Evolution of fertilization ability in obligatorily outcrossing populations of Caenorhabditis elegans [PDF]

PeerJ, 2023
In species reproducing by selfing, the traits connected with outcrossing typically undergo degeneration, a phenomenon called selfing syndrome. In Caenorhabditis elegans nematodes, selfing syndrome affects many traits involved in mating, rendering cross ...

Phenotypic Selection in Halenia elliptica D. Don (Gentianaceae), an Alpine Biennial with Mixed Mating System

Plants, 2022
The transition from outcrossing to selfing is a common evolutionary trend in flowering plants, and floral traits change significantly with the evolution of selfing.

No detectable changes in reproductive behaviour of Caenorhabditis elegans males after 97 generations under obligatory outcrossing [PDF]

PeerJ, 2023
In Caenorhabditis elegans, a species reproducing mostly via self-fertilization, numerous signatures of selfing syndrome are observed, including differences in reproductive behaviour compared to related obligatory outcrossing species.

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 ...

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.

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.

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 ...

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 ...
