Environment-dependent epistasis increases phenotypic diversity in gene regulatory networks

Florence Gauye, Florian Baier

Mutations to gene regulatory networks can be maladaptive or a source of evolutionary novelty. Epistasis con-founds our understanding of how mutations affect the expression patterns of gene regulatory networks, a chal-lenge exacerbated by the dependence of ...

Spatial areas of genotype probability: Predicting the spatial distribution of adaptive genetic variants under future climatic conditions

Stéphane Joost, Estelle Rochat, Oliver Michele Selmoni

In a context of rapid global change, one of the key components for the survival of species is their genetic evolutionary potential for adaptation. Many methods have been developed to identify genetic variants underpinning adaptation to climate, but few too ...

The genetic architecture of complex human traits at the dawn of genomic medicine

Olivier Noël Marie Naret

The focus of the work presented in this thesis is the exploration of the genetic architecture of complex human traits - at the dawn of genomic medicine. The underlying mechanisms explaining the enormously polygenic nature of most human complex traits are ...

Direct coupling analysis of epistasis in allosteric materials

Matthieu Wyart, Riccardo Ravasio, Barbara Bravi

In allosteric proteins, the binding of a ligand modifies function at a distant active site. Such allosteric pathways can be used as target for drug design, generating considerable interest in inferring them from sequence alignment data. Currently, differen ...

Experimental adaptation of human echovirus 11 to ultraviolet radiation leads to tolerance to disinfection and resistance to ribavirin

Tamar Kohn, Jeffrey David Jensen, Anna Carratala Ripolles, Virginie Bachmann, Qingxia Zhong, Hyunjin Shim

Ultraviolet light in the UVC range is a commonly used disinfectant to control viruses in clinical settings and water treatment. Here, we employed an experimental evolution approach to investigate the adaptation of human echovirus 11 to disinfection by UVC, ...

Distinguishing knowledge integration gains in evolution education through concept map network analysis

Beat Adrian Schwendimann

Understanding how evolutionary changes happen requires connecting genotype and phenotype level concepts. This study uses a form of concept map, called Knowledge Integration Map (KIM), as a learning and assessment tool to support and assess connecting conce ...

Catch Me if You Can: Adaptation from Standing Genetic Variation to a Moving Phenotypic Optimum

Sebastian Matuszewski

Adaptation lies at the heart of Darwinian evolution. Accordingly, numerous studies have tried to provide a formal framework for the description of the adaptive process. Of these, two complementary modeling approaches have emerged: While so-called adaptive- ...

Genetic interplay between HLA-C and MIR148A in HIV control and Crohn disease

Jacques Fellay, Paul Jack Mc Laren

Variation in the 3' untranslated region (3'UTR) of the HLA-C locus determines binding of the microRNA Hsa-miR-148a, resulting in lower cell surface expression of alleles that bind miR-148a relative to those alleles that escape its binding. The HLA-C 3'UTR ...

The Limits to Parapatric Speciation: Dobzhansky-Muller Incompatibilities in a Continent-Island Model

Claudia Bank

How much gene flow is needed to inhibit speciation by the accumulation of Dobzhansky-Muller incompatibilities (DMIs) in a structured population? Here, we derive these limits in a classical migration-selection model with two haploid or diploid loci and unid ...

Perspectives on the use of landscape genetics to detect genetic adaptive variation in the field

Stéphane Joost

Understanding the genetic basis of species adaptation in the context of global change poses one of the greatest challenges of this century. Although we have begun to understand the molecular basis of adaptation in those species for which whole genome seque ...

Division of labour and colony efficiency in social insects: effects of interactions between genetic architecture, colony kin structure and rate of perturbations

Dario Floreano, Laurent Keller, Stéphane Magnenat, Markus Waibel

The efficiency of social insect colonies critically depends on their ability to efficiently allocate workers to the various tasks which need to be performed. While numerous models have investigated the mechanisms allowing an efficient colony response to ex ...
