Convergent evolutionary patterns of heterostyly across angiosperms support the pollination-precision hypothesis [PDF]

Nature Communications
Since the insights by Charles Darwin, heterostyly, a floral polymorphism with morphs bearing stigmas and anthers at reciprocal heights, has become a model system for the study of natural selection.

Transcriptome and Network Analyses of Heterostyly in Turnera subulata Provide Mechanistic Insights: Are S-Loci a Red-Light for Pistil Elongation?

Plants, 2020
Heterostyly employs distinct hermaphroditic floral morphs to enforce outbreeding. Morphs differ structurally in stigma/anther positioning, promoting cross-pollination, and physiologically blocking self-fertilization.

Diverse mating consequences of the evolutionary breakdown of the sexual polymorphism heterostyly [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2023
Significance Reproductive systems of flowering plants often evolve in response to differences among populations in pollinator faunas. In addition to affecting fecundity, these differences should influence mating, with multigeneration consequences for ...

Genomic architecture and evolution of heterostyly: new insights from Cordia subcordata (Boraginaceae). [PDF]

Mol Biol Evol
Heterostyly is a floral polymorphism controlled by an S-locus supergene in several angiosperm families. Most heterostylous species are self-incompatible.

Sexual organs of Sarcotheca macrophylla Blume (Oxalidaceae), an endemic species of Borneo with two floral types confirmed as heterostyly

Journal of Asia-Pacific Biodiversity
: Sarcotheca macrophylla Blume (Oxalidaceae), an endemic plant species to Borneo, consists of short-styled (S-morph) and long-styled (L-morph) flowers, referred to as heterostyly.

Floral Characterization of Pomegranate Genotypes to Improve Hybridization Efficiency [PDF]

Plants, 2022
Pomegranate (Punica granatum) has staminate (male), androgynous (hermaphrodite), and intermediate flower types. Floral characterization is difficult for breeding efficiency across many pomegranate genotypes in Pakistan, which is essential for pomegranate

Phylogenomics of the pantropical Connaraceae: revised infrafamilial classification and the evolution of heterostyly. [PDF]

Plant Syst Evol
Connaraceae is a pantropical family of about 200 species containing lianas and small trees with remarkably diverse floral polymorphisms, including distyly, tristyly, homostyly, and dioecy.

FlowerMate: Multidimensional reciprocity and inaccuracy indices for style‐polymorphic plant populations [PDF]

Applications in Plant Sciences
Premise Heterostyly in plants promotes pollen transfer between floral morphs, because female and male sex organs are located at roughly reciprocal heights within the flowers of each morph.
