The paper identifies a supergene controlling floral handedness in butterfly lilies, explaining how genetic factors influence left-right organ placement for cross-pollination.

The paper shows that reductions in petal size in selfing Brassicaceae species arise from dosage changes at the pleiotropic gene JAG, highlighting the role of developmental networks and standing variation in shaping predictable evolutionary outcomes.

This study identifies that floral handedness in Cyanella alba is determined by phyllotactic spiral direction and auxin-induced differential cell elongation, not genetics.
