Proceedings of the Royal Society B: Biological Sciences, 2011 Since Bateson's discovery that genes can suppress the phenotypic effects of other genes, gene interactions—called epistasis—have been the topic of a vast research effort. Systems and developmental biologists study epistasis to understand the genotype–phenotype map, whereas evolutionary biologists recognize the fundamental importance of epistasis for ...

The power of many: when genetics met yeasts and high‐throughput
Biological Reviews, EarlyView.ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Sign epistasis caused by hierarchy within signalling cascades
Nature Communications, 2018 Sign epistasis clearly constrains evolution, but its causes are difficult to decipher. Here, the authors study epistasis in a signalling cascade, and arrive at a general criterion and understanding of sign epistasis as arising from the inherent hierarchy

PLANTS, PEOPLE, PLANET, EarlyView.Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

The consistency of beneficial fitness effects of mutations across diverse genetic backgrounds. [PDF]
PLoS ONE, 2012 Parallel and convergent evolution have been remarkably common observations in molecular adaptation but primarily in the context of the same genotype adapting to the same conditions.

The nk model and population genetics [PDF]
, 2005 The nk model of fitness interactions is examined. This model has been used by previous authors to investigate the effects of fitness epistasis on substitution dynamics in molecular evolution, and to make broader claims about the importance of epistasis ...

PLANTS, PEOPLE, PLANET, EarlyView.Field inoculation with arbuscular mycorrhizal fungi (AMF) offers a promising route to improve sustainable agriculture and food production, yet results are often variable. We investigated the mycorrhizal growth response of maize and wheat varieties recommended for farmers and found substantial variation under greenhouse conditions.

Effects of Epistasis and Pleiotropy on Fitness Landscapes
, 2013 The factors that influence genetic architecture shape the structure of the fitness landscape, and therefore play a large role in the evolutionary dynamics. Here the NK model is used to investigate how epistasis and pleiotropy -- key components of genetic

Statistical Modeling of Epistasis and Linkage Decay using Logic Regression [PDF]
, 2008 Logic regression has been recognized as a tool that can identify and model non-additive genetic interactions using Boolean logic groups. Logic regression, TASSEL-GLM and SAS-GLM were compared for analytical precision using a previously characterized ...

Data reconciliation in multi‐trait experiments with kinship ordination
Methods in Ecology and Evolution, EarlyView.Abstract A central aim in biology is understanding the heritability of traits and how trait interactions contribute to success in diverse environments. Experiments that record multiple traits from individuals of known pedigree or genetic relatedness in distinct environments are key to addressing this aim.
