Transcript of Corn and mustard seedlings grown either in the light or the dark.
• Phytochrome activation affects membrane potential (~5 sec)
• Phytochrome affects transcription (lag time of less than 5 min)
Transcriptional regulation
• Phytochrome interacting factors (PIFs) act as negative regulators of phytochrome response: PIF mutants exhibit a constituative photomorphogenic response even when plants are grown in the dark.
• Phytochrome initiates degradation of PIFs in the nucleus
