Conservation and Diversification of Circadian Rhythmicity Between a Model Crassulacean Acid Metabolism Plant and a Model C Photosynthesis Plant .

Crassulacean acid metabolism (CAM) improves photosynthetic efficiency under limited water availability relative to C photosynthesis. It is widely accepted that CAM plants have evolved from C plants and it is hypothesized that CAM is under the control of the internal circadian clock. However, the role that the circadian clock plays in the evolution of CAM is not well understood.

Background: Identifying periodically expressed genes across different processes (e.g. the cell and metabolic cycles, circadian rhythms, etc) is a central problem in computational biology.
