Preventing self-fertilization: Insights from Ziziphus species [PDF]

Frontiers in Plant Science, 2023
The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Evolutionary consequences of self-fertilization in plants. [PDF]

Proc Biol Sci, 2013
The transition from outcrossing to self-fertilization is one of the most common evolutionary changes in plants, yet only about 10–15% of flowering plants are predominantly selfing. To explain this phenomenon, Stebbins proposed that selfing may be an ‘evolutionary dead end’.

Mating suppresses sperm-dependent male avoidance in C. elegans hermaphrodites. [PDF]

PLoS ONE
In many sexually reproducing animals, females incur higher reproductive costs and therefore tend to be more selective in accepting mates. In Caenorhabditis elegans, self-fertilizing hermaphrodites produce a limited number of self-sperm, and previous ...

Developmental plasticity of hermaphrodite sperm production across environments in Caenorhabditis elegans. [PDF]

PLoS ONE
Many organisms show flexible resource allocation to adjust for optimal reproductive investment across different environments. How such reproductive plasticity occurs in hermaphroditic organisms-allocating resources to both oocytes and sperm-are central ...

A Semi-Automated SNP-Based Approach for Contaminant Identification in Biparental Polyploid Populations of Tropical Forage Grasses

Frontiers in Plant Science, 2021
Artificial hybridization plays a fundamental role in plant breeding programs since it generates new genotypic combinations that can result in desirable phenotypes.

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 ...

Comparing levels of geitonogamous visitation by honey bees and other pollinators

Journal of Pollination Ecology, 2023
Geitonogamy, the transfer of pollen from one flower to another on the same plant, is often the primary means of self-pollination in flowering plants.

Additive and non-additive epigenetic signatures of natural hybridization between fish species with different mating systems

Epigenetics, 2022
Hybridization is a major source of evolutionary innovation. In plants, epigenetic mechanisms can help to stabilize hybrid genomes and contribute to reproductive isolation, but the relationship between genetic and epigenetic changes in animal hybrids is ...

Balancing selection in self‐fertilizing populations [PDF]

Evolution, 2021
Self-fertilization commonly occurs in hermaphroditic species, either occasionally or as the main reproductive mode. It strongly affects the genetic functioning of a population by increasing homozygosity and genetic drift and reducing the effectiveness of recombination.
