Protein function
Encodes a probable transcription factor invovled in the control of stamen and carpel architecture.
Phenotype
Remarks: sup single mutant has extra stamens.
[Bowman et al., 1992] Remarks: Overexpression of
SUP leads to multiple developmental defects, including dwarfism.
[Hiratsu et al., 2002] Function:Probable transcriptional regulator considered as cadastral protein that acts indirectly to prevent the B class homeotic proteins APETALA3 and perhaps PISTILLATA from acting in the gynoecial whorl. Principal function is to balance cell proliferation in the third and fourth whorls of developing flowers thereby maintaining the boundary between stamens and carpels. May fulfill this role by repressing genes implicated in cell division. Plays equally a role in the determinacy of the floral meristem. Is also required for normal ovule development.
