Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: First expressed in the apical cell after the first asymmetric division of the zygote. Expressed in all proembryo cells until the eight-cell stage, and then restricted to the protoderm in the 16-cell proembryo. Not detected in the torpedo stage, but reappeared later in the L1 layer of the shoot apical meristem in the mature embryo. After germination, the L1 layer-specific expression pattern is maintained in the vegetative shoot apical meristem, inflorescence, floral meristems, and the young floral organ primordia. Finally, expressed in the protoderm of the ovule primordia and integuments and gradually restricted to the endothelium surrounding the embryo sac. {ECO:0000269\|PubMed:10571886, ECO:0000269\|PubMed:8989876}.

Functional Description ? help Back to Top
Source	Description
UniProt	Probable transcription factor involved in cell specification and pattern formation during embryogenesis. Binds to the L1 box DNA sequence 5'-TAAATG[CT]A-3'. Plays a role in maintaining the identity of L1 cells, possibly by interacting with their L1 box or other target-gene promoters. Functionally redundant to PDF2. {ECO:0000269\|PubMed:11439135, ECO:0000269\|PubMed:12505995}.
