Can ploidy changes propel the evolution of allogamy in a selfing species complex? [PDF]

BMC Plant Biology
Background 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.

Separated Sexes, Shared Consequences: Disentangling Predictors of Genetic Diversity in Dioecious Angiosperms [PDF]

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This 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 ...

Allogamy, metaxenia and hybrids in orchids, what do we know about it?

Botan‪ical Sciences
Orchids 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

Floral Traits, Pollination and Reproductive Differentiation in Gynodioecious Minuartia nifensis (Caryophyllaceae) [PDF]

Plants
The 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

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna [PDF]

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation [PDF]

New Phytologist, Volume 250, Issue 6, Page 3613-3630, June 2026.
Summary 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 ...

Effect of Simulated Autogamy and Allogamy on the Success of Cephalanthera longifolia and Cephalanthera rubra (Orchidaceae) Fruit Set

Diversity
Detailed knowledge of reproductive traits and success is essential for the effective conservation of rare and endangered species. It has been reported that Cephalanthera longifolia and C.

Floral and pollination biology of dragon fruit reveals strategies for enhancing productivity through pollination management and reproductive window extension [PDF]

Scientific Reports
Dragon fruit (Selenicereus undatus (Haw.) D.R. Hunt) is emerging as a high-value crop globally. However, its reproductive biology remains poorly characterized, with conflicting reports ranging from strict self-incompatibility (allogamy) to self ...

Seed germination and seedling allogamy inRosmarinus officinalis: the costs of inbreeding [PDF]

Plant Biology, 2018
AbstractSelf‐pollination by geitonogamy is likely in self‐compatible plants that simultaneously expose a large number of flowers to pollinators. However, progeny of these plants is often highly allogamous. Although mechanisms to increase cross‐pollination have been identified and studied, their relative importance has rarely been addressed ...
