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

open access: yesFrontiers 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 ...

Phylogeographic insights on the evolutionary breakdown of heterostyly [PDF]

open access: yesNew 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.

Heterostyly in Goniolimon italicum (Plumbaginaceae), endemic to Abruzzo (central Apennines, Italy)

open access: yesAnales 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 ...

Functional Heterostyly in Tylosema esculentum (Caesalpinioideae) [PDF]

open access: yesAnnals of Botany, 2002
Tylosema esculentum is a long-lived perennial species endemic to arid areas of southern Africa. Its potential as a crop species has long been recognized as a result of the high oil and protein content of its seeds. The reproductive biology and breeding systems of the species were investigated in wild and experimental populations growing in Botswana ...

The S-Gene YUC6 Pleiotropically Determines Male Mating Type and Pollen Size in Heterostylous Turnera (Passifloraceae): A Novel Neofunctionalization of the YUCCA Gene Family [PDF]

open access: yesPlants, 2022
In heterostylous, self-incompatible Turnera species, a member of the YUCCA gene family, YUC6, resides at the S-locus and has been hypothesized to determine the male mating type.

Is heterostyly rare on oceanic islands? [PDF]

open access: yesAoB PLANTS, 2015
Heterostyly has been considered rare or absent on oceanic islands. However, there has been no comprehensive review on this issue. Is heterostyly truly rare on oceanic islands? What makes heterostyly rare on such islands? To answer these questions, we review the reproductive studies on heterostyly on oceanic islands, with special emphasis on the ...

Comprehensive transcriptomic profiling reveals complex molecular mechanisms in the regulation of style-length dimorphism in Guettarda speciosa (Rubiaceae), a species with “anomalous” distyly [PDF]

open access: yesFrontiers in Plant Science, 2023
BackgroundThe evolution of heterostyly, a genetically controlled floral polymorphism, has been a hotspot of research since the 19th century. In recent years, studies on the molecular mechanism of distyly (the most common form of heterostyly) revealed an ...

Asymmetrical disassortative pollination mediated by long‐/short‐tongued pollinators in a distylous Limonium myrianthum (Plumbaginaceae) with a short corolla tubular small flower [PDF]

open access: yesEcology and Evolution
In heterostylous plants, short‐tongued pollinators are often ineffective/inefficient owing to the limitations imposed by a long corolla tube. However, it is unclear how disassortative pollen transfer is achieved in small flowers.

The influence of heterostyly, pollination method and hormonization on eggplant's (Solanum melongena L.) flowering and fruiting

open access: yesActa Agrobotanica, 2013
The experiment was carried out in a three unheated plastic tunnels in 1998-2000. The aim of this study was to estimate the effects of flower's heterostyly and two methods of flower pollination (self-pollination and using bumble-bee) as well as flower ...
