To adapt to the surrounding environment, plants constantly monitor and respond to changes in the red and far-red regions of the light spectrum through the phytochrome family of photoreceptors. Extensive efforts using genetic, molecular and photobiological techniques have led to the identification of a group of basic helix-loop-helix transcription factors called the Phytochrome Interacting Factors, PIFs, which directly bind to the photoactivated phytochromes. Members of the PIF family have been… CONTINUE READING
