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

A Global Analysis of the Distribution Patterns of Style‐Length Polymorphisms Across Angiosperms [PDF]
Ecology and EvolutionUnraveling the evolutionary and biogeographical factors that drive the widespread occurrence of outcrossing mechanisms in plants is key to understanding their prevalence.

FlowerMate: Multidimensional reciprocity and inaccuracy indices for style‐polymorphic plant populations [PDF]
Applications in Plant SciencesPremise 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.

Floral Color Change Mediated by Pollen Input–Output and Its Manipulation of Pollinator Foraging Behavior in Heterostylous Plant Arnebia guttata (Boraginaceae) [PDF]
Ecology and EvolutionThe phenomenon of floral color change (FCC) in angiosperms is frequently associated with pollination events. However, research on triggers, functions, and ecological effects of FCC still remains confined to phenomenological speculation or model‐based ...

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.

Heterostyly: speciation within a species [PDF]
Population Ecology, 2004 AbstractAlmost all organisms in nature show nonrandom mating to different degrees. Two extreme results of nonrandom mating are speciation and sexual differentiation. Heterostyly is a form of sexual differentiation considered to have evolved to resolve conflicts between male and female functions of hermaphrodite flowers. Our study examines necessary and

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

Heterostyly in Linum aretioides
Turkish Journal of Botany, 2013 The petal width; sepal, pistil, and stamen lengths; and changes in pollen sizes associated with heterostyly of different morphs in populations of Linum aretioides Boiss. were investigated. Fruit sets were compared in 2 populations and it was investigated whether the Bozdag population has a heteromorphic incompatibility system.

Comparative proteomic analysis of eggplant (Solanum melongena L.) heterostylous pistil development. [PDF]
PLoS ONE, 2017 Heterostyly is a common floral polymorphism, but the proteomic basis of this trait is still largely unexplored. In this study, self- and cross-pollination of L-morph and S-morph flowers and comparison of embryo sac development in eggplant (Solanum ...

EXPERIMENTAL STUDIES ON THE FUNCTIONAL SIGNIFICANCE OF HETEROSTYLY [PDF]
Evolution; International Journal of Organic Evolution, 1992 Heterostyly has been viewed as both an antiselfing device and a mechanism that increases the proficiency of pollen transfer between plants. We used experimental manipulation of the morph structure of garden populations of self-compatible, tristylous Eichhornia paniculata to investigate the function of floral polymorphism.
