Domestication During Restoration: Unintentional Selection During Eight Generations of Wild Seed Propagation Reduces Herkogamy, Dichogamy and Heterozygosity in Clarkia pulchella

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these ...

Avoiding sexual interference: herkogamy and dichogamy in style dimorphic flowers of Narcissus broussonetii (Amaryllidaceae) [PDF]

open access: yes, 2019
Spatial (herkogamy) or temporal (dichogamy) separation of sex organs are mechanisms considered to restrict self-pollination and promote outcrossing. Additionally, avoidance of self-interference is proposed to be the driving force for the evolution of ...

Biologia reprodutiva de Rourea induta Planch. (Connaraceae), uma espécie heterostílica de cerrado do Brasil Central. [PDF]

open access: yes, 2017
(Biologia reprodutiva de Rourea induta Planch. (Connaraceae), uma espécie heterostílica de cerrado do Brasil Central). A heterostilia é um polimorfismo floral geralmente associado a sistemas genéticos de intramorfo incompatibilidade.

Genome size, morphological and palynological variations, and heterostyly in some species of the genus Linum L. (Linaceae) in Iran [PDF]

open access: yes, 2016
Heterostyly is the occurrence of flowers with different sexual organ arrangements in different plants of the same species. This floral polymorphism occurs in four sections of genus Linum.

Characterization of 24 microsatellite markers in Primula chungensis (Primulaceae), a distylous–homostylous species, using MiSeq sequencing

open access: yesPlant Diversity, 2016
Primula chungensis is a species with considerable floral and mating-system variation, including distylous (outcrossing), homostylous (selfing) and mixed populations that contain both outcrossing and selfing forms.

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Studies on Incompatibility Pollination and Floral Morphological Polymorphism of Carambola (Averrhoa Corambola L) [PDF]

open access: yes, 1998
The objectives of this study were to elucidate the physiological basis of selfincompatibility system and the floral morphological polymorphism in carambola (Averrhoa carambola L.). Within 30 minutes after pollination, pollen degradation and hydration

Atypical distyly in Psychotria goyazensis Mull. Arg. (Rubiaceae), an intramorph self-compatible species

open access: yesActa 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).

Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids [PDF]

open access: yes
Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Rapid detection of RNase‐based self‐incompatibility in Lysimachia monelli (Primulaceae)

open access: yesAmerican Journal of Botany, Volume 112, Issue 1, January 2025.
Abstract Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.
