Dr. Colleen Doherty uses a Raptor Photonics Eagle V camera in her study of the circadian rhythm in plants. Using Arabidopsis modified to express firefly luciferase Photinus Pyralis on a known heat shock gene she was able to observe unexpected expression in the roots of the plants. Both images were taken with 5min exposure and are about 45min apart before and after the heat shock. The increased luminescence is clearly visible in the roots.
