Source Description
UniprotDEVELOPMENTAL STAGE: In the developing axillary shoot apical meristem (SAM), expressed at the boundary between nascent axillary meristems and the adaxial side of leaves. In all mature SAMs, located at the boundaries between the central SAM and the initiating organ primordia, as well as between the neighboring initiating organ primordia. In the floral meristem, strongly expressed at the boundaries between the meristematic dome and the initiating floral organ primordia, and also at the boundaries between the primordia of different whorls. Expression at the boundaries attenuates as the organ primordia grow apart. In flowers, localized at the boundary between the central meristematic cells and differentiating stamen primordia to later accumulates at the medial ridge region of the carpel. Highly expressed in the developing anthers, in both the tapetum cell layer and microsporocytes. In developing ovules, confined to inner and outer integuments. In aerial tissues, strongly present in phloem tissues (PubMed:15367721). First observed in the whole embryo, but later confined to the center cells of the embryo and provascular tissues (PubMed:15367721, PubMed:20643354). {ECO:0000269|PubMed:15367721, ECO:0000269|PubMed:20643354}.
UniprotTISSUE SPECIFICITY: Expressed in vegetative and inflorescence shoot apical meristems (SAMs), axillary (SAMs), floral meristems, developing ovules and stamens, vascular tissues, and in the embryo. {ECO:0000269|PubMed:15367721, ECO:0000269|PubMed:26390296}.

Source Description
TAIREncodes a GATA factort transcriptional regulator required to position the proembryo boundary in the early embryo.
UniProtTranscriptional factor that specifically binds 5'-GATA-3' or 5'-GAT-3' motifs within gene promoters (including its own promoter and GATA21 promoter), thus regulating the expression of genes mostly involved in hormone responses and floral organ specification (including genes regulating hormones responses) (PubMed:23335616, PubMed:26390296). Regulates both flower and shoot apical meristem (SAM) development, especially for establishing organ boundaries in shoots and flowers, probably by controlling the number and position of WUS-expressing cells (PubMed:15367721, PubMed:23335616). Coregulates, with AGO10/PNH, the shoot apical meristem (SAM) organization. Regulates floral organ development via the promotion of JAG and NPR5/BOP2 expression. Modulates cytokinin homeostasis in organ boundaries by regulating CKX3 expression (PubMed:26390296). Involved in cell proliferation and differentiation (PubMed:15367721). Required to position the inductive proembryo boundary via the regulation of gene expression and for early embryonic development (PubMed:20643354). Together with GIF1/AN3, mediates cotyledon identity by preventing ectopic root formation through the repression of PLT1 expression (PubMed:22669825). {ECO:0000269|PubMed:15367721, ECO:0000269|PubMed:20643354, ECO:0000269|PubMed:22669825, ECO:0000269|PubMed:23335616, ECO:0000269|PubMed:26390296}.

    [PMID: 20643354]
  2. The data suggested that establishing cotyledon identity requires both GIF1 and HANABA TARANU to repress ectopic root formation by repressing PLETHORA1 expression.
    [PMID: 22669825]
  3. HAN functions as a key repressor that regulates floral development via regulatory networks involving genes in the GATA3 family, along with genes involved in hormone action and floral organ specification.
    [PMID: 23335616]
  4. HAN physically interacts with JAG, and directly stimulates the expression of JAG and BOP2 to regulate floral organ development
