Molecular Mechanisms by Which Marine Phytoplankton Respond to Their Dynamic Chemical Environment: Video 1

A video from the 2015 review by Brian Palenik, "Molecular Mechanisms by Which Marine Phytoplankton Respond to Their Dynamic Chemical Environment," from the Annual Review of Marine Science. 

Shown: Time-lapse image series of light production from two Synechococcus elongatus strains that carry a gene encoding the firefly luciferase reporter enzyme. The strains were inoculated onto agar plates in the shape of a moon and sun, and their luciferase genes are driven by different regulatory DNA elements that cause gene activity to peak with opposite phases approximately 12 h apart.
