DECONSTRUCTING HETEROSTYLY: THE EVOLUTIONARY ROLE OF INCOMPATIBILITY SYSTEM, POLLINATORS, AND FLORAL ARCHITECTURE [PDF]
Evolution; International Journal of Organic Evolution, 2013 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

Is heterostyly rare on oceanic islands? [PDF]
AoB PLANTS, 2015 Heterostyly has been considered rare on oceanic islands. Is heterostyly truly rare on oceanic islands? What makes heterostyly rare on such islands? To answer these questions, we review the reproductive studies of heterostyly on oceanic islands.

Heterostyly in Goniolimon italicum (Plumbaginaceae), endemic to Abruzzo (central Apennines, Italy) [PDF]
Anales del Jardín Botánico de Madrid, 2015 Goniolimon italicum is an endemic species to central Apennines (Italy). Here we provide the first report of heterostyly in this species. Two morphological types were identified: an S-morph with stamen filaments longer than gynoecia, stigmas with a ...

Heterostyly accelerates diversification via reduced extinction in primroses [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 The exceptional species diversity of flowering plants, exceeding that of their sister group more than 250-fold, is especially evident in floral innovations, interactions with pollinators and sexual systems.

Phylogeographic insights on the evolutionary breakdown of heterostyly [PDF]
New Phytologist, 2017 Summary The breakdown of heterostyly to homostyly is a classic system for the investigation of evolutionary transitions from outcrossing to selfing. Loss of sexual polymorphism is characterized by changes to population morph structure and floral morphology.

Origin and diversification of flax and their relationship with heterostyly across the range [PDF]
Journal of Biogeography, 2021 Understanding plant diversity and how different traits have shaped the current biodiversity setting across the world is one of the major challenges for evolutionary biology.

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.

‘A most complex marriage arrangement’: recent advances on heterostyly and unresolved questions
New Phytologist, 2019 Heterostylous genetic polymorphisms provide paradigmatic systems for investigating adaptation and natural selection. Populations are usually comprised of two (distyly) or three (tristyly) mating types, maintained by negative frequency-dependent selection

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 ...
