Protein
BEL1-like homeodomain protein 9
Organism
Arabidopsis thaliana
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.
Similarity
Belongs to the TALE/BELL homeobox family.
