Searching for interacting QTL in related populations of an outbreeding species [PDF]

, 2009
Many important crop species are outbreeding. In outbreeding species the search for genes affecting traits is complicated by the fact that in a single cross up to four alleles may be present at each locus.

Genomic prediction in Persian walnut: Optimization levers according to genetic architecture of complex traits

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Persian walnut (Juglans regia L.) is a widespread cultivated nut tree species in temperate regions. Advances in genomic tools, such as the high‐density Axiom J. regia 700K single nucleotide polymorphism (SNP) genotyping array, enable the exploration of genomic prediction (GP) for this crop.

Genomic selection: Essence, applications, and prospects

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Genomic selection (GS) emerged as a key part of the solution to ensure the food supply for the growing human population thanks to advances in genotyping and other enabling technologies and improved understanding of the genotype–phenotype relationship in quantitative genetics.

Epistasis and evolution: recent advances and an outlook for prediction

BMC Biology, 2023
As organisms evolve, the effects of mutations change as a result of epistatic interactions with other mutations accumulated along the line of descent. This can lead to shifts in adaptability or robustness that ultimately shape subsequent evolution. Here,

Studying the genetic basis of ecological interactions with intergenomic epistasis

Oikos, Volume 2025, Issue 6, June 2025.
In a community, the phenotype or fitness of genotypes of a focal species can depend on the genotypes of other species. Such between‐species genetic interactions are increasingly referred to as intergenomic epistasis, analogous to the classical definition of (intragenomic) epistasis in genetics.

Generalized Walsh Transforms and Epistasis [PDF]

Bulletin of the Belgian Mathematical Society - Simon Stevin, 2006
In this note, we introduce and briefly study a non-binary analogue of the “classical” Walsh transform. It is shown that this transform allows to rewrite the definition of normalized epistasis in terms of generalized Walsh coecients, in a way which is both practical and elegant.

Interaction models matter: an efficient, flexible computational framework for model-specific investigation of epistasis

BioData Mining
Purpose Epistasis, the interaction between two or more genes, is integral to the study of genetics and is present throughout nature. Yet, it is seldom fully explored as most approaches primarily focus on single-locus effects, partly because analyzing all

Influence of epistasis on response to genomic selection using complete sequence data

Genetics Selection Evolution, 2017
Background The effect of epistasis on response to selection is a highly debated topic. Here, we investigated the impact of epistasis on response to sequence-based selection via genomic best linear prediction (GBLUP) in a regime of strong non-symmetrical ...

Association mapping for epistasis and environmental interaction of yield traits in 323 cotton cultivars under 9 different environments. [PDF]

PLoS ONE, 2014
Improving yield is a major objective for cotton breeding schemes, and lint yield and its three component traits (boll number, boll weight and lint percentage) are complex traits controlled by multiple genes and various environments.

Evolutionary interplay between structure, energy and epistasis in the coat protein of the $φχ174$ phage family [PDF]

arXiv, 2015
Viral capsids are structurally constrained by interactions amongst the amino acids of the constituting proteins. Therefore, epistasis is expected to evolve amongst sites engaged in physical interactions, and to influence their substitution rates. In order to study the distribution of structural epistasis, we modeled \emph{in silico} the capsid of 18 ...
