Plant chronobiology: physiological aspects of a green clock

Abstract

Although animals are the most frequent biological system in chronobiologic works, biological rhythms were originally described in plants and the history of chronobiology is permeated by important discoveries in the plant biology field. Many central concepts, nowadays widely applied to diverse organisms, have initially been identified in plants. The present review aims to introduce the main discoveries in plant chronobiology, adopting a historical approach, and to introduce the main physiological events involved in plant’s endogenous timekeeping as well
