Abstract

Members of the AGAMOUS (AG) family of MADS-box genes play important roles in regulating the development of reproductive organs in flowering plants. To elucidate the molecular mechanisms of floral development in Asparagus virgatus, we isolated and characterized an Asparagus AG-homologue, AVAG2. AVAG2 contains an open reading frame that encodes a deduced protein with 234 amino acid residues. Phylogenetic analysis indicated that AVAG2 belongs to the D-lineage of the AG gene family. AVAG2 mRNA was detected in the flower, but not in vegetative organs. Moreover, in in situ hybridization experiments, AVAG2 signals were observed in the stamens and carpels during early flower development, and appeared in the ovule only at later developmental stages. This suggests that the AVAG2 gene is involved in ovule formation. Thus, our expression data support the phylogenetic analysis indicating that AVAG2 belongs to the D-class gene family.
