Characterisation of genome-wide association epistasis signals for serum uric acid in human population isolates.

open access: yesPLoS ONE, 2011
Genome-wide association (GWA) studies have identified a number of loci underlying variation in human serum uric acid (SUA) levels with the SLC2A9 gene having the largest effect identified so far.

Epistasis and Shapes of Fitness Landscapes [PDF]

open access: yes, 2006
The relationship between the shape of a fitness landscape and the underlying gene interactions, or epistasis, has been extensively studied in the two-locus case. Gene interactions among multiple loci are usually reduced to two-way interactions.

Properties of selected mutations and genotypic landscapes under Fisher's Geometric Model

open access: yes, 2014
The fitness landscape - the mapping between genotypes and fitness - determines properties of the process of adaptation. Several small genetic fitness landscapes have recently been built by selecting a handful of beneficial mutations and measuring fitness

Higher-order epistasis and phenotypic prediction

open access: yesbioRxiv, 2020
Contemporary high-throughput mutagenesis experiments are providing an increasingly detailed view of the complex patterns of genetic interaction that occur between multiple mutations within a single protein or regulatory element.

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Epistasis detectably alters correlations between genomic sites in a narrow parameter window.

open access: yesPLoS ONE, 2019
Different genomic sites evolve inter-dependently due to the combined action of epistasis, defined as a non-multiplicative contribution of alleles at different loci to genome fitness, and the physical linkage of different loci in genome.

Fitness ranking of individual mutants drives patterns of epistatic interactions in HIV-1. [PDF]

open access: yesPLoS ONE, 2011
Fitness interactions between mutations, referred to as epistasis, can strongly impact evolution. For RNA viruses and retroviruses with their high mutation rates, epistasis may be particularly important to overcome fitness losses due to the accumulation ...

Statistical Physics of Evolutionary Trajectories on Fitness Landscapes [PDF]

open access: yes, 2013
Random walks on multidimensional nonlinear landscapes are of interest in many areas of science and engineering. In particular, properties of adaptive trajectories on fitness landscapes determine population fates and thus play a central role in ...

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.
