MADS-box transcriptional regulators play important roles during plant development. Based on phylogenetic reconstruction, the AP1/SEP/AGL6 superclade of floral MADS-box genes underwent one or two duplication events in the common ancestor of the core eudicots. However, the functional evolution of the AP1/SEP/AGL6 superclade in basal eudicots remains uncharacterized. Epimedium sagittatum is a basal eudicot species valued for its medicinal properties and showing unique floral morphology. In this study, structural and functional variation of FUL-like (AP1 subfamily), SEP-like and AGL6-like genes in this species was investigated to further our understanding of flower evolution in angiosperms. Detailed investigations into the microsynteny and evolutionary history of the floral A and E class MADS-box genes in eudicots were undertaken and used to trace their genomic rearrangements.
