Expression -- Description ? help Back to Top
Source	Description
Uniprot	TISSUE SPECIFICITY: Expressed specifically in flowers. Restricted to anthers in maturing flowers. Strongest expression in the vascular and connective tissue where the anther attaches to the filament. Not detected in pollen. {ECO:0000269\|PubMed:19091873}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor contributing to the regulation of stamen maturation and male fertility in response to jasmonate signaling. Required for correct timing of anther dehiscence. Acts as a negative regulator of abscisic acid-induced cell death. Not involved in the regulation of BOI. Regulated by MYB21 and at a lower level by MYB24. Negatively regulated by the proteasome in an SCF(COI1) E3 ubiquitin-protein ligase complex-dependent manner. {ECO:0000269\|PubMed:14555693, ECO:0000269\|PubMed:19091873, ECO:0000269\|PubMed:20921156, ECO:0000269\|PubMed:23952703}.
