Definition of early transcriptional circuitry involved in light-induced reversal of PIF-imposed repression of photomorphogenesis in young Arabidopsis seedlings.

The Plant cell - 1 Nov 2009

Abstract excerpt

Light signals perceived by the phytochromes induce the transition from skotomorphogenic to photomorphogenic development (deetiolation) in dark-germinated seedlings. Evidence that a quadruple mutant (pifq) lacking four phytochrome-interacting bHLH transcription factors (PIF1, 3, 4, and 5) is const...
