Source Description
UniProtTranscription 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). {ECO:0000269|PubMed:16141453, ECO:0000269|PubMed:20590996}.
