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}.
