Understanding the genetic basis of ecologically important traits is a major focus of evolutionary research. Recent advances in molecular genetic techniques should significantly increase our understanding of how regulatory genes function. By contrast, our understanding of the broader macro-evolutionary implications of developmental gene function lags behind. Here we review published data on the floral symmetry gene network (FSGN), and conduct phylogenetic analyses that provide evidence of a link between floral symmetry and breeding systems in angiosperms via dichogamy. Our results suggest that known genes in the FSGN and those yet to be described underlie this association. We posit that the integration of floral symmetry and the roles of other regulatory genes in plant breeding system evolution will provide new insights about macro-evolutionary patterns and processes in flowering plants.
