Comment typeDescription
Developmental StageAccumulates in an adaxial ball-shaped set of cells in three to five cell layers around the L3 layer of the shoot apical meristem (SAM) in youg plantlets. Later, expressed transiently at the center of the boundary between the SAM and developing leaf primordia. In the inflorescence meristem, confined to the axils of flower primordia. {ECO:0000269|PubMed:16461581, ECO:0000269|PubMed:16473968}.
FunctionTranscription activator of genes involved in the regulation of meristematic competence, such as CUC2. Positively regulates axillary meristems (AMs) formation and development, especially at early phases of vegetative growth, probably by specifying a stem cell niche for AM formation. Modulates the negative regulation mediated by gibberellic acid on the timing of developmental phase transitions. {ECO:0000269|PubMed:16461581, ECO:0000269|PubMed:16473968}.
InductionBy a shift from short days to long days, in the axils of primordia on the elongating stem. {ECO:0000269|PubMed:16461581}.
SimilarityContains 2 HTH myb-type DNA-binding domains. {ECO:0000255|PROSITE-ProRule:PRU00625}.
Subcellular LocationNucleus {ECO:0000255|PROSITE- ProRule:PRU00625}.
Tissue SpecificityMostly expressed in roots. Also present in shoot tips and flower buds. {ECO:0000269|PubMed:16461581}.
