Protein
Transcription factor UDT1
Organism
Oryza sativa subsp. japonica
Function
Transcription factor that plays a crucial role in tapetum development. Required for male fertility and pollen differentiation within the developing anther. Plays a major role in maintaining tapetum development, starting in early meiosis. Required for pollen mother cell meiosis. May regulate the anther-specific cysteine protease CP1 and lipid-transfer proteins C4 and C6 (PubMed:16141453). Required for anther development. Functions in parallel with GAMYB to regulate early anther development. Functions upstream of the transcription factor TDR and may positively regulate its transcription (PubMed:20590996).
Similarity
Belongs to the bHLH protein family.
