Source	Description
Uniprot	DEVELOPMENTAL STAGE: Expressed in growing new meristem. Down-regulated in elongating new meristem. {ECO:0000269\|PubMed:13130077}.
Uniprot	TISSUE SPECIFICITY: Expressed in the boundary between the shoot apical meristem (SAM) and the region of new meristem formation. {ECO:0000269\|PubMed:13130077}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor that seems to regulate organogenesis in postembryonic development. Involved in the regulation of shoot branching by controlling axillary meristem initiation. Functions in association with LAX2 to regulate the process of AM formation. Possesses transactivation activity in yeast (PubMed:21963665). {ECO:0000269\|PubMed:13130077, ECO:0000269\|PubMed:21963665}.

Function -- GeneRIF ? help Back to Top
BA1 is phosphorylated by BIF2. Both co-localize in the nucleus and both are expressed during axillary meristem initiation. This interaction is important for inflorescence development. [PMID: 18466309] BARREN STALK1 is required for the creation of auxin response maxima at the flanks of the inflorescence meristem. [PMID: 18550681] Genetic and expression analyses suggest that Baf1 is required to reach a threshold level of Ba1 expression for the initiation of maize ears. [PMID: 21540434]
