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.

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 ...

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.

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 ...

Inheritance of distyly and homostyly in self-incompatible Primula forbesii [PDF]
Heredity, 2023 The evolutionary transition from self-incompatible distyly to self-compatible homostyly frequently occurs in heterostylous taxa. Although the inheritance of distyly and homostyly has been deeply studied, our understanding on modifications of the classical simple Mendelian model is still lacking.

Ecological correlates and genetic consequences of evolutionary transitions from distyly to homostyly [PDF]
Annals of Botany, 2017 The outbreeding floral polymorphism heterostyly frequently breaks down, resulting in the evolution of self-fertilization as a result of homostyle formation. Here, the loss of floral polymorphism in distylous Primula oreodoxa, a sub-alpine species restricted to western Sichuan, China, was examined by investigating the ecological correlates and genetic ...

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.

Characterization of 24 microsatellite markers in Primula chungensis (Primulaceae), a distylous–homostylous species, using MiSeq sequencing [PDF]
Plant Diversity, 2016 Primula chungensis is a species with considerable floral and mating-system variation, including distylous (outcrossing), homostylous (selfing) and mixed populations that contain both outcrossing and selfing forms.
