Der volle Inhalt der QuelleThe study of the distribution of the genetic variation within and across populations provides insights into the evolutionary history of a species. Moreover, the access to large genomic datasets allows the investigation of the evolutionary processes that shape the species' segregating variation. In this work, we retrace the evolutionary history of the species Saccharomyces cerevisiae through the detection and classification of shared polymorphisms with its sister species Saccharomyces paradoxus. We identify shared polymorphisms acquired because hybridization followed by introgression and polymorphisms that persist across the process of speciation and diversification resulting in instances of incomplete lineage sorting (ILS). We define a dataset of biallelic diagnostic single nucleotide polymorphisms between Saccharomyces cerevisiae and Saccharomyces paradoxus that we use as diagnostic marker to describe the genomic composition of 1,673 S. cerevisiae, for which short-read whole-genome sequencing were publicly available. We develop a marker-based method for the detection and classification of diagnostic markers organized either in 1) blocks of consecutive S. paradoxus markers or in 2) genome-wide isolated S. paradoxus markers. For the blocks, we describe the boundaries, the distribution across the S. cerevisiae collection and we retrace the S. paradoxus origin by sequence comparison with telomere-to-telomere whole genome assemblies of the main S. paradoxus populations. For a recurrent event, we performed an assay to evaluate the fitness effect of carrying a S. paradoxus haplotype at a single locus encompassing a gene-pair involved in the degradation of toxic compounds for the yeast. We demonstrate that the S. paradoxus haplotype confers an advantage over the S. cerevisiae haplotype in environmental conditions that are characteristic of the niche that the S. cerevisiae population inhabits. For the isolated markers, we apply a classical method for detecting signatures of incomplete lineage sorting, which can explain the excess of genome-wide distributed S. paradoxus markers in certain populations of S. cerevisiae. We show convincing evidence of retention of ancestral alleles in a single wild S. cerevisiae population that stands at the root of the species. We speculate about the persistence of such ancestral variation because of reduced possibility of outcrossing with other S. cerevisiae populations into the wild due to fewer generations and less dramatic bottlenecks that were instead experienced by the other lineages during dispersal and domestication. Overall, we retraced histories of divergence and secondary contacts across S. cerevisiae and S. paradoxus populations and unveiled a compelling case of interspecies introgression with a functional outcome

Der volle Inhalt der QuelleInterspecific hybridization is more and more studied these last years and its consequences on species evolution are diverse. The literature especially points out its potential impact on new species emergence and the number of hybrid speciation cases is increasing. My work aims at understanding how interspecific crosses can initiate the rise of a new hybrid lineage and stimulate the diversification of living organisms.Reviewing the examples of animals hybrid species described in the literature allows me, in the first part of this work, to identify the main patterns associated with the process of hybrid speciation. I observe in particular that, if the recombination of parental characteristics is always the main driver of hybrid speciation, it leads to various patterns in hybrid species establishment. I also discuss methodological issues concerning the identification of hybrid species, which limit our capacity to estimate the prevalence of such process in species evolution dynamic.In the second part of this work I investigate the process of hybrid speciation in a complex of closely related butterfly species of the genus Coenonympha. I show that among the four lineages composing the complex, two originated through hybridization events. Their genetic, ecological and morphological characteristics allow us to better understand how their recombinant phenotype led to their emergence and their isolation from parental species.The evolutionary history of these butterflies is discussed in detail in the last part of this work. The results obtained in this particular case are compared with other examples of hybrid species and with theoretical expectations from literature. This example adds its specificities to the current knowledges about hybrid speciation and evolutionary impacts of hybridization

