Weakest link epistasis and the geometry of genetic load

Abstract Because natural selection must optimise multiple traits at once, previous work has suggested that phenotypic dimensionality can substantially worsen the equilibrium fitness defect of a population relative to the phenotypic optimum.

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.

Reducing Epistasis and Pleiotropy Can Avoid the Survival of the Flattest Tragedy

Biology
This study investigates whether reducing epistasis and pleiotropy enhances mutational robustness in evolutionary adaptation, utilizing an indirect encoded model within the “survival of the flattest” (SoF) fitness landscape.

Genome‐wide association studies for identifying SNPs and candidate genes associated with grain quality traits in rice (Oryza sativa L.)

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Ensuring superior quality is of paramount objective in modern rice (Oryza sativa L.) breeding program and investigating quality traits is crucial for developing superior rice varieties. The current study aimed for identifying single nucleotide polymorphisms (SNPs) and potential candidate genes for eleven quality traits, namely, hulling ...

Identification of resistance sources and genomic regions regulating spot blotch resistance in Asian bread wheat (Triticum aestivum L.) via genome‐wide association study

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Spot blotch (SB), caused by Bipolaris sorokiniana, is a major yield‐limiting disease of wheat (Triticum aestivum L.) in the warm, humid agroclimatic zones of South Asia. The development of resistant cultivars through molecular approaches offers a sustainable strategy for managing this disease.

Allele‐informed QTL‐seq identifies Hd18 as a minor modifier of heading date in elite rice cultivars

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Fine‐tuning heading date is critical for optimizing yield, grain quality, and local adaptation in rice (Oryza sativa L.). QTL‐seq (where QTL is quantitative trait locus), which integrates bulked segregant analysis with whole‐genome resequencing, provides a rapid and cost‐effective approach for identifying QTLs underlying complex traits ...

Distributed transformer for high order epistasis detection in large-scale datasets

Scientific Reports
Understanding the genetic basis of complex diseases is one of the most important challenges in current precision medicine. To this end, Genome-Wide Association Studies aim to correlate Single Nucleotide Polymorphisms (SNPs) to the presence or absence of ...

GWAS and genomic prediction of crown rust resistance in the southern US elite oat (Avena sativa L.) germplasm

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Crown rust (CR), caused by Puccinia coronata f. sp. avenae, is a major constraint to oat (Avena sativa L.) production in the southern United States. We dissected the genetic architecture of CR resistance and assessed genomic prediction in 234 winter and facultative oat lines adapted to the southern United States.
