Intramolecular uncoupling of chromophore photoconversion from structural signaling determinants drive mutant phytochrome B photoreceptor to far-red light perception.

Abstract excerpt

The phytochrome (phy) photoreceptor family regulates almost all aspects of plant development in a broad range of light environments including seed germination, onset of the photomorphogenic program in seedling stage, the shade avoidance syndrome in competing plant communities, flowering induction and senescence of adult plants. During evolution two clearly distinct classes of phy-s emerged covering these very...
