Supergene evolution via stepwise duplications and neofunctionalization of a floral-organ identity gene.

Proceedings of the National Academy of Sciences of the United States of America - 15 Sept 2020

Abstract excerpt

Heterostyly represents a fascinating adaptation to promote outbreeding in plants that evolved multiple times independently. While l-morph individuals form flowers with long styles, short anthers, and small pollen grains, S-morph individuals have flowers with short styles, long anthers, and large pollen grains. The difference between the morphs is controlled by an S-locus "supergene" consisting of several distinct...
