Source Description
TAIREncodes a MADS box transcription factor involved flower and ovule development. Functionally redundant with SEP2 and SEP3.
UniProtProbable transcription factor. Functions with SEPALLATA2/AGL4 and SEPALLATA3/AGL9 to ensure proper development of petals, stamens and carpels, and to prevent the indeterminate growth of the flower meristem. Forms a heterodimer via the K-box domain with AGAMOUS, that could be involved in genes regulation during floral meristem development.
