Can ploidy changes propel the evolution of allogamy in a selfing species complex? [PDF]
BMC Plant BiologyBackground The transition to self-fertilization has occurred repeatedly across diverse plant groups, and the evolutionary consequences of selfing typically suggest that a shift toward outcrossing is unlikely.

Late-acting self-incompatible system, preferential allogamy and delayed selfing in the heteromorphic invasive populations of Ludwigia grandiflora subsp. hexapetala [PDF]
Peer Community Journal, 2022 Breeding system influences local population genetic structure, effective size, offspring fitness and functional variation. Determining the respective importance of self- and cross-fertilization in hermaphroditic flowering plants is thus important to ...

Iterative allogamy–autogamy transitions drive actual and incipient speciation during the ongoing evolutionary radiation within the orchid genus Epipactis (Orchidaceae) [PDF]
Annals of Botany, 2019 AbstractBackground and AimsThe terrestrial orchid genus Epipactis has become a model system for the study of speciation via transitions from allogamy to autogamy, but close phylogenetic relationships have proven difficult to resolve through Sanger sequencing.MethodsWe analysed with restriction site-associated sequencing (RAD-seq) 108 plants ...

Allogamy-Autogamy Switch Enhance Assortative Mating in the Allotetraploid Centaurea seridis L. Coexisting with the Diploid Centaurea aspera L. and Triggers the Asymmetrical Formation of Triploid Hybrids [PDF]
PLoS ONE, 2015 Hybridization between tetraploids and their related diploids is generally unsuccessful in Centaurea, hence natural formation of triploid hybrids is rare. In contrast, the diploid Centaurea aspera and the allotetraploid C.

Reproductive Biology of the Two Varieties of Anacyclus pyrethrum L.—Anacyclus pyrethrum var. pyrethrum (L.) Link and Anacyclus pyrethrum var. depressus (Ball.) Maire—An Endemic Endangered Species [PDF]
Plants, 2022 The reproductive system is essential for the structuring and transmission of genetic diversity. Understanding the reproductive biology of threatened endemic species is considered to be a crucial element for the implementation of effective conservation ...

Separated Sexes, Shared Consequences: Disentangling Predictors of Genetic Diversity in Dioecious Angiosperms. [PDF]
Ecol EvolThis study evaluates the factors influencing intrapopulation genetic diversity in dioecious flowering plants by integrating genetic and ecological data from studies published up to 2025. We show that pollination mode, endemism, and conservation status significantly shape genetic diversity patterns, with endemic and threatened species exhibiting the ...

Floral Traits, Pollination and Reproductive Differentiation in Gynodioecious Minuartia nifensis (Caryophyllaceae) [PDF]
PlantsThe endemic Minuartia nifensis, the only known gynodioecious species of its genus, offers a suitable model for understanding the relationships between floral characteristics, pollination, and mating systems in species with narrow distributions and single

Silene, a versatile model system: from sex and genome evolution to ecology and speciation. [PDF]
New PhytolSummary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Allogamy, metaxenia and hybrids in orchids, what do we know about it?
Botanical SciencesOrchids are a diverse group of plants, also manifested in their great diversity of flowers. Despite this, orchids are pollinated either through autogamy or allogamy (geitonogamy and xenogamy). Although there are some autogamous orchids, the majority are
