Also known as
BEL1-like homeodomain 8; PNF; POUND-FOOLISH; T1E2.9; T1E2_9
Summary
Encodes a BEL1-like homeobox gene that functions together with PNY in meristem maintenance by regulating the allocation process during vegetative and reproductive development. Both gene products are required for the competence of the SAM to respond properly to floral inductive signals.