Der volle Inhalt der QuelleTiivistelmä Luonnonvalinta ja populaatioiden historian demografia tekevät lajiutumisesta monimutkaisen tapahtumaketjun. Luonnonvalinnan ja demografisten tekijöiden vuorovaikutusta on paras tutkia samanaikaisesti, kun tarkastellaan lajiutumiseen vaikuttavia ominaisuuksia. Tällaisia ovat esimerkiksi ilmastoon sopeutumiseen liittyvät ominaisuudet. Lähisukuiset havupuulajit tarjoavat erinomaiset mahdollisuudet tähän työhön. Tutkin geneettistä muuntelua yhtäältä ilmastosopeutumiseen liittyvissä ns. ehdokasgeeneissä ja toisaalta neutraaleiksi oletetuissa verrokkigeeneissä sekä sytoplasman genomeissa kahdessa lähisukuisessa mäntylajissa Pinus massoniana Lamb. ja Pinus hwangshanensis Hisa, joiden populaatiot esiintyvät joskus erillään toisistaan (allopatrisesti), toisinaan vierekkäin (parapatrisesti). Mittasin muuntelun määrää ja etsin merkkejä valinnan vaikutuksesta. Vertasin erilaisia lajiutumismallien parametrejä verrokki- ja ehdokasgeeneissä. Käytin simulaatioita etsiäkseni parhaat demografiset ja lajiutumiseen liittyvät mallit. Vertasin kloroplastien ja mitokondrioiden genomien sekvenssien lajinsisäistä ja lajien välistä muuntelua allopatrisissa ja parapatrisissa populaatioissa tutkiakseni onko lajien yhteinen muuntelu seurausta siitä että lajien eriytymisestä on kulunut vain vähän aikaa vai siitä että sen jälkeen on tapahtunut geenivirtaa. Kauan sitten tapahtunut valinta on vaikuttanut samalla tavalla kumpaankin lajiin, osin koska tutkimus kohdistui myös niiden yhteiseen edeltäjälinjaan. Äskettäinen valinta taas oli suuremmassa määrin kummallekin lajille ominaista. Viime aikojen ilmastoon liittyvä valinta on voinut vähentää geenivirtaa ehdokasgeeneissä, mikä voisi edistää ekologista lajiutumista. Tuman DNA:n muuntelu jakautuminen tuki sitä mahdollisuutta että lajien yhteinen geneettinen muuntelu johtuu äskettäisestä geenivirrasta, ei vain siitä että lajiutuminen on niin varhaisessa vaiheessa. Mitokondrioiden geeneissä lajeilla yhtä paljon yhteistä muuntelua sekä allopatrisissa että parapatrisissa populaatioissa, mikä tukee sen sijaan eriytymisen jälkeistä epätäydellistä muuntelun erilaistumista. Eri genomit heijastavat lajiutumisprosessin eri vaiheita. Väitöskirjan tulokset ovat osaltaan tuottaneet uutta tietoa lajiutumisesta ja valinnasta. Lisäksi niillä on merkitystä ilmastomuutoksen vaikutusten ymmärtämisessä ja metsänjalostuksessa

Der volle Inhalt der QuelleGenomes are affected by conflicting selective regimes. This is particularly well illustrated by the concept of semi-permeable barriers to gene flow, as found in the hybrid zones literature. Some genes contribute to the prevention of mixing between differentiated genetic lineages, either because they are involved in adaptation to local environmental conditions, or because they are incompatible with alleles from other genetic lineages. Other parts of the genome are either neutral, or subjected to selection which tends to homogenize the genetic lineages. In the first part of this thesis, models of the evolution of reproductive isolation are presented to explain the isolation patterns observed in experimental hybridizing crosses between incipient species. Using standard models of Dobzhansky-Muller genetic incompatibilities, it is shown that the asymmetry and complexity of incompatibilities are not well explained by there being an “evolutionary sieve”, i.e. a different rate of accumulation between incompatibilities. A complementary approach to quantitative modeling (an extension of Fisher's Geometric Model) then clarifies which conditions of divergence between allopatric lines led to highly deleterious effects in hybrid genotypes. The relative importance of mean levels of fitness epistasis, the distribution of mutation sizes, and the way lineages adapt to new environmental conditions is discussed. The second part of this thesis takes advantage of technical advances in genomics to study the history of speciation and adaptation in a non-model species complex, Mytilus mussels. A statistical method of inferring speciation scenarios is presented. Results show that European mussels experienced a complex history of strict divergence followed by a period of periodic connectivity. In agreement with the concept of semi-permeable barriers to gene flow, it is shown that introgression rates are heterogeneous along the genome. Next, genome scans of differentiation were conducted between pairs of populations of the species complex. The analysis of genetic variation and allele genealogies on a small chromosomal scale allowed to reconstruct the evolutionary history of more than 1000 genomic regions. This analysis reveals that a major cause of intraspecific differentiation is the differential introgression of foreign alleles. Overall, this thesis shows not only that biogeography of speciation, i.e. the temporal and spatial patterns of gene flow, play a major role in our understanding of existing biodiversity, but also its amazing complexity and extent of its impact on genome evolution
