MADS-box genes encode a family of transcription factors that regulate diverse growth and developmental processes in plants, including flowering. In this study, comprehensive characterization and expression profiling analyses of seven sugar apple (Annona squamosa L.) MADS-box genes were performed using rapid amplification of cDNA ends method. Domain and phylogenetic analyses grouped these seven MADS-box genes into six different clades and they showed high similarity with orthologs in Arabidopsis. Expression patterns of these MADS-box genes were investigated during different flower developmental stages and in various reproductive organs, including petal, stamen, sepal, and pistil. Most of the MADS-box genes studied were least expressed in the sepal and AsAGL67 and AsAGL80 expression was weak in all tissues. AsSEP1 and AsAGAMOUS showed highest expressions in the stamen and pistil, and AsAGL12 showed stamen-specific expression. Dynamic expression patterns of MADS-box genes in different reproductive stages suggest involvement in flower development. Interestingly, a number of these MADS-box genes showed responses to gibberellin, abscisic acid, and salicylic acid treatments, suggesting control of their expression by phytohormones.
