes in their environment, having the ability to adjust to the day-night cycle. To manage these daily changes in periods of light and darkness, almost every living organism has developed an internal system of synchronisation or circadian clock. This tremendous discovery dates back to the beginning of the eighteenth century when Jean-Jacques d'Ortous de Mairan performed the first chronobiology experiment on *Mimosa pudica,* a plant that visibly responds to circadian changes [1, 2].
