Population size as a major determinant of mating system and population genetic differentiation in a narrow endemic chasmophyte

BMC Plant Biology, 2023
Background Mating system is one of the major determinants of intra- and interspecific genetic structure, but may vary within and between plant populations.

New genomic resources and comparative analyses reveal differences in floral gene expression in selfing and outcrossing Collinsia sister species

G3: Genes, Genomes, Genetics, 2021
The evolutionary transition from outcross- to self-fertilization is one of the most common in angiosperms and is often associated with a parallel shift in floral morphological and developmental traits, such as reduced flower size and pollen to ovule ...

Self‐correction prevents withdrawal syndrome [PDF]

The EMBO Journal, 2019
The scientific research paper remains the primary mode for documenting scholarly achievement in a stable, citable manner, yet the toolkit that allows for changes and corrections to research papers limits the optimal dissemination of reliable research findings.

Evolution of Autonomous Selfing in Marginal Habitats: Spatiotemporal Variation in the Floral Traits of the Distylous Primula wannanensis

Frontiers in Plant Science, 2021
Outcrossing plant species are more likely to exhibit autonomous selfing in marginal habitats to ensure reproduction under conditions of limited pollinator and/or mate availability.

A Self-Care Deficiency Syndrome: Self-Neglect

Psikiyatride Güncel Yaklaşımlar, 2023
Self-neglect is the individual's failure to show the necessary attention and care in his own care. Self-neglect manifests itself as non-adherence to treatment, failure to maintain personal and environmental hygiene, and maladaptive health behaviours. At the global level, although self-neglect is frequently seen especially in the elderly population, it ...

Mating behavior and reproductive morphology predict macroevolution of sex allocation in hermaphroditic flatworms

BMC Biology, 2022
Background Sex allocation is the distribution of resources to male or female reproduction. In hermaphrodites, this concerns an individual’s resource allocation to, for example, the production of male or female gametes.

Population Genomics of the “Arcanum” Species Group in Wild Tomatoes: Evidence for Separate Origins of Two Self-Compatible Lineages

Frontiers in Plant Science, 2021
Given their diverse mating systems and recent divergence, wild tomatoes (Solanum section Lycopersicon) have become an attractive model system to study ecological divergence, the build-up of reproductive barriers, and the causes and consequences of the ...

The divergence history of the perennial plant Linaria cavanillesii confirms a recent loss of self-incompatibility. [PDF]

, 2017
Many angiosperms prevent inbreeding through a self-incompatibility (SI) system, but the loss of SI has been frequent in their evolutionary history.

Ginger and the beetle: Evidence of primitive pollination system in a Himalayan endemic alpine ginger (Roscoea alpina, Zingiberaceae). [PDF]

PLoS ONE, 2017
The Himalayan endemic alpine genus Roscoea, like other members of ginger family, exhibits the combination of floral traits that would fit pollination by long distant foragers such as bees, birds or flies.

Long-term balancing selection drives evolution of immunity genes in Capsella. [PDF]

, 2019
Genetic drift is expected to remove polymorphism from populations over long periods of time, with the rate of polymorphism loss being accelerated when species experience strong reductions in population size.
