Molecular polymorphisms that underlie trait variation in crops: Lessons learned from soybean

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Genetic variation within a germplasm is important in crop improvement, providing a foundation for breeders to develop new varieties. Traits of agronomic and economic importance are often mapped to identify the genetic basis of observed phenotypes, oftentimes using quantitative trait locus (QTL) analysis.

Genomic selection of root‐knot nematode (Meloidogyne enterolobii) resistance in watermelon wild relatives (Citrullus amarus)

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Meloidogyne enterolobii is a virulent root‐knot nematode (RKN) species posing a significant threat to watermelon production across the United States. The USDA, ARS, Plant Introduction (PI) collection of Citrullus amarus, a wild relative of cultivated watermelon (Citrullus lanatus), contains RKN‐resistance. However, incorporating RKN resistance

Using genomic selection to examine subgenome dominance and epistasis in allopolyploid strawberry

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Allopolyploids are organisms that possess multiple sets of chromosomes derived from distinct ancestral species, resulting in multiple subgenomes. Many important crops are allopolyploid, including wheat (Triticum aestivum), cotton (Gossypium hirsutum), coffee (Coffea arabica), and strawberry (Fragaria × ananassa).

Performance analysis of novel methods for detecting epistasis

BMC Bioinformatics, 2011
Background Epistasis is recognized fundamentally important for understanding the mechanism of disease-causing genetic variation. Though many novel methods for detecting epistasis have been proposed, few studies focus on their comparison.

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

Journal of Animal Ecology, Volume 95, Issue 3, Page 418-429, March 2026.
The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age‐at‐maturity, are correlated at an adaptive genomic hotspot, but through distinct genetic markers (SNPs), ruling out causality.

Testing the Domino Theory of Gene Loss in Buchnera aphidicola: The Relevance of Epistatic Interactions

Life, 2018
The domino theory of gene loss states that when some particular gene loses its function and cripples a cellular function, selection will relax in all functionally related genes, which may allow for the non-functionalization and loss of these genes.

Causes and consequences of bacterial local adaptation via MGEs in the plant microbiome

New Phytologist, Volume 249, Issue 5, Page 2215-2223, March 2026.
Summary Adaptations that enable plant‐associated bacteria to fill disparate niches comprise a critical component of microbial diversity. Genes that confer locally adaptive bacterial traits, ranging from heavy metal resistance to pathogen or symbiont infectivity, often reside within mobile genetic elements (MGEs) that can move between genomes.

SimHOEPI: A resampling simulator for generating single nucleotide polymorphism data with a high‐order epistasis model

Quantitative Biology
Epistasis is a ubiquitous phenomenon in genetics, and is considered to be one of main factors in current efforts to unveil missing heritability of complex diseases.

Novel methods for epistasis detection in genome-wide association studies.

PLoS ONE, 2020
More and more genome-wide association studies are being designed to uncover the full genetic basis of common diseases. Nonetheless, the resulting loci are often insufficient to fully recover the observed heritability. Epistasis, or gene-gene interaction,
