Phytochromes and cryptochromes in the entrainment of the Arabidopsis circadian clock.

Science (New York, N.Y.) - 20 Nov 1998

Somers D E, Devlin P F, Kay S A

Abstract excerpt

Circadian clocks are synchronized by environmental cues such as light. Photoreceptor-deficient Arabidopsis thaliana mutants were used to measure the effect of light fluence rate on circadian period in plants. Phytochrome B is the primary high-intensity red light photoreceptor for circadian control, and phytochrome A acts under low-intensity red light. Cryptochrome 1 and phytochrome A both act to transmit...
