Source Description
UniprotDEVELOPMENTAL STAGE: First observed in the early-developing flower, in four zones between the initiating sepals and in their developing margins. Later detected in the margins of expanding sepals, petals and stamens, and in the leaf margins. {ECO:0000269|PubMed:15269176}.
UniprotTISSUE SPECIFICITY: Confined to flowers, at low levels. Also present in 7-days-old seedlings. Barely detectable in other tissues such as young seedlings, roots, stems, leaves and siliques (PubMed:15269176). Expressed in flower primordia, more precisely between newly arisen sepal primordia and also at the basal margins of developing sepals (PubMed:25697797). {ECO:0000269|PubMed:15269176, ECO:0000269|PubMed:25697797}.
Functional Description ? help Back to Top
Source Description
UniProtTranscription factor that prevents growth. Regulates perianth architecture in flower, mostly in the second whorl, probably by suppressing growth between initiating sepals, ensuring that they remain separate, and by modulating organ shapes. Required for the establishment of auxin flux. {ECO:0000269|PubMed:10572040, ECO:0000269|PubMed:15269176, ECO:0000269|PubMed:18080804}.

Source Description
UniProtINDUCTION: Expression within the newly arising sepals is repressed via the PINOID auxin-response pathway. {ECO:0000269|PubMed:15269176}.
