APETALA1  ( AP1 ) encodes a key MADS-box transcription factor that specifies the floral meristem identity on the flank of the inflorescence meristem, and determines the identity of perianth floral organs in the model plant  Arabidopsis thaliana . Orchids are members of the Orchidaceae, one of the largest families of angiosperms. Although the expression patterns of a few  AP1 -like genes in orchids have been reported, their actual functions in orchid reproductive development are so far largely unknown. In this study, we isolated and characterized an  AP1  ortholog,  DOAP1 , from  Dendrobium  Chao Praya Smile.  DOAP1  was highly expressed in reproductive tissues, including inflorescence apices and flowers at various developmental stages. Overexpression of  DOAP1  resulted in early flowering in  Arabidopsis , and was able to rescue the floral organ defects of  Arabidopsis ap1  mutants. Moreover, we successfully created transgenic  Dendrobium  Chao Praya Smile orchids overexpressing  DOAP1 , which displayed earlier flowering and earlier termination of inflorescence meristems into floral meristems than wild-type orchids. Our results demonstrate that  DOAP1  plays an evolutionarily conserved role in promoting flowering and floral meristem specification in the Orchidaceae family.
