Source Description
UniprotDEVELOPMENTAL STAGE: In anthers, expressed from the meiosis stage to mitosis, with maximum levels at stages 7 and 8, when meiosis initiates, and when endothecium and the middle layer become condensed, respectively.
UniprotTISSUE SPECIFICITY: Highly expressed in anthers; strong expression in the middle layer and tapetum, and weak expression in the endothecium. {ECO:0000269|PubMed:24755456}.
Functional Description ? help Back to Top
Source Description
UniProtTranscription factor that binds to the E-box-containing promoter regions of the transcription factors TDR and EAT1, activating their expression. May have a role in specifying the cell pattern of the inner anther walls and functioning in meiosis progression. Required for male reproduction (PubMed:24755456). Acts downstream of UDT1 and GAMYB, but upstream of TDR1 and EAT1 in pollen development (PubMed:24894043). {ECO:0000269|PubMed:24755456, ECO:0000269|PubMed:24894043}.
