Comment typeDescription
Developmental StageRapidly up-regulated in apical meristems during the transition to flowering. Transiently expressed in inflorescence meristem. Re-appears in stage 3 flowers, in the central dome that later will develop into stamens and carpels. {ECO:0000269|PubMed:19656343}.
Disruption PhenotypePlants are late-flowering. {ECO:0000269|PubMed:11123798}.
FunctionTranscription activator active in flowering time control. May integrate signals from the photoperiod, vernalization and autonomous floral induction pathways. Can modulate class B and C homeotic genes expression. When associated with AGL24, mediates effect of gibberellins on flowering under short-day conditions, and regulates the expression of LEAFY (LFY), which links floral induction and floral development. {ECO:0000269|PubMed:10995392, ECO:0000269|PubMed:18339670, ECO:0000269|PubMed:18466303, ECO:0000269|PubMed:19656343}.
InductionUp-regulated by gibberellins, vernalization and under long-day conditions. Gradual increase during vegetative growth. Induced by AGL24 at the shoot apex at the floral transitional stage. Repressed by SVP during the early stages of flower development. Inhibited by AP1 in emerging floral meristems. {ECO:0000269|PubMed:17428825, ECO:0000269|PubMed:18339670, ECO:0000269|PubMed:19656343}.

Subcellular LocationNucleus {ECO:0000255|PROSITE- ProRule:PRU00251, ECO:0000269|PubMed:18466303}. Cytoplasm {ECO:0000269|PubMed:18466303}. Note=Translocation from the cytoplasm to the nucleus in the presence of AGL24.
SubunitForms a heterodimer with AGL24 through MADS-box domain. Interacts with AGL15, AGL16 and AGL19. {ECO:0000269|PubMed:15805477, ECO:0000269|PubMed:18466303}.
Tissue SpecificityWidely expressed. Not found in the apical meristem of short-day grown plants in vegetative stage.
