Protein function
Encodes a transription factor involved in the negative regulation of
WUSCHEL expression.
Phenotype
Single mutant: ult1 single mutant is slightly late flowering under SD conditions only.
[Pu et al., 2013] Remarks: ult1 single mutant produces flowers that contain more floral organs and whorls than wild-type plants.
ULT1 overexpressor has pleiotropic defects, including short stature, increased branch outgrowth, and prematurely terminating inflorescence meristems.
[Fletcher et al., 2001][Carles et al., 2004] Multiple mutant: ult1;
ult2 double mutant produces inflorescences bearing more flowers than either single mutants.
[Monfared et al., 2013] Overexpressor: Overexpression of
ULT1 leads to early flowering. ( No available data about growth conditions.)
[Carles et al., 2009] Function:Putative transcription factor that acts as a key negative regulator of cell accumulation in shoot and floral meristems. Negatively regulates the size of the WUSCHEL (WUS)-expressing organizing center in inflorescence meristems. May act by down-regulating expression of WUS.
