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. Interacts with BLH1, BLH2, BLH3, BLH4, BLH6, BLH10, KNAT1, KNAT3, KNAT4, KNAT5, KNAT6 and KNAT7. Expressed in roots, stems, flower buds and siliques. Plants over-expressing OFP2 show kidney-shaped cotyledons, round and curled leaves, small rosette size, late flowering, reduced fertilization and round seeds.
