UniProt Comments
Transcription factor involved in photomorphogenesis in the light. May act downstream of the light receptor network and directly affects transcription of light-induced genes. In darkness, its probable degradation prevent the activation of light-induced genes. Required to activate expression of PAL. Acts redundantly with MYB24 and MYB57 to control stamen filament elongation in the late developed flowers. Contributes with MYB24 to induction of MYB108 by jasmonate. Repressed at the transcript levels by DELLA proteins.
