ABSTRACT

Light input to the plant circadian clock
 
Plant growth and stress resistance are coordinated outputs in response to predictable environmental variation that results from the earth's rotation. An interplay thus exists between dawn and dusk sensing and endogenous responses. Plants use a circadian clock to time such processes such that daily homeostasis is achieved. This creates fitness and maximises growth. Here I will describe the circadian clock as a multiple transcriptional-translational feedback system. From there, I will examine one mechanism of how light sets the oscillator as a hypothesis of entrainment. With new models of the circadian system, we are starting to understand how light-signalling enters the clock.
