Expression -- Description ? help Back to Top
Source Description
UniprotDEVELOPMENTAL STAGE: It is detectable at low levels throughout the shoot apex and at enhanced levels in the inflorescence meristem, young floral buds and throughout the early stages of flower development and organogenesis. During floral organ differentiation it becomes spatially restricted to specific organ, tissue and cell types within the flower.
UniprotTISSUE SPECIFICITY: Sepals, petals, stamens, carpels, developing ovules, inflorescence stem, leaf and stem.
Functional Description ? help Back to Top
Source Description
UniProtProbable transcriptional activator that promotes early floral meristem identity (PubMed:7919989). Is required subsequently for the transition of an inflorescence meristem into a floral meristem (PubMed:1675158). 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 (PubMed:1675158, PubMed:23034631). Acts as A class cadastral protein by repressing the C class floral homeotic gene AGAMOUS in association with other repressors like LEUNIG and SEUSS (PubMed:1675158). Directly represses AGAMOUS by recruiting the transcriptional corepressor TOPLESS and the histone deacetylase HDA19 (PubMed:23034631). It is also required during seed development (PubMed:1675158). {ECO:0000269|PubMed:1675158, ECO:0000269|PubMed:23034631, ECO:0000269|PubMed:7919989}.

Regulation -- Description ? help Back to Top
Source Description
UniProtINDUCTION: Negatively regulated by the C class floral homeotic protein AGAMOUS in stamens and carpels. MicroRNA 172 (miRNA172) negatively regulates APETALA2 at the translational level and may modulate its expression pattern. Seems not to be influenced by jasmonate and Alternaria brassicicola. {ECO:0000269|PubMed:12805630, ECO:0000269|PubMed:12893888, ECO:0000269|PubMed:14555699}.
