A method of increasing gene expression by manipulating the circadian clock is described that includes transforming a photosynthetic organism to include an expression control sequence that modulates the expression of a clock gene to increase expression of a target gene. Photosynthetic organism having a modified circadian cycle reflecting this method are also described.
