#Unit 5. Developmental Biology

Genes that regulate flowering, have different transcription factors and functions:

 

Gene	Transcription Factor Family	Functions
1. CONSTANS (CO)	i- bHLH	P- Activates flowering in response to long photoperiods
2. FLOWERING D (FD)	ii- Zinc finger	Q- Receptor for florigen, activates flowering via AP1
3. PHYTOCHROME INTERACTING  FACTOR4 (PIF4)	iii- bZIP	R- Activates florigen in response to high temperature
4. FLOWERING LOCUS C	iv- MADS	S- Floral repressor
