Brassinosteroid and jasmonic acid pathways mediate the effect of high temperature on the outcrossing rate of photo-thermo-sensitive genic male-sterile rice lines [PDF]

open access: yesBMC Plant Biology
Background The development and widespread adoption of hybrid rice have significantly contributed to global food security. However, the relatively high cost of hybrid seeds remains a limiting factor for its broader application.

Effects of Ploidy on Relationship Between Outbreeding Response and Fitness in a Plant Selfing Species [PDF]

open access: yesEcology and Evolution
Outbreeding 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.)

open access: yesAgronomy, 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

open access: yesEcology 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.

The Integral Role of Genetic Variation in the Evolution of Outcrossing in the Caenorhabditis elegans-Serratia marcescens Host-Parasite System. [PDF]

open access: yesPLoS ONE, 2016
Outcrossing is predicted to facilitate more rapid adaptation than self-fertilization as a result of genetic exchange between genetically variable individuals.

Mutation accumulation in a selfing population: consequences of different mutation rates between selfers and outcrossers. [PDF]

open access: yesPLoS 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.

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

open access: yesEpigenetics, 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

open access: yesJournal 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 ...

Gene expression drives the evolution of dominance. [PDF]

open access: yes, 2018
Dominance is a fundamental concept in molecular genetics and has implications for understanding patterns of genetic variation, evolution, and complex traits.
