Full textGreko, a dying language, is a modern Greek dialect, currently spoken in south of Italy (region of Calabria). As Greko speakers are all bilingual, the grammatical description of the dialect involves the sociolinguistic study of the community. Classified as a meridional modern Greek dialect, Greko presents certain particularities : geminate consonants, simplifications in the system of cases, reduction of aspectual oppositions, development of periphrastic verbal constructions. . . In most cases, these particularities should be studied in relation to Calabrese, the romance dialect spoken in Calabria. The comparative approach brings forth the interaction between Greko and Calabrese, as well as the areal character of certain grammatical trends
Vaillant, Adrien Alp. "Une langue en voie de disparition : le salar au sein de la turcophonie." Thesis, Sorbonne Paris Cité, 2017. http://www.theses.fr/2017USPCF019.
Full textSalar is a Turkish dialect most speakers of which live in the county of Xunhua (35°05 north, 102°03 east) in the south-eastern part of the Chinese province of Qinghai where they have been present since the end of the fourteenth century. In spite of the fact that there has been lately an increase in the studies concerning this language, it is still a poor relative of turkology. Carried out with the aim of making it better known, with the support of the available documentation and data collected by the author in his investigation in the field, this thesis offers not only a phonological, grammatical and lexical description of Salar, but also, to the best of the author’s knowledge, for the first time, a detailed study of its nearly extinct traditional writing system that constitutes an adaptation of the Arabic alphabet. We have been particularly careful to take into account the links uniting Salar with other dialects, present and ancient, which form the Turkish domain (particularly with the Oghuz group to which this variety seems to belong) notably through the comparison with Turkey Turkish, based on the translations into the latter of the grammatical items dealt with. Classified as an endangered language by UNESCO, Salar is going through a critical period. The problems raised by its status in China, the position it occupies in the society where it is spoken and the representations to which it is subjected, have also been addressed in this work. A section has been devoted to the identification of a diglossic language situation in the context of which, among the concerns raised by some Salars about the future of their language, lies a project aiming at its revitalisation

Full textLand use often provokes the fragmentation and the reduction in population size of concerned species, consequences which may have major negative effects on genetics, demography or reproduction and therefore on species survival. Dianthus gratianopolitanus Vill. (Caryophyllaceae) is a carnation endemic to Europe. This species has small and scattered populations, growing mainly on calcareous grasslands. This habitat is strongly threatened and has dramatically decreased during the twentieth century. Despite a current distribution that may correspond to that of a glacial relict and a strong fragmentation, genetic differentiation between populations is small, which may indicate a relatively recent fragmentation. Furthermore, genetic diversity is higher than expected for a species with such a fragmented distribution of small populations or in comparison with D. Sylvestris Wulf, which occurs in similar habitat but is far more common. These results may be attributable to the clonal abilities of D. Gratianopolitanus, as observed in Maianthenum bifolium (L. ) Schmidt. Therefore, extinction risk is probably less due to a loss of genetic diversity, even if the probable high selfing rates (revealed by heterozygote deficits) may lead to loss of genetic variation important for adaptability in the long run. Nevertheless, the large population (more than 200 tufts, located at the Chasseron, Switzerland) suffers from pollen limitation, a probable recruitment limitation and a possible genetic load. To confirm this last point, crossings between individuals from different populations are needed
Melser, Su. "Implication du Glucosylceramide dans la voie sécretoire des plantes." Thesis, Bordeaux 2, 2009. http://www.theses.fr/2009BOR21637/document.
Full textThe role of lipids as molecular actors in protein secretion is not well understood in plants. Glucosylceramide (GlcCer) is synthesized by Glucosylceramide Synthase (GCS) in plants and constitutes a key complex sphingolipid in membranes, but little is known about the plant cellular requirements for GlcCer. This study relied upon the block of GlcCer biosynthesis, by the use of inhibitors in tobacco and Arabidopsis, and the production of Arabidopsis mutants, to determine the impact of GlcCer biosynthesis on plant cell endomembrane dynamics. In a comprehensive approach that included lipid biochemistry, live cell imaging, ultrastructural studies by Transmission Electron Microscopy, and whole plant developmental studies, we have gained a better understanding of the impact of GlcCer in plant cells that can be summarised as follows: (1) Based on theoretical analysis and live-cell microscopy the GCS is located to the Endoplasmic Reticulum (at the beginning of the secretory pathway) in plant cells, (2) PDMP is a specific inhibitor of GCS in plants, (3) Disruption of GlcCer biosynthesis using PDMP and genetic approaches showed that GlcCer is important for normal protein trafficking and endomembrane dynamics, notably in the maintenance of Golgi structure, (4) The regulation of protein trafficking by the synthesis of GlcCer could be critical in the establishment and maintenance of cell polarity, as suggested by defects in the localisation of polar markers in Arabidopsis treated with PDMP, and (5) A block in GlcCer synthesis may be conducive to severe defects in plant development, as Arabidopsis mutants showed abnormal primary root growth and inability to develop to reproductive stages. Potential interactions between GlcCer and the transport machineries are discussed, as well as cellular mechanisms that may be set off following a disruption of GlcCer biosynthesis in plant cells

Full textIn eukaryotic cells, membrane lipids are essential for compartmentalization and regulation of secretory pathways. According to their physical properties, they are essential to membrane curvature and regulation of endomembrane morphodynamics, organelle morphology, and vesicles. In animal cells, lysophosphatidic acid acyltransferases (LPAAT) are involved in the regulation of endomembrane trafficking, but nothing is known about their role in plants. In Arabidopsis thaliana, five LPAATs were identified. We determined their specific enzymatic activity for lysophosphatidic acid (LPA) to produce phosphatidic acid (PA). I then characterized their subcellular localization in the endomembrane system of the secretory pathway and their potential role in this pathway using genetical (knockout mutants), biochemical (activity inhibitors, lipid analyzes) and imaging (confocal microscopy) approaches. Using the single, double and triple mutant lines for LPAAT genes that I produced, in addition to CI-976 treatment that inhibits LPAAT activity, I showed, after lipid analysis, that phosphatidic (PA) dependent on LPAAT activity is essential for the trafficking of the auxin carrier PIN2 and the aquaporin PIP2,7 to the plasma membrane.This work highlights the importance of lipid regulation in endomembranes and thresholds under which membrane homeostasis can be finely disturbed to the point of causing dysfunction of the secretory pathway
