Mains targets of ABC(E)genes

Protein function

Encodes a trihelix transcription factor involved in the regulation of perianth architecture.

Phenotype

Remarks:
ptl single mutant is characterized by a decreased number of petals. [Brewer et al., 2004]

Function:
Transcription 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. [Data from UniProt]
