Investigating the effects of fire on pollinator‐dependent distyly polymorphism [PDF]

Plant Biology
While fire causes some morphological changes in pollinator‐dependent distylous flowers, most traits related to attraction, reward, and stigma‐anther reciprocity remain unaffected, ensuring intermorph pollen transfer and maintaining the floral polymorphism.

Phenology and floral morph variation suggest non-classical distyly in the Sisrè berry plant [Synsepalum dulcificum (Schumach. & Thonn.) Daniell, Sapotaceae] [PDF]

BMC Plant Biology
Background Understanding floral biology and phenological variation patterns in plant species is crucial for hybridization and genetic improvement. In Synsepalum dulcificum (Sisrè berry plant), the lack of such knowledge hinders proper mastering of the ...

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.

Does the occurence of homostyly necessarily accompany the breakdown of heteromorphic incompatibility system? [PDF]

Frontiers in Plant Science
IntroductionHeterostyly 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 ...

Floral Volatile Organic Compounds of Mitchella repens (Rubiaceae)

Plant-Environment Interactions
Mitchella repens (partridgeberry; family Rubiaceae) is a creeping, understory plant native to eastern North America. The twinned, tubular flowers of this distylous plant are bright white and produce volatile organic compounds (VOCs).

Genomic analyses elucidate S‐locus evolution in response to intra‐specific losses of distyly in Primula vulgaris [PDF]

Ecology and Evolution
Distyly, 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 ...

Characterization of PISTILLATA-like Genes and Their Promoters from the Distyly Fagopyrum esculentum

Plants, 2022
Arabidopsis PISTILLATA (PI) encodes B-class MADS-box transcription factor (TF), and works together with APETALA3 (AP3) to specify petal and stamen identity. However, a small-scale gene duplication event of PI ortholog was observed in common buckwheat and

Genomic studies in Linum shed light on the evolution of the distyly supergene and the molecular basis of convergent floral evolution. [PDF]

New Phytol
Summary Distyly, an example of convergent evolution, is governed by a supergene, the S‐locus, in several species. Recent studies highlight similar genomic architectures of independently evolved S‐loci, but its mode of origin and whether similar regulatory pathways underlie the convergent evolution of distyly remains unclear.

Inheritance of distyly and homostyly in self-incompatible Primula forbesii. [PDF]

Heredity (Edinb), 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.

Genomic Patterns of Loss of Distyly and Polyploidization in Primroses. [PDF]

Mol Biol Evol
Abstract Transitions from outcrossing to selfing and from diploidy to polyploidy often co-occur in plants, likely because the ability to produce selfed seed increases the likelihood of newly formed polyploids to become established.
