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}.
