The rapid appearance of homostyly in a cultivated distylous population of Primula forbesii [PDF]
Ecology and Evolution, 2022 Evolutionary breakdown from rigorous outbreeding to self‐fertilization frequently occurs in angiosperms. Since the pollinators are not necessary, self‐compatible populations often reduce investment in floral display characteristics and pollination reward.

Genomic analyses elucidate S‐locus evolution in response to intra‐specific losses of distyly in Primula vulgaris [PDF]
Ecology and EvolutionDistyly, a floral dimorphism that promotes outcrossing, is controlled by a hemizygous genomic region known as the S‐locus. Disruptions of genes within the S‐locus are responsible for the loss of distyly and the emergence of homostyly, a floral ...

Different molecular changes underlie the same phenotypic transition: Origins and consequences of independent shifts to homostyly within species [PDF]
Molecular Ecology, 2023 Abstract The repeated transition from outcrossing to selfing is a key topic in evolutionary biology. However, the molecular basis of such shifts has been rarely examined due to lack of knowledge of the genes controlling these transitions. A classic example of mating system transition is the repeated shift from heterostyly to homostyly.

Does the occurence of homostyly necessarily accompany the breakdown of heteromorphic incompatibility system? [PDF]
Frontiers in Plant ScienceIntroductionHeterostyly is a genetic polymorphism that facilitates precise pollen transfer through reciprocal herkogamy. The loss or variation of reciprocal herkogamy is usually accompanied by the breakdown of heteromorphic incompatibility system ...

Evolution of Autonomous Selfing in Marginal Habitats: Spatiotemporal Variation in the Floral Traits of the Distylous Primula wannanensis [PDF]
Frontiers in Plant Science, 2021 Outcrossing plant species are more likely to exhibit autonomous selfing in marginal habitats to ensure reproduction under conditions of limited pollinator and/or mate availability.

Evolution of distyly breakdown in Palicoureeae Robbr. & Manen and Psychotrieae Cham. & Schltdl. (Rubiaceae) [PDF]
Acta Botânica Brasílica, 2022 Distyly is a floral polymorphism with reciprocal placement of male and female structures, heteromorphic self-incompatibility, and other ancillary traits. However, breeding system breakdowns and loss of polymorphism are common.
