Source Description
UniprotDEVELOPMENTAL STAGE: Tightly regulated during anther development. {ECO:0000269|PubMed:16972096}.
UniprotTISSUE SPECIFICITY: Expressed specifically in flowers. Expressed in all four whorls of the flower and in the vascular tissue of stamen filament and sepals. Detected in male and female gametophytes, especially in microspores and ovules. Weakly expressed in petals and the upper part of pistils. {ECO:0000269|PubMed:16805732, ECO:0000269|PubMed:16972096, ECO:0000269|PubMed:19325888}.

Source Description
TAIRMyb24 transcription factor. Member of the R2R3 factor gene family. Induced by jasmonate. Involved in jasmonate response during stamen development.
UniProtTranscription factor acting redundantly with MYB21 and MYB57 to control stamen filament elongation in the late developed flowers. Contributes with MYB21 to induction of MYB108 by jasmonate. Repressed at the transcript levels by DELLA proteins. {ECO:0000269|PubMed:16805732, ECO:0000269|PubMed:16972096, ECO:0000269|PubMed:19091873, ECO:0000269|PubMed:19325888, ECO:0000269|PubMed:21447791}.

UniProtDISRUPTION PHENOTYPE: No visible phenotype. Myb24 and myb57 double mutant has petals that grew to a final height parallel to the pistil. Myb21 and myb24 double mutant is partialy sterile and has petals that just grew out of the sepals but ended at a lower level than the stigma. Myb21, myb24 and myb57 triple mutant has a strongly reduced fertility and an arrested growth of the petals that never grew out of the sepals. Myb24 and myb108 double mutant has a reduced fertility and a greatly reduced seed set. {ECO:0000269|PubMed:16805732, ECO:0000269|PubMed:19091873, ECO:0000269|PubMed:19325888}.
