What's a GeneRIF?

Repressors of flowering time belonging to the AP2-type transcription factor family including SCHLAFMUTZE (SMZ) and SCHNARCHZAPFEN (SNZ) are important regulators of flowering time in response to nitrate. The results support a model whereby nitrate activates SMZ and SNZ via the gibberellin pathway to repress flowering time in Arabidopsis thaliana.
Title: SMZ/SNZ and gibberellin signaling are required for nitrate-elicited delay of flowering time in Arabidopsis thaliana.
Expression of SMZ is developmentally regulated and tissue specific. SMZ represses flowering (via FT and other genes) under long-day photoperiod; SMZ repression of flowering is dependent on FLM but independent of FLC. SMZ represses FT transcription.
Title: Repression of flowering by the miR172 target SMZ.
