Transcriptional repressor that regulates multiple aspects of plant growth and development through the regulation of BEL1-LIKE (BLH) and KNOX TALE (KNAT) homeodomain transcription factors. Expressed in roots, rosette and cauline leaves, shoots, stems, flower buds and siliques. No visible phenotype under normal growth conditions. Plants over-expressing OFP16 show small rosette size, late flowering, reduced fertilization and blunt-end siliques.
