Functional Description ? help Back to Top
Source	Description
TAIR	Encodes a AP2 domain transcription factor that can repress flowering. SMZ and its paralogous gene, SNARCHZAPFEN (SNZ), share a signature with partial complementarity to the miR172 microRNA, whose precursor is induced upon flowering.
UniProt	Probably acts as a transcriptional activator. Binds to the GCC-box pathogenesis-related promoter element. May be involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways (By similarity). Repressor of flowering. {ECO:0000250, ECO:0000269\|PubMed:14573523}.

Function -- GeneRIF ? help Back to Top
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. [PMID: 19582143] 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. [PMID: 29309650]
