Protein TERMINAL FLOWER 1; Controls inflorescence meristem identity and is required for maintenance of an 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).

B3 domain-containing transcription factor VRN1; Involved in the regulation of vernalization. Acts as transcriptional repressor of FLC, a major target of the vernalization pathway. Binds DNA in vitro in a non-sequence-specific manner.

Polycomb group protein VERNALIZATION 2; Polycomb group (PcG) protein. Plays a central role in vernalization by maintaining repressed the homeotic gene FLC, a floral repressor, after a cold treatment. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. Associa [...]

Inactive protein FRIGIDA.

Protein TWIN SISTER of FT; May form complexes with phosphorylated ligands by interfering with kinases and their effectors; Belongs to the phosphatidylethanolamine-binding protein family.

Squamosa promoter-binding-like protein 3; Trans-acting factor that binds specifically to the consensus nucleotide sequence 5'-TNCGTACAA-3' of AP1 promoter. Binds specifically to the 5'-GTAC-3' core sequence. Promotes both vegetative phase change and flowering. Regulates phase-specific patterns of leaf epidermal differentiation and flowering time, but does not seem to affect leaf shape.

CASP-like protein 4D1; Belongs to the Casparian strip membrane proteins (CASP) family.

Floral homeotic protein APETALA 2; Probable transcriptional activator that promotes early floral meristem identity. Is required subsequently for the transition of an inflorescence meristem into a floral meristem. Plays a central role in the specification of floral identity, particularly for the normal development of sepals and petals in the wild-type flower, by spatially controlling the expression domains of multiple floral organ identity genes. Acts as A class cadastral protein by repressing the C class floral homeotic gene AGAMOUS in association with other repressors like LEUNIG and [...]

Protein VERNALIZATION INSENSITIVE 3; Plays a central role in vernalization by mediating the initial transcriptional repression of the homeotic gene FLC, a floral repressor, after a cold treatment. However, due to its transient expression, it cannot maintain repression of FLC, which is then maintained by Polycomb Group complexes containing VRN2 throughout development. Required to deacetylate histones on the FLC promoter. Together with VIL1, required during vernalization for the modifications of FLC and FLM chromatin that are associated with an epigenetically silenced state (e.g. chromat [...]
