Texte intégralThe aim of this thesis was to characterized the spatial patterns of inter- and intraspecific diversity within riverine networks, to better understand the ecological and evolutionary processes underlying them and to explore how the different facets of biodiversity interact with one another. First, I developed novel statistical approaches allowing the application of causal modeling to data in the form of pairwise matrices, thus allowing the study within integrative frameworks of several biodiversity facets at the alpha and beta levels. I then studied integratively the patterns of interspecific and intraspecific genetic diversity and of intraspecific genetic and intraspecific phenotypic diversity within the Garonne-Dordogne river basin. Finally, I used an eco-evolutionary metapopulation dynamics model to assess the impacts of the structure and environmental gradients that characterize riverine networks on local adaptation

Texte intégralConditions and proliferation in a wide range of environments from soil to mammalian host cells. The genetic heterogeneity in L. monocytogenes is reflected on its diversified clonal structure which correlates, to some extent, with phenotypic traits such as virulence or stress resistance. The thesis investigated two most prominent phenotypes, biofilm formation and virulence potential, from various perspectives using state-of-the art technologies. Throughout the studies, large panels of isolates were used to represent the intraspecific diversity. Unfavourable stimuli such as cold shock and nutrient deprivation induced bacterial adhesion step. Addition of NaCl to growth cultures stimulated biofilm production and, surprisingly, it significantly intensified biofilm maturation of nutrient-deprived cells. High degree of variation in relative biofilm productivity was observed among serotypes, genotypes, as well as isolates across culture conditions, however, certain genotype (clonal complex 26) revealed distinctively higher biofilm production under cold temperature (10°C) suggesting an association of genotype with biofilm phenotype. Pan-GWAS identified a number of genes among which those implicated in functions such as ‘transformation/competence’, ‘phage-related genes’, and ‘metabolism of phosphate’ will need further investigations for their roles in biofilm formation. RNA sequencing analysis revealed high intraspecific heterogeneity in basal transcriptome profiles that featured the role of regulatory network including certain transcriptional factors with key roles in virulence such as σB, PrfA, and CodY. The transcriptomic plasticity between lineage I and II as well as hyper- and hypovirulent genotypes supported the evolutionary and epidemiological characteristics of L. monocytogenes. Moreover, the central metabolic pathway was implicated in the infection in Galleria mellonella model system. Conclusively, the thesis explored intraspecific diversity in L. monocytogenes and resulted in ample phenotypic, genomic, and transcriptomic findings. With the integrative omics approach in listeriology, the present work will contribute to unveiling the physiology and pathogenesis of the bacterium

Texte intégralThis work investigated gametophytic and tetrasporophytic phases of green, red and brown morphs of Gracilaria domingensis in laboratory. The reproductive performance was tested considering the following: i, number of cystocarps produced; ii, number of carpospores and tetraspores released; iii, diameter of these spores; and iv, survival of carpospores and tetraspores in different nutrient, irradiance and UV-B conditions. The somatic performance of different life phases was tested considering the following: i, growth rates on different nutritional conditions; ii, growth rates on different UV-B conditions; iii, nitrate reductase (NR) activity on different nutritional conditions; iv, photosynthetic rates; and v, mycosporine-like amino acids (MAAs) synthesis on different UV-B conditions. Carpospores originated by the cross of red males x red females were released by a longer period of time when compared to the other carpospores strains. This was almost the only difference found in the reproductive performance among different strains, and could make a greater number of the red strain propagules available for settling. This result could represent competitive advantages in the natural environment. Green plants showed greater values of maximum photosynthesis, a greater MAAs synthesis when exposed to UV-B radiation, and greater amounts of total soluble proteins when compared to the red plants. These responses suggest adaptations to high irradiances and oligotrophic environments. Heterosis was observed in one of the two brown tetrasporophyte strains considering, at least, one of the following parameters: maximum photosynthesis and photosynthetic efficiency; growth rates; total soluble proteins content; NR activity; and survival of carpospores. The heterosis related to these aspects could favor the maintenance of the green allele in nature. The two brown tetrasporophytic strains showed different performance considering the survival of spores and growth rates, which indicates that the two genotypes are expressed in different ways depending on the abiotic conditions. The number of spores released was the same for carpospores and tetraspores when expressed by the fresh biomass of the fertile plants. However, survival of tetraspores was always higher. The somatic and reproductive performance of tettrasporphytes were higher than the gametophytes ones for most of the conditions tested, regardless the strain. These results demonstrate that the different life phases of G. domingensis have specific metabolic characteristics, which contributes to a higher phenotypic plasticity of this species. The differences found among the strains were slight. If the green allele promoted very superior advantages when compared to the ones promoted by the red allele, or vice-versa, it would be expected that, within time, one of the two morphs would exclude the other. The coexistence of the morphs, however, indicates that each one of them must occupy a slightly different niche, which provides advantages to the species concerning heterogonous environments, and /or environmental changes, and enable it with a greater adaptative capacity.

Texte intégralFusarium avenaceum is a filamentous fungus infecting many plants and is one of the causal agents of the Fusarium Head Blight disease in wheat and barley. During plant infection, the fungus can produce secondary metabolites that are toxic for human and livestock (mycotoxins), among which the enniatins. Enniatins belong to the group of “emerging mycotoxins”: first identified as early as 1950, the increasing occurrence of enniatins has only been documented over the last twenty years. Currently, enniatins are neither routinely analysed in grain harvests nor legislatively regulated, even though they are widespread and can be encountered in high concentrations. Diversity of enniatin-producing strains as well as the mechanisms by which their biosynthesis can be modulated during plant infection and/or in response to environmental conditions are poorly known. These gaps of knowledge hinder the development of tools for controlling and mitigating their presence in crops. In the present study, a comprehensive characterisation of the phenotypic diversity within the F. avenaceum species has been carried out. One of the studied phenotypic traits was the effect of pH variations on the fungal growth and toxin production, which has led to evidence various response profiles between strains. To go further, the role of FavPac1, the homologue of pacC/RIM101 encoding a transcriptional factor involved in the response to ambient pH in fungi, has been studied. Construction and phenotyping of deleted mutants, Fav∆Pac1, for four different F. avenaceum isolates have allowed suggesting an involvement of FavPac1 in the modulation of enniatin production and of the expression of biosynthetic genes induced by pH variations. Lastly, with the aim to identify alternatives to synthetic fungicides, the capacity of plant phenolic compounds to inhibit the yield of enniatins has been investigated. The antifungal and anti-mycotoxin properties of hydroxycinnamic acids have been shown; ferulic acid has been highlighted as the most potent compound
