Record overview

LMPD ID	LMP011386
Gene ID	816538
Species	Arabidopsis thaliana (Arabidopsis)
Gene Name	transcription factor PIF1
Gene Symbol	PIL5
Synonyms	PHY-INTERACTING FACTOR 1; phytochrome interacting factor 3-like 5; PIF1; PIL5; T2G17.2; T2G17_2
Alternate names	transcription factor PIF1
Chromosome	2
Summary	Encodes a novel Myc-related bHLH transcription factor that has transcriptional activation activity in the dark. It is a key negative regulator of phytochrome-mediated seed germination and acts by inhibiting chlorophyll biosynthesis, light-mediated suppression of hypocotyl elongation and far-red light-mediated suppression of seed germination, and promoting negative gravitropism in hypocotyls. Light reduces this activity in a phy-dependent manner. The protein preferentially interacts with the Pfr forms of Phytochrome A (PhyA) and Phytochrome B (PhyB), is physically associated with APRR1/TOC1 and is degraded in red (R) and far-red (FR) light through the ubiquitin (ub)-26S proteasome pathway to optimize photomorphogenic development in Arabidopsis. It also negatively regulates GA3 oxidase expression.
