Flower development
Specification of flower meristems

Protein function

Encodes a transcription factor from the phosphatidylethanolamine-binding protein (PEBP) family.

Phenotype

Overexpressor:
TFL1 overexpressor is late flowering under both SD and LD conditions. [Kardailsky et al., 1999][Kobayashi et al., 1999]

Remarks:
tfl1 single mutant has less lateral inflorescence primordia and the shoot apical meristem is converted into a terminal meristem. [Shannon et al., 1991][Shannon et al., 1993]

Single mutant:
tfl1 single mutant is early flowering under both SD and LD conditions. [Shannon et al., 1991][Bradley et al., 1997]

Function:
Controls inflorescence meristem identity and is required for maintenance of a indeterminate inflorescence. Prevents the expression of APETALA1 and LEAFY . Also plays a role in the regulation of the time of flowering in the long-day flowering pathway. May form complexes with phosphorylated ligands by interfering with kinases and their effectors (By similarity). [Data from UniProt]
