Phenotypic and genomic changes associated with the evolutionary loss of heterostyly in primroses
Trait loss has been documented across broad phylogenetic scales and dissected genetically within species, but how the genetic basis of loss varies among lineages and over evolutionary time remains poorly understood. Heterostyly, a floral polymorphism, represents an ideal case study, as it has been lost repeatedly across angiosperms. In Primula, heterostyly is controlled by the S-locus supergene,…
