Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]

open access: yes, 2020
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Multifactorial methods integrating haplotype and epistasis effects for genomic estimation and prediction of quantitative traits

open access: yesFrontiers in Genetics, 2022
The rapid growth in genomic selection data provides unprecedented opportunities to discover and utilize complex genetic effects for improving phenotypes, but the methodology is lacking. Epistasis effects are interaction effects, and haplotype effects may

Epistasis shapes the fitness landscape of an allosteric specificity switch

open access: yesNature Communications, 2021
Epistasis plays an important role in the evolution of novel protein functions because it determines the mutational path a protein takes. Here, the authors combine functional, structural and biophysical analyses to characterize epistasis in a ...

Hidden epistastic interactions can favour the evolution of sex and recombination. [PDF]

open access: yesPLoS ONE, 2012
Deleterious mutations can have a strong influence on the outcome of evolution. The nature of this influence depends on how mutations combine together to affect fitness.

Stability-mediated epistasis constrains the evolution of an influenza protein. [PDF]

open access: yes, 2013
John Maynard Smith compared protein evolution to the game where one word is converted into another a single letter at a time, with the constraint that all intermediates are words: WORD→WORE→GORE→GONE→GENE. In this analogy, epistasis constrains evolution,

Whole genome sequencing reveals epistasis effects within RET for Hirschsprung disease

open access: yesScientific Reports, 2022
Common variants in RET and NRG1 have been associated with Hirschsprung disease (HSCR), a congenital disorder characterised by incomplete innervation of distal gut, in East Asian (EA) populations.

Competition between recombination and epistasis can cause a transition from allele to genotype selection [PDF]

open access: yes, 2009
Biochemical and regulatory interactions central to biological networks are expected to cause extensive genetic interactions or epistasis affecting the heritability of complex traits and the distribution of genotypes in populations. However, the inference

Parallel and serial computing tools for testing single-locus and epistatic SNP effects of quantitative traits in genome-wide association studies

open access: yesBMC Bioinformatics, 2008
Background Genome-wide association studies (GWAS) using single nucleotide polymorphism (SNP) markers provide opportunities to detect epistatic SNPs associated with quantitative traits and to detect the exact mode of an epistasis effect.

Two-stage genome-wide search for epistasis with implementation to Recombinant Inbred Lines (RIL) populations. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVE AND METHODS:This paper proposes an inegrative two-stage genome-wide search for pairwise epistasis on expression quantitative trait loci (eQTL).

Dynamic network-based epistasis analysis: Boolean examples

open access: yesFrontiers in Plant Science, 2011
In this review we focus on how the hierarchical and single-path assumptions of epistasis analysis can bias the topologies of gene interactions infered. This has been acknowledged in several previous papers and reviews, but here we emphasize the critical ...
