Evolutionary Status of Mitochondrial Ribosomal Protein Genes rps19 and rpl2 and their Transfer to the Nucleus in GrassesAtluri, Sruthi January 2015 (has links)
Massive mitochondrial gene transfer to the nucleus occurred very early during eukaryotic evolution following endosymbiosis, and is still ongoing in plants. Tracking recent gene transfer events can give us insight into the evolutionary processes by which a transferred gene becomes functional in the nucleus and how its protein gets targeted back into the mitochondrion, where it is needed. Rps19 and rpl2 are two such ribosomal protein genes that are known to have been transferred to the nucleus, many times independently during flowering plant evolution. My research project focusses on determining the status and expression of rps19 and rpl2 in the mitochondrion and nucleus of selected grasses and in particular brome (close relative to agronomically important crops such as wheat, rye and barley). My results at the level of DNA and RNA (PCR and RT-PCR, respectively) show that the mitochondrial brome rpl2 copy is a pseudogene while its functional gene is in the nucleus. The brome mitochondrial genome has a copy of rps19 which is transcribed and C-U edited. Surprisingly, the brome nuclear genome also has functional copies of rps19.The targeting sequence for the nuclear rps19 gene was acquired from duplication of mitochondrial targeting heat shock protein (hsp70) presequence. Comparative analysis strongly suggests that a functional rps19 gene was transferred to the nucleus before rice and maize lineages split and now that brome rps19 has been found to be present in both compartments, this implies a transition stage of about 60 million years. Oats was found to have a functional rps19 copy in the nucleus and has a novel presequence due to lineage specific rearrangements and exon shuffling. Functional paralogous copies were found in wheat, and maize while barley lost one of the copy. Thus, following transfer, duplication of rps19 gene must have occurred in the ancestor of barley and wheat clade. Maize might have had a recent duplication or gene conversion events along its lineage as its paralogous copies are very similar to each other. More information is needed to determine if this duplication event extends to wheat-brome, wheat-oats or even before rice and maize split. Barley was also found to have a recent independent DNA mediated transfer in addition to the common transfer, as it possesses an unedited nuc-mt rps19 in its nuclear genome. This suggests that barley must also have had a transition stage for ~60MY and lost its mitochondrial copy very recently.

La route des vins de Brome-Missisquoi : vers la construction d'une identité régionaleBricault, Christine 12 April 2018 (has links)
À première vue, le circuit touristique ou la route à thème semble être une simple mise en réseau des ressources touristiques d'une région ou d'un territoire. Par l'étude de la Route des vins de Brome-Missisquoi (région touristique des Cantons-de-l'Est), nous entrons au cœur du processus de création de l'image touristique d'une région. Un regard sur la Route des vins à travers la situation de ses vignobles (chapitre 1), à travers l'expérience de ses touristes (chapitre 2) et à travers son processus de création, de mise en place et d'évolution (chapitre 3) montre comment le phénomène transcende le cadre marketing et devient un prétexte pour l'étude des relations entre l'identité, le tourisme, la mobilité, le territoire et le patrimoine. L'ensemble de la démarche s'inscrit dans une approche de recherche ethnologique. De ce fait, le projet s'appuie sur un important travail de terrain par lequel plusieurs types de sources ont été rassemblés. L'enquête orale auprès de vignerons de la Route des vins et d'intervenants régionaux veillant à la mise en place et à la promotion de la route constitue la principale méthode de collecte. Le mémoire tente de comprendre ce qui fait le succès et la pérennité de la Route des vins de Brome-Missisquoi. Dans un premier temps, le portrait des vignobles et des parcours vignerons montre clairement la diversité des cheminements et des réalités de chacun. Puis, l'exemple de l'expérience touristique fait comprendre l'importance des activités et des services offerts au vignoble. La Route des vins est donc appréhendée par ses principaux acteurs. Ce sont ces mêmes acteurs, vignerons, touristes et intervenants régionaux qui, chacun à leur façon, combinent leurs perceptions et intentions et participent à la réalité complexe de la route thématique. Ce mémoire jette un regard singulier sur la dynamique particulière qui entoure la création et l'existence de la Route des vins de Brome-Missisquoi.
