Phytochrome gene diversity

Webb10 apr. 2024 · Phytochromes are photoreceptors that sense the red and far-red region of the light spectrum. They are dimeric chromoproteins that are covalently bound to the phytochromobilin chromophore. In the dark, phytochromes are synthesized as inactive and red light-absorbing Pr forms and are localized in the cytosol. WebbPhytochromes in charophyte algae are structurally diverse, including canonical and non-canonical forms, whereas in land plants, phytochrome structure is highly conserved. …
