Carrot domestication and breeding have led to a diversity of cultivated carrot types exhibiting a high variability for carotenoid content in the root. Carotenoid biosynthesis genes are probably involved in carotenoid level differences, and could have been a selection target for plant breeding. The objectives of this thesis were to investigate the role of transcriptional variations for carotenoid biosynthesis genes on carotenoid accumulation during root development in variously coloured carrots, and to characterise the impact of selection and demographic history, particularly genetic structure, on carotenoid biosynthesis gene sequence variability in cultivated carrots. . . .

During chemotherapy, cancer cells frequently succeed to escape the toxic effects of drugs by developing mechanisms of chemoresistance which often result from the presence of an efflux system of these drugs. Such a chemoresistance is correlated to the MDR (MultiDrug Resistance) phenotype and associated to overexpression of membrane ATPases belonging to the ABC (ATP-Binding Cassette) transporters. The ABCG2 transporter belongs to this large family of proteins. Sequence alignment allowed the identification of a specific (LSGGE) sequence in ABCG2, which is quite similar to the canonical sequence signature (VSGGE) of all ABC transporters. Point mutation of these residues into alanine produced a loss of function in L352A and S353A mutants, as observed in transport and on ATPase activity. Structure-activity relationships drawn from some compounds among the family of flavonoids allowed the identification of MBLI 97, boeravinone G, MHT and ABI as potent and ABCG2-specific inhibitors, able to revert multidrug resistance and chemosensitize cell growth. The study of specific sequences and use of specific inhibitors of these transporters constitute strategies to abolish cancer cell chemoresistance and to increase the efficiency of chemotherapeutic treatments

Markov chains, as a universal model accounting for finite memory, discrete valued processes, are omnipresent in applied statistics. Their applications range from text compression to the analysis of biological sequences. Their practical use with finite samples, however, systematically require to draw a compromise between the memory length of the model used, which conditions the complexity of the interactions the model may capture, and the amount of information carried by the data, whose limitation negatively impacts the quality of estimation. Context trees, as an extension of the model class of Markov chains, provide the modeller with a finer granularity in this model selection process, by allowing the memory length to vary across contexts. Several popular modelling methods are based on this class of models, in fields such as text indexation of text compression (Context Tree Maximization and Context Tree Weighting). We propose an extension of the models class of context trees, the Parcimonious context trees, which further allow the fusion of sibling nodes in the context tree. They provide the modeller with a yet finer granularity to perform the model selection task, at the cost of an increased computational cost for performing it. Thanks to a bayesian approach of this problem borrowed from compression techniques, we succeeded at desiging an algorithm that exactly optimizes the bayesian criterion, while it benefits from a dynamic programming scheme ensuring the minimisation of the computational complexity of the model selection task. This algorithm is able to perform in reasonable space and time on alphabets up to size 10, and has been applied on diverse datasets to establish the good performances achieved by this approach
Meslin, Camille. "Analyse de l'évolution de gènes impliqués dans la reproduction". Thesis, Tours, 2011. http://www.theses.fr/2011TOUR4030.
Genes involved in reproduction evolve rapidly and are often under positive selection. The objective of this work was to study the evolution of some of these genes, potentially involved in speciation, through their involvement in prezygotic barriers.Our results show that for the SAL1 gene, involved in pheromonal recognition in pig, three amino acids under positive selection participate in the specific binding of the pig pheromone. We also perform an evolutionary analysis of genes experimentally shown to be involved in the sperm-oocyte interaction during fertilization. Each of the nineteen species studied exhibit a particular pattern of evolution, characterized by gene gains and losses, as well as the position of amino acids under positive selection. The divergent evolution of all these genes could be involved in speciation or at least in the reinforcement of species barriers.Finally, the PhyleasProg web server was designed during the thesis. This tool permits to scientists with no experience in phylogenetic analyses to acquire a large number of results quickly and easily on the evolutionary history of their genes of interest
