WebbPhytochrome interacting factors（PIFs）belong to the basic helix-loop-helix（bHLH）transcription factor family，they interact specifically with the active conformer of phytochrome（PHYS）photoreceptors in the nucleus and are decomposed. WebbOne such photoreceptor, ubiquitous across the plant and bacterial kingdom is “phytochrome” (phy), which perceives and responds to the red/far-red wavelength of the light spectrum ( 3, 4 ). In Arabidopsis, phys are encoded by a multigene family consisting of five different genes ( PHYA to PHYE) ( 5 ).
