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. Interacts with BOI, but not with BRG1. 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. Up-regulated by jasmonate and pathogen infection. Ubiquitinated in vitro by BOI. Reduced male fertility associated with delayed anther dehiscence, reduced pollen viability and decreased fecundity. Increased susceptibility to Botrytis infection. Myb24 and myb108 double mutant has a reduced fertility and a greatly reduced seed set relative to the myb108 parental allele.
