In photosynthetic eukaryotes, nonphotochemical plastoquinone (PQ) reduction is important for the regulation of photosynthetic electron flow. In green microalgae where this process has been demonstrated, the chloroplastic enzyme that catalyses nonphotochemical PQ reduction has not been identified yet. Here, we show by an RNA interference (RNAi) approach that the NDA2 gene, belonging to a type II NAD(P)H dehydrogenases family in the green microalga Chlamydomonas reinhardtii, encodes a chloroplastic dehydrogenase that functions to reduce PQ nonphotochemically in this alga. Using a specific antibody, we show that the Nda2 protein is localized in chloroplasts of wild-type cells and is absent in two Nda2-RNAi cell lines. In both mutant cell lines, nonphotochemical PQ reduction is severely affected, as indicated by altered chlorophyll fluorescence transients after saturating illumination. Compared with wild type, change in light excitation distribution between photosystems ('state transition') upon inhibition of mitochondrial electron transport is strongly impaired in transformed cells because of inefficient PQ reduction. Furthermore, the amount of hydrogen produced by Nda2-RNAi cells under sulfur deprivation is substantially decreased compared with wild type, which supports previous assumptions that endogenous substrates serve as source of electrons for hydrogen formation. These results demonstrate the importance of Nda2 for nonphotochemical PQ reduction and associated processes in C. reinhardtii. [less ▲]

Clownfishes (i.e. Amphiprion akallopisos) are territorial fishes that use sound production to defend their anemone territory. They live in social groups which display a size-based dominance hierarchy. In such a system, agonistic interactions are frequent and play an important role in the social organization. In addition, these interactions are often associated with sounds. In this study, we compared the sonic features between individuals of different sizes and in different sexual status (juvenile, male and female). The existent relationship between fish size and swimbladder size also implied to seek the swimbladder role in the sound production. Sound analyses showed that juveniles, males and females had distinct sounds in the dominant frequency and pulse duration. These differences were however not in relation to the sexual state; influence of sex on sonic features being mainly the result of a size dimorphism between sexes. Differences in calls were therefore due to the respective size of the emitter. This observation highlighted the role of the swimbladder as a resonance chamber. This role was also reinforced because the experimental filling of the swimbladder with physiological liquid significantly modified the acoustic features. In A. akallopisos, frequency and pulse duration are directly related to swimbladder size, and thus to fish size. This relationship provides strong evidence that the emitter could be identified by its calls. [less ▲]

L’ouvrage a pour objet central l’analyse des intégrations régionales dans la politique mondiale post-bipolaire. Une importante partie des travaux consacrés à l'explication du régionalisme partent d'une approche essentiellement endogène accordant une attention distraite aux déterminants exogènes. Pour comprendre la nature du nouveau régionalisme, il faut le situer dans une perspective globale qui tient compte de l’interrelation entre les niveaux national, régional et global. Bien que le régionalisme renvoie à des logiques internes propres, le phénomène est fortement conditionné et façonné par l’extérieur du fait qu’il évolue en interaction directe et constante avec le monde économique et politique international, et qu’il fait l’objet de politiques menées par des acteurs dominants de l’arène mondiale. Les déterminants extérieurs sont donc essentiels pour comprendre l’évolution du régionalisme. Pour étayer cette hypothèse, l’ouvrage se concentre sur l’étude du régionalisme latino-américain et plus précisément sur le Marché commun du Sud (MERCOSUR) qui fait l’objet de stratégie différente de la part de l’Union européenne et des Etats-Unis.

A formalism is presented to evaluate the Sivers function in constituent quark models. A non-relativistic reduction of the scheme is performed and applied to the Isgur-Karl model. The results obtained are consistent with a sizable Sivers effect and the signs for the u and d flavor contributions turn out to be opposite. The Burkardt Sum Rule is fulfilled to a large extent. After the estimate of the QCD evolution of the results from the momentum scale of the model to the experimental one, a reasonable agreement with the available data is obtained. A calculation of nuclear effects in the extraction of neutron single spin asymmetries in semi-inclusive deep inelastic scattering off 3He is also described. In the kinematics of forth-coming experiments at JLab, it is found that the nuclear effects arising within an Impulse Approximation approach are under control. © American Institute of Physics.

À travers une nouvelle approche de Notre-Dame-sous-Terre du Mont-Saint-Michel orientée par l’archéologie du bâti, a été mis en oeuvre pour la première fois, dans le cadre d’un programme CNRS, la confrontation croisée de plusieurs disciplines relevant de l’archéométrie. C’est à partir des mortiers et des charbons de bois, des briques ou terres cuites architecturales que le 14C, la thermoluminescence et l’archéomagnétisme ont cherché à préciser la chronologie d’édification des structures architecturales. Précédé d’une étude documentaire, d’une archéologie des élévations et de nouveaux relevés, ces travaux ont mis en évidence des datations recouvrant le Xe siècle et tendant à montrer que deux ensembles maçonnés se sont succédés.
