To investigate the regulation of MADS-box genes in banana (Musa acuminata L. AAA group cv. Brazilian) fruit development and postharvest ripening, we isolated from banana fruit a MADS-box gene designated MuMADS1. Amino acid alignment indicated MuMADS1 belongs to the AGAMOUS subfamily, and phylogenetic analysis indicates that this gene is most similar to class D MADS-box genes. Reverse transcriptase-polymerase chain reaction (RT-PCR) analysis showed that MuMADS1 is expressed in the stamen and pistil of male and female flowers and in the rhizome, the vegetative reproductive organ of the banana plant. In preharvest banana fruit, MuMADS1 is likely expressed throughout banana fruit development. In postharvest banana ripening, MuMADS1 is associated with ethylene biosynthesis. Expression patterns of MuMADS1 during postharvest ripening as determined by real-time RT-PCR suggest that differential expression of MuMADS1 may not only be induced by ethylene biosynthesis associated with postharvest banana ripening, but also may be induced by exogenous ethylene.
