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 ...

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.

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

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

Crop yield mediated by honeybees in a star fruit orchard exhibiting atypical distyly
Acta Botânica Brasílica, 2021 The dependence of commercial crops on pollinators is closely related to their reproductive strategies and has direct impacts on production yields. Fruit production of Averrhoa carambola, the star fruit, is highly dependent on bee pollination.

Atypical distyly in Psychotria goyazensis Mull. Arg. (Rubiaceae), an intramorph self-compatible species [PDF]
Acta Botânica Brasílica, 2013 Distyly is a genetically controlled floral dimorphism, characterized by the reciprocal positioning of pin and thrum morphs, a heteromorphic incompatibility system and a balanced morph ratio (isoplethy).

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

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 ...

Floral Volatile Organic Compounds of Mitchella repens (Rubiaceae)
Plant-Environment InteractionsMitchella 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).
