The Integral Role of Genetic Variation in the Evolution of Outcrossing in the Caenorhabditis elegans-Serratia marcescens Host-Parasite System. [PDF]
PLoS ONE, 2016 Outcrossing is predicted to facilitate more rapid adaptation than self-fertilization as a result of genetic exchange between genetically variable individuals.

Effects of Ploidy on Relationship Between Outbreeding Response and Fitness in a Plant Selfing Species [PDF]
Ecology and EvolutionOutbreeding response, the phenotypic differences observed between selfed parental lines and their outcrossed offspring, can influence the evolution of selfing strategies. However, such effects remain poorly understood in noncrop species.

Frequency of Outcrossing and Isolation Distance in Faba Beans (Vicia faba L.)
Agronomy, 2023 Faba beans (Vicia faba L.) constitute a partially outcrossing species requiring an isolation distance to maintain genetic purity when more than one variety is grown in field conditions. This information is crucial for seed growers and faba bean breeders.

Influence of plant reproductive systems on the evolution of hummingbird pollination
Ecology and Evolution, 2022 Many hummingbird‐pollinated plant species evolved from bee‐pollinated ancestors independently in many different habitats in North and South America. The mechanisms leading to these transitions are not completely understood.

Mutation accumulation in a selfing population: consequences of different mutation rates between selfers and outcrossers. [PDF]
PLoS ONE, 2012 Currently existing theories predict that because deleterious mutations accumulate at a higher rate, selfing populations suffer from more intense genetic degradation relative to outcrossing populations.

Why outcross? The abandon-ship hypothesis in a facultative outcrossing/selfing fungal species [PDF]
Fungal Genetics and Biology, 2018 Most species able to reproduce both sexually and asexually (facultative sexual species) invest more in sexual reproduction in stressful environment conditions. According to the abandon-ship hypothesis, plasticity for investment in sexual reproduction may have been selected in these species, allowing unfit genotypes to generate progeny carrying new ...

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 ...

Genetic effects and plant architecture influences on outcrossing rate in soybean
Journal of Integrative Agriculture, 2019 Outcrossing rate is an important determinant of cytoplasmic male sterile (CMS) breeding and hybrid seed production for heterosis in soybean. Parental lines with a high outcrossing rate were screened for backcross breeding to obtain the high outcrossing ...
