Protein function
Encodes an homeodomain-containing transcription factor.
Phenotype
Single mutant: pny single mutant shows some inflorescence defects.
[Smith et al., 2004] Multiple mutant: pnypny;
pnf multiple mutant has a much longer plastochron and develops inflorescences that fails to produce flowers.
[Smith et al., 2004] Remarks: Normal flower development of
pnf;
pny double mutant can be restored by either overexpressing
LEAFY or suppress
TFL1 expression.
[Jaeger et al., 2013][Kanrar et al., 2008] Function:Transcription factor that is involved in the preservation of the spiral phyllotactic arrangement leading to a regular pattern of organ initiation. Required for maintenance of stem cell fate in the shoot apical meristem, and is essential for specifying floral primordia and establishing early internode patterning events during inflorescence development. Acts as transcription repressor of AG expression in floral and inflorescence meristems. Is also responsive of the nuclear import of SHOOT MERISTEMLESS (STM). In the fruit, plays a central role in patterning by negatively regulating SHP expression in order to prevent replum cells from adopting a valve margin cell fate.
