In this thesis, we present several algorithmic results for problems in spectral graph theory and computational biology. The first part concerns the problem of spectral sparsification. It is known that every dense graph can be approximated in a strong sense by a sparse subgraph, known as a spectral sparsifier of the graph. Furthermore, researchers have recently developed efficient algorithms for computing such approximations. We show how to make these algorithms faster, and also give a substantial improvement in space efficiency. Since sparsification is an important first step in speeding up approximation algorithms for many graph problems, our results have numerous applications. In the second part of the thesis, we consider the problem of inferring human population history from genetic data. We give an efficient and principled algorithm for using single nucleotide polymorphism (SNP) data to infer admixture history of various populations, and apply it to show that Europeans have evidence of mixture with ancient Siberians. Finally, we turn to the problem of RNA secondary structure design. In this problem, we want to find RNA sequences that fold to a given secondary structure. We propose a novel global sampling approach, based on the recently developed RNAmutants algorithm, and show that it has numerous desirable properties when compared to existing solutions. Our method can prove useful for developing the next generation of RNA design algorithms.

In Angiosperms, there exists a strong association between life-history and mating system. Indeed, most predominantly selfing species are annual while the majority of perennials are outcrossers. This association is the starting point of the work presented in this thesis. In the first chapter, I study the joint evolution of lifespan and selfing assuming that inbreeding depression affects survival between flowering seasons and is fixed by a parameter. Under these assumptions, lifetime inbreeding depression increases as lifespan increases therefore preventing the evolution of self-fertilisation in a wider parameter range. When it occurs, it induces the evolution of shorter lifespans. These results are in agreement with the empirically observed pattern. In chapter two, I relax the assumption that inbreeding depression is fixed by a parameter, by assuming an explicit genetic basis. Far from generating higher inbreeding depression in more long-lived species, deleterious mutations affecting survival result in a decrease of inbreeding depression with longevity at mutation-selection equilibrium. Yet, increased inbreeding depression is empirically observed in long-lived species. In the following chapters, I explore two hypotheses to explain this increase. In chapter two, I study the more general idea that variations in the fitness effects of mutations with longevity, of which mutations affecting survival are a mere special case, may generate increased inbreeding depression in longer-lived species. In chapter three, I model the consequences of inheritable somatic mutations accumulating during growth for the evolution of the mutation rate and the resulting inbreeding depression in plants. As for chapter four, it is devoted to a theoretical evaluation of indirect inbreeding depression estimation methods. I end this manuscrit by proposing leads and ideas for the development of a physiological and genetic theory of plant evolution

Sporophytic self-incompatibility is a genetic system preventing self-fertilization by self-recognition. In many species, this system is controlled by a single locus, the S-locus, composed of two linked genes coding for the pistil and pollen recognition proteins. The self-incompatibility locus is a classical case of a particular form of balancing selection called negative frequency dependent selection. This form of selection is predicted to cause an accumulation of polymorphism in the flanking regions of the S-locus, including sheltered deleterious mutations. In the Brassicacea, this system exhibits a linear dominance hierarchy between S-alleles. This dominance network is controlled by interactions between small RNAs linked to dominant S-alleles and their target sequences on recessive alleles of the gene controlling the pollen specificities SCR. The dominance level is predicted to have an effect on the accumulation of polymorphisms in regions immediately linked to the S-locus, with a higher accumulation of the genetic load sheltered by dominant S-alleles than by recessive S-alleles.In my PhD project, I first studied the effect of balancing selection at the S-locus on polymorphism in the flanking regions in order to determine the magnitude of the peak of polymorphism and to characterize its molecular properties. I used whole genome resequencing data from several populations of A. halleri and A. lyrata to specifically determine the chromosomal distance up to which the effect of the S-locus can still be observed. I observed an increase of polymorphism in the first 25kb around the S-locus, mainly explained by an increase of the proportion of polymorphic sites.I then tested if dominance of the S-alleles influences the genetic load they accumulate. I combined a genomic approach using parent-offspring trios to phase haplotypes and compare the number of deleterious mutations linked to dominant vs. recessive S-alleles, with a phenotypic approach to experimentally measure the severity of the load. I demonstrated that dominance promotes contrasted profiles of the genetic load between the recessive and the dominant S-alleles.Finally, I used a modeling approach based on stochastic simulations to predict the evolution of the dominance network between S-alleles, taking interactions between small RNAs and their SCR targets explicitly into account. My results show that mutations have different fixation probabilities according to whether they occur on dominant vs. recessive S-alleles, and also whether they hit the small RNA producing locus or its target sites. The distribution of the sheltered genetic load between dominant and recessive S-alleles is also an important determinant of the evolution of the dominance network

Reproductive systems determine how genetic material is passed from one generation to the next, making them an important factor for evolution. Organisms that combine sexual and asexual/clonal reproduction are very widespread [… yet] the effects of their reproductive system on their evolution are still controversial and poorly understood.The aim of this thesis was to model the dynamics of genotype frequencies under combined sexual/clonal reproduction in dominantly diploid life cycles [. … A] state and time discrete Markov chain model served as the mathematical basis to describe [their] changes […] through time.The results demonstrate that partial clonality may indeed change the dynamics of genomic diversity compared to either exclusively sexual or exclusively clonal populations. […] Time has a crucial role in partially clonal populations and needs to be taken into account in any analysis of their genomic diversity.This thesis provides recommendations for data collection and a null hypothesis for the interpretation of population genetic/genomic data […]. Moreover, it includes new methods for the analysis of genotype-based population genetic Markov chain models. These results have a high potential relevance in several areas, ranging from basic research […] to applications in agriculture […], fisheries […] and nature conservation […]
