Plant circadian clocks: mechanisms and purposes
Plant growth and stress resistance are coordinated outputs that respond to predictable environmental variation that results from the earth's rotation. An interplay exists between exogenous environmental sensing and endogenous responses. Plants use a circadian clock to time such processes such that homeostasis is achieved. This creates fitness and maximizes growth. The circadian clock itself is a multiple transcriptional-translational feedback system that provides temporal information to coordinate stress resistance and metabolic responses. In this talk I will overview clock mechanism and then highlight our current efforts to examine the metabolic, stress response and circadian systems as integrated processes. Their combined effects on growth and development will be explored in a dicot and a monocot, both in the lab and in the field.
