Multidimensional Epistasis and the Advantage of Sex

, 2005
Kondrashov and Kondrashov (2001) suggest that there is usually a disadvantage for sex in systems with multidimensional epistasis. They define systems of 'unidimensional epistasis' to be those where the fitness of a genotype is a function of the number of

Exact Results for Amplitude Spectra of Fitness Landscapes

, 2013
Starting from fitness correlation functions, we calculate exact expressions for the amplitude spectra of fitness landscapes as defined by P.F. Stadler [J. Math. Chem.

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 ...

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.

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

The MdICE1/MdFAMA‐MdTYDC Transcriptional Module Confers Cold Tolerance by Regulating Dopamine Metabolism in Apple

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3012-3031, May 2026.
ABSTRACT Low temperature is a critical abiotic stress that imposes major constraints on the sustainable development of the fruit tree industry. Although exogenous dopamine has been shown to enhance cold tolerance in plants, its molecular mechanisms in apple (Malus domestica) remain poorly understood.

Natural Negative Feedback Loops Confer Indica‐Japonica Differentiation for Grain Size Homeostasis in Rice

Advanced Science, Volume 13, Issue 19, 2 April 2026.
This study reveals the genetic and molecular mechanisms controlling grain size homeostasis through fine‐tuning OsGRX8 self‐expression by two natural negative feedback loops functioning in redox‐dependent or ‐independent manners and identifies two self‐regulatory haplotypes (SRHs) for the subspecies differentiation in rice.

Universality classes of interaction structures for NK fitness landscapes

, 2018
Kauffman's NK-model is a paradigmatic example of a class of stochastic models of genotypic fitness landscapes that aim to capture generic features of epistatic interactions in multilocus systems. Genotypes are represented as sequences of $L$ binary loci.

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

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.
