Abstract
|
|
|
|
The rising and setting of the sun marks a transition between starkly contrasting environmental conditions for vegetative life. Given these differing diurnal and nocturnal environmental factors and the inherent regularity of the transition between the two, it is perhaps unsurprising that plants have developed an internal timing mechanism (known as a circadian clock) to allow modulation of gene expression and metabolism in response to external cues. Entrainment of the circadian clock, primarily via the detection of changes in light and temperature, maintains synchronization between the surrounding environment and the endogenous clock mechanism. In this review, recent advances in our understanding of the molecular workings of the plant circadian clock are discussed as are the input pathways necessary for entrainment of the clock machinery.
