Plants need to avoid or dissipate excess light energy to protect photosystem II (PSII) from photoinhibitory damage. Higher plants have a conserved system that dissipates excess energy as heat in the light-harvesting complexes of PSII that depends on the transthylakoid delta pH and violaxanthin de-epoxidase (VDE) activity. To our knowledge, we report the first cloning of a cDNA encoding VDE and expression of functional enzyme in Escherichia coli. VDE is nuclear encoded and has a transit peptide with characteristic features of other lumen-localized proteins. The cDNA encodes a putative polypeptide of 473 aa with a calculated molecular mass of 54,447 Da. Cleavage of the transit peptide results in a mature putative polypeptide of 348 aa with a calculated molecular mass of 39,929 Da, close to the apparent mass of the purified enzyme (43 kDa). The protein has three interesting domains including (i) a cysteine-rich region, (ii) a lipocalin signature, and (iii) a highly charged region. The E. coli expressed enzyme de-epoxidizes violaxanthin sequentially to antheraxanthin and zeaxanthin, and is inhibited by dithiothreitol, similar to VDE purified from chloroplasts. This confirms that the cDNA encodes an authentic VDE of a higher plant and is unequivocal evidence that the same enzyme catalyzes the two-step mono de-epoxidation reaction. The cloning of VDE opens new opportunities for examining the function and evolution of the xanthophyll cycle, and possibly enhancing light-stress tolerance of plants.

Feminist movements have allowed many female authors to become decisive and influential figures in literary history by studying their experiences, voices and forms of resistance. This thesis, however, focuses specifically on religious women, those seeking divine comfort outside the confines of institutional laws, or those who, out of protest, are caught in the middle. Founded on historical and feminist perspectives, this study examines the heterodox resistance of six French women living within or outside of Church boundaries during the 17th and 18th centuries: two eras that are particularly significant for women’s progress and modernity. This work strives to demonstrate how these women, doubly subjected to Church discourse and that of society, managed to live out their vocation (female and Christian) and make social, cultural and religious statements that contributed to changing the place of women in society. It aims to grasp the similarities and differences between the actions and ideas of women belonging to both the religious and secular spheres. Regardless of the century, the space and their background, women resist to masculine, patriarchal, ecclesial, political and social mediation and institutions. In locating examples of how they oppose the practices, rules and constraints that are imposed upon them, as well as of their exclusion from the socio-political space, this thesis also seeks to identify epistemological changes that mark the transition from the 17th to the 18th century. This thesis firstly outlines the necessary feminist theory upon which the project is based before identifying the evolution of women’s positions within the socio-ideological and political framework in which they lived. The questions of confession and spiritual direction are of particular interest since they serve as prime examples of masculine mediation and its issues and consequences – most notably the control of the female body and mind. The illustration of bodily metamorphoses bear testament to ideological changes, cultural awareness and female subjectivity, just as the scriptural inscriptions of unorthodox ideas and writing. The female body, both object and subject of the quest for individual and collective liberties, attests, in this way, to the movement towards Enlightenment values of freedom and justice.

Situé dans la vallée de la Birse, Reinach appartient à l'arrière-pays de Bâle et est localisé dans la plaine du Rhin supérieur. Cette zone jouant un rôle important pendant la Guerre des Gaules ainsi que durant le Ier siècle apr. J.-C., on doit envisager de forts bouleversements du peuplement de cette région au changement d'ère. Grâce à des conditions favorables, les structures de La Tène finale au lieu-dit "Mausacker" sont très bien conservées et permettent de restituer une ferme laténienne avec deux phases différentes. Au même endroit se situe une villa gallo-romaine, mieux connue par ses enclos funéraires que par les structures résidentielles. Des études pluridisciplinaires financées par le Fonds national suisse (FNS) sont en cours pour les vestiges laténiens et gallo-romains de Reinach-Nord.
