Source Description
UniprotDEVELOPMENTAL STAGE: Faint expression in buds and flowers. Increases during the very early stages of seed development, reaches a maximum at the globular embryo stage and stays high throughout seed formation.
UniprotTISSUE SPECIFICITY: Buds, flowers and developing siliques, but not in leaves, stems and roots. {ECO:0000269|PubMed:12679534}.
Functional Description ? help Back to Top
Source Description
UniProtTranscription activator, when associated with MYB75/PAP1 or MYB90/PAP2. Involved in the control of flavonoid pigmentation. Plays a key role in regulating leucoanthocyanidin reductase (BANYULS) and dihydroflavonol-4-reductase (DFR). Not required for leucoanthocyanidin dioxygenase (LDOX) expression. {ECO:0000269|PubMed:15361138}.
