MADS-box protein SOC1

Gene

SOC1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Transcription 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.4 Publications

Expressioni

Tissue specificityi

Widely expressed. Not found in the apical meristem of short-day grown plants in vegetative stage.

Developmental stagei

Rapidly 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.1 Publication

Inductioni

Up-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 (PubMed:17428825, PubMed:18339670, PubMed:19656343). Repressed by SHL to prevent flowering (PubMed:25281686).4 Publications
