Testo completoThis work deals with the metalorganic vapour phase epitaxy (MOVPE) of nitride laser diodes working under electrical injection. The doping of GaN:Si and GaN:Mg layers has been optimized in order to reduce the access resistances of the laser. The structure of the (In,Ga)N active area has been calibrated to control the optical emission from violet to yellow wavelengths. A strong electric field has been observed in the quantum well (QW) during this study. Due to Quantum Confined Stark Effect a compromise between the thickness and the In composition of QWs is essential in order to obtain a strong radiative efficiency. Phenomena relating to (Al,Ga,In)N confinement layers have been treated. Theorical and experimental studies allowed pointing out the key points to optimize the vertical conduction of AlGaN/GaN superlattices. A study regarding AlInN layers lattice matched with GaN has been made to limit the crystallographic defects and to increase the optical confinement of the confinement layers. To validate the optimization of each building block, we have grown several laser structures, and the devices have generated a laser emission under electrical injection

Testo completoClimate change is placing increasing pressure on forests around the world, and its potential impacts on the reproductive capacity of individuals are yet poorly understood. Many forest tree species reproduce following so-called masting patterns, in which seed production is intermittent and synchronized among individuals, whose drivers need to be identified in order to better understand the impact of climate on the fecundity of forest trees. The general objective of this thesis is to deepen our knowledge of the environmental drivers of the fecundity of forest trees and their interactions, by focusing on the holm oak, a widespread species in the Mediterranean basin. It also aimed to determine how fecundity could be impacted by climate change, and to develop a process-based model capable of predicting this impact. This thesis work combines analyses of long-term monitoring in a holm oak forest exposed to a rainfall exclusion experiment, experimental manipulations of source-sink interactions involved in the resource allocation to reproduction, and modelling. I have shown that reproduction was strongly regulated by weather conditions during the reproductive cycle and in particular by the water availability in summer-autumn, and to a lesser extent by the availability of carbon and nutrients, as well as by competition between fruits and new buds. My experimental results show that the allocation of resources to reproduction could be modified in case of resource limitation due to defoliation; and that developing fruits have a negative impact on the dynamics of nitrogen and zinc reserves in branches, as well as on the production of female flowers the following year. Long-term observations show that multi-year rainfall reduction induce a decrease in the number of fruits produced which is additional to the interannual variability and that tree reproduction does not acclimate to drought. Finally, within the PHENOFIT model, I have developed a fecundity model based on the assumptions and results from my work and from the literature

Testo completoThe non-pathogenic SlVagm infection in African Green Monkeys (AGM) is associated with high viremia as observed in pathogenic HIV-1 and SlVmac infections in humans and macaques. However, AGM display lower viral loads in lymph nodes and lack of signs of aberrant and chronic generalized T cell activation. In primary HIV-1 infection in humans, T cell activation levels determine the rate of disease progression. We raised the hypothesis that AGM do not develop AIDS due to (i) the absence of viral dissemination from myeloid dendritic cells (mDC) expressing DC-SIGN (CD209) to CD4+ T cells in lymph nodes and/or due to (ii) a rapid control of T cell activation decreasing the pool of target T cells and preventing the loss of CD4+ T cells. This study shows that the capacity of DC-SIGN from AGM to capture and transmit HIV/SIV is not linked to levels of viral load in lymph nodes and suggests that others factors such as levels of T cell activation might explain thé different profiles of viral replication in lymph nodes between pathogenic and non-pathogenic HIV/SIV infections. The study of SlVagm infection revealed an early induction of an anti-inflammatory environment (TGF-p, Foxp3) at 24 hours after infection followed by a strong IL-10 response in plasma. In contrast to SlVagm infection, this induction is delayed during primary pathogenic SlVmac infection. According to our data, the early response in anti-inflammatory cytokines that correlates with the induction of regulatory T cells might play a crucial role for preventing the harmful chronic T-cell activation observed during pathogenic HIV-1/SIVmac infections. 1624 caractères espaces compris receptor that ultimately accounts for virus internalization.

