Full textIn sexual organisms, recombination suppression can evolve in specific genomic regions to protect beneficial allelic combinations, resulting in the transmission of multiple genes as a single locus, which is called a supergene. Supergenes determine complex phenotypes, such as gender in organisms with sex chromosomes. Some sex chromosomes display successive steps of recombination suppression known as “evolutionary strata”, which are commonly thought to result from the successive linkage of sexually antagonistic genes (i.e. alleles beneficial to one sex but detrimental to the other) to the sex-determining region. There has however been little empirical evidence supporting this hypothesis. Fungi constitute interesting models for studying the evolutionary causes of recombination suppression in sex-related chromosomes, as they can display non-recombining mating-type chromosomes not associated with male/female functions. Here, we studied the evolution of recombination suppression on mating-type chromosomes in the Microbotryum plant-castrating fungi using comparative genomic approaches. In Microbotryum fungi, mating occurs between gametes with distinct alleles at the two mating-type loci, as is typical of basidiomycete fungi. We showed that recombination suppression evolved multiple times independently to link the two mating-type loci from an ancestral state with mating-type loci on two distinct chromosomes. Recombination suppression either linked the mating-type genes to their respective centromere or linked mating-type loci after they were brought onto the same chromosome through genomic rearrangements that differed between species. Both types of linkage are beneficial under the intra-tetrad mating system of Microbotryum fungi as they increase the odds of gamete compatibility. Recombination suppression thus evolved multiple times through distinct evolutionary pathways and distinct genomic changes, which give insights about the repeatability and predictability of evolution. We also reported the existence of independent evolutionary strata on the mating-type chromosomes of several Microbotryum species, which questions the role of sexual antagonism in the stepwise extension of non-recombining regions because mating-types are not associated with male/female functions. Previous studies reported little phenotypic differences associated to mating-types, rending unlikely any antagonistic selection between mating types (i.e. “mating-type antagonism”, with genes having alleles beneficial to one mating-type but detrimental to the other). The genes located in non-recombining regions on the mating-type chromosomes can be differentially expressed between mating types, but our analyses indicated that such differential expression was more likely to result from genomic degeneration than from mating-type antagonism. Deleterious mutations are indeed known to accumulate in non-recombining regions resulting in modifications of gene expression or of protein sequence. We concluded that antagonistic selection cannot explain the formation of evolutionary strata in Microbotryum fungi. Alternative mechanisms must be therefore be considered to explain the stepwise expansion of non-recombining regions, and they could also be important on sex chromosomes. This work thus prompts for future studies to identify further evolutionary strata not associated with male/female functions as well as to elucidate their evolutionary causes and consequences in terms of genomic degeneration

Full textThe first part of my thesis concerns two different mechanisms of the Y being rescued by the X. Firstly, I contributed to a controversy on mammalian dosage compensation. During the 60s Susumo Ohno hypothesized a two-step dosage compensation mechanism. In males, the high loss of Y-linked genes led to a dosage imbalance: these genes were previously present in two allelic copies and became unicopy, meaning that their expression has been halved. According to Ohno’s hypothesis, in response to this imbalance the mammalian X would have doubled its expression in the two sexes, resulting in a to high expression in females. This second dosage imbalance would have been resolved by the random inactivation of one of the two Xs in females. Whereas the second part of Ohno’s hypothesis, the X-chromosome inactivation, has been well studied, the first part remained speculative until the 2000s. I studied human X-linked expression data and was able to show, concomitantly with other authors, that the first part of Ohno’s hypothesis is not totally true as only some of the X-linked genes are hyperexpressed. I later participated in the writing of a review aiming to give an alternative hypothesis for the evolution of X-chromosome inactivation in mammalian females than dosage compensation. Secondly, I studied signatures of X-Y gene conversion in several genes within numerous primate species. Myresults led me to discuss if these events were indeed selected for. I hypothesize that these gene conversion events occurred in a neutral manner. These two different studies suggest that the X chromosome may not be as much a help for the Y as has been suggested. Lastly, moving away from model species, I studied the peculiar sex chromosomes of a brown alga: Ectocarpus siliculosus. This work allowed me to test if the current hypotheses on sex chromosome evolution still hold in a eukaryotic group that diverged from animals more than one billion years ago

Full textTherian mammals have an extremely conserved XX/XY sex determination system. Their highly differentiated and specialised sex chromosomes are thought to prevent any modification; however, a dozen species harbour unconventional systems. In the African pygmy mouse Mus minutoides, all males are XY, and there are three types of females: the usual XX but also XX* and X*Y ones (the asterisk designates a sex reversal mutation on the X chromosome, which evolved almost 1 million years ago). The evolution of such a system is a paradox, as X*Y females are expected to face high reproductive costs (loss of YY embryos, meiotic problems…), which should prevent the maintenance of the mutation. To better understand the evolution of this curious system, we first tried to identify the evolutionary mechanisms involved in the emergence and maintenance of the X*. The combination of empirical data and a theoretical approach based on population genetics models showed that two mechanisms participate in the maintenance of the system: the greater breeding success of X*Y females and the presence of sex chromosome transmission distorters (males transmit their Y more often in crosses with XX or XX* females and their X in crosses with X*Y females), the second mechanism likely being the trigger for the initial spread of the feminising chromosome. We then investigated the consequences of the evolution of this unusual system with three sex chromosomes. First on the phenotype, revealing that despite X*Y females have typical female anatomy and morphology, they resemble males on certain aspects of behaviour: they are more aggressive and less anxious than XX and XX* females. Then on the sequence and structural evolution of the X and X* (based on NGS data), showing that the two chromosomes have started diverging. Altogether, these results shed light on the constraints acting on sex determination systems with highly heteromorphic sex chromosomes and show that rare conditions can loosen these constraints. They also provide valuable insight into the impact of sex chromosome complement on phenotype, and inform on the evolutionary forces acting on sex chromosomes in that kind of polygenic sex determination system
