Meristem identity genes Notes:
These genes confer floral identity on the peripheral zone cells that give rise to primordia, so that they produce flowers rather than vegetative structures. The major floral meristem identity genes in Arabidopsis are LFY and APETELA1 (AP1). Mutations in either of these genes cause a partial conversion of flowers to shoots. In addition to its role in floral meristem identity, AP1, which encodes a MADS box transcription factor, is also involved in the determination of floral organ identity.