Testo completoOf the many pests that plants face, aphids are certainly the most damaging to crops due to their rapid multiplication, the direct damage they cause and the plant pathogenic viruses they transmit. The green peach aphid (Myzus persicae, Sulzer) is a generalist pest that attacks a wide range of plants including peach, its primary host, but also numerous secondary hosts from various botanical families including different cultivated species. Previous work has highlighted peach accessions with resistance to M. persicae conferred by the Rm locus that was characterised by an antixenosis phenomenon that rapidly causing the aphids to leave. The objective of our study was to identify, using an integrated transcriptomics and metabolomics approach, the factors involved in the expression of resistance to M. persicae in peach trees in order to obtain a quasi-exhaustive description of the biological functions activated or repressed by the infestation. We compared the responses to infestation of two peach genotypes, GF305 susceptible to M. persicae and Rubira carrying the Rm2 resistance gene, 48 h post-infestation, a period corresponding to the effective establishment of Rm2-induced resistance.Comparative transcriptomic and metabolomic analysis of the two peach varieties revealed a very limited response of GF305 to infestation while profound reconfigurations in Rubira were observed. The transcriptional reconfiguration resulted in a repression of genes involved in growth and development functions and an overexpression of defence genes, indicating a reorientation of cell function towards defence. This observation was confirmed by the significant reduction in metabolic pools of carbon, nitrogen and sulphur and by the accumulation of caffeic acid conjugates with anti-appetent or toxic properties towards aphids. Among the defence genes, the overexpression of PRR and NLR receptors suggested a joint activation of both branches of the plant immune system, PTI and ETI. Furthermore, the enrichment of oxidative stress-related genes, coupled with the activation of H2O2-generating metabolic pathways such as photorespiratory glyoxylate synthesis and P5C/proline futile cycle activation, underlineed the probable involvement of ROS synthesis in Rubira resistance to M. persicae. The appearance of necrotic lesions indicative of a hypersensitive reaction could also be attributed to an oxidative burst in response to infestation. The triggering of an acquired systemic response was also suggested by the activation of salicylic and pipecolic acid metabolism. Finally, as the involvement of pipecolic acid in plant resistance to aphids is poorly documented and in order to determine the role of this compound in peach resistance, the effect of an exogenous supply of pipecolic acid on the escape behaviour of M. persicae and on the development of aphid colonies, as well as on the metabolic profile of the apices was investigated. Although this experiment did not show the capacity of pipecolic acid to induce resistance, it provided new informations concerning the metabolic markers inducible by this molecule. To conclude, this work illustrates the extent and complexity of the expression of resistance to M. persicae conferred by Rm2 and underlines the interest of integrating transcriptomic and metabolomic data for the analysis of the plant/aphid interaction. This functional knowledge will be crucial in order to exploit natural sources of resistance and sustainably control aphid populations

Testo completoThe aim of this study is to measure the growth stress indicators (GSI) of the wood of grown Eucalypti and holm oak and to determine the technological properties for the valorization of these two species in the form of glued wood. Three trees of grown Eucalypti and holm oak were studied. Tensile specimens with massive wood and glued wood (end to end and in bevel), and DCB specimens with massive wood and glued wood were prepared. The quality of the assembly is treated by a probabilistic model based on the Weibull's statistical approach permitting to predict the reliability of the glued systems. The GSI, measured in the periphery of the trees, characterize the state of the wood formed in the very last years. The GSI distribution revealed generally that these two species have different behaviours. The grown Eucalyptus and the holm oak present a high nervousness. These obtained characteristics allowed us to classify them in a hard to half-hard wood, nervous, of strong shrinkage and an average rigidity. The massive wood presents a brittle behaviour with a fracture stress of the holm-oak twice bigger than that of the grown eucalyptus , although the glued wood (end to end or beveled) presents a ductile behaviour with a fracture stress almost the same for these two types of assembly. The Weibull coefficient m of the massive wood of these two species is weaker than that of the glued wood. The measurement of the restitution rate of the energy (toughness) of the massive wood and glued wood of grown eucalyptus and holm-oak has been experimentally achieved using the compliance method. The massive wood of these species is stronger than the glued wood. This latter has a higher toughness than that of the glued polyurethane. The average value of the experimentally determined toughness is very close to that calculated by the finite element code CASTEM 2000, which is greater than those found by ASTM and two embedded beams methods. In the massive wood, the crack initiates in the plan of low strength and the types of fracture observed during its propagation are intercellular and transcellular. In the glued wood the crack starts in the glue joint for the holm-oak, and both in the glue and wood for the grown eucalyptus. Whereas, its propagation is always adhesive for the holm-oak and mixed for the grown eucalyptus (alternately in wood and glue)
