| Function |
Transcription factor acting in the phytochrome signaling pathway. Activates transcription by binding to the G box (5'-CACGTG-3'). Acts as a negative regulator of phytochrome B signaling. Represses chlorophyll biosynthesis and photosynthesis in the dark. Recruits the histone deacetylase HDA15 to the promoters of chlorophyll biosynthetic and photosynthetic genes. HDA15 represses their transcription by histone deacetylation. Promotes the expression of MDP60 to modulate hypocotyl cell elongation in response to light and ethylene signaling. Required for submergence-induced and ethylene-dependent underwater hypocotyl elongation.
