Full textThe global shape of an ornamental plant is one of its major aesthetic criteria. It is controled by its architecture, particularly by bud bursting and shoot elongation. Environmental factors including light have a strong impact on both processes. The management of the lighting conditions during plant culture could help to produce plants with innovative shapes, using environmentally-friendly practices. However, there is a significant lack of knowledge about the mechanisms involved in the regulation of plant development by light. In this thesis, we studied the effect of blue light on the architectural development of two varieties of rose bushes coupling morphological, histological and molecular approaches. Our results show that monochromatic blue light has a depressive effect on the photosynthetic assimilation of roses but induces in both cultivars, same meristem organogenetic activity, internodes growth and floral development than full spectrum light. On the contrary, the removal of blue raies from white light stimulates the elongation of the first order axis in one of the two studied cultivars. This stimulation results from the increase of leaf photosynthetic assimilation and internode cell elongation. This photo-control is exerted on the expression of genes involved in sugar metabolism and cell wall loosening. Our study of photoreceptor mutants in pea suggests that phytochrome B is the major photoreceptor involved in this response to blue light

Full textThis thesis is devoted to the study of the effects of light on a magnetic tunnel junction (MTJ). A MTJ is made of a nanometer thick insulating layer sandwiched between the two magnetic layers. When an electric current is injected into such a structure, a voltage can be measured across the insulating layer. This voltage depends on the relative orientation of the magnetizations of the two magnetic layers. This is known as the tunnel magneto-resistance effect. We have shown in this thesis that voltage depending on the orientation of the magnetic layers can be measured when the junction is illuminated with light. By studying the influence of the substrate, the position of the light beam, the wave length of light and the response of the system to a laser pulse, we have been able to demonstrate the presence of photovoltaic and Seebeck effects. These results show that it is possible, thanks to the sunlight, to read the information from magnetic memory (MRAM) made of a MTJ

Full textApplied in high doses, UV-C radiations are harmful, while administered at low doses, these same radiations stimulate beneficial answers. This phenomenon is known as hormesis and the beneficial dose is qualified hormic. The application of low doses of UV-C on fruits and vegetables in post harvest enhances resistance against pathogens (Charles et al, 2008), improve their nutritional quality (Mercier et al, 2001) and their performance to grow (Siddiqui et al, 2011). This works were carried out on different species. In my thesis, we treated a single species of romaine lettuce var claudius after harvest with a non-harmful dose of UV-C (0.85kJ.m-2) and we evaluated its effect on resistance to Botrytis cinerea (BC87) and Sclerotinia minor (SM), in their nutritional value during storage and their responses to salt stress. The analysis of all the results obtained showed that the UV-C dose decreases the sensitivity of romaine lettuce to these two pathogens (Ouhibi et al. 2014a), improve nutritional value by increasing the content in phenolic compound, in ascorbic acid and acquire to plants from seeds pre-treated with UV-C greater potential for adaptation to salt stress (Ouhibi et al, 2014 b)

Full textThis work is devoted to the study of the bacterial response of Pseudomonas and Enterococcus genus against Pulsed Light treatment (PL). First, the characterization of the PL decontamination unit has chosen a configuration for achieving uniform treatment and to know the physical characteristics. On the other hand, very rapid kinetics destructions of bacterial cultures are obtained in this configuration (reduction of 9 logarithm units a few seconds). In this study, we showed that Pseudomonas aeruginosa is usually more sensitive than Enterococcus faecalis with respect to the same intensity treatment. However and interestingly Pseudomonas aeruginosa is able to adapt to a lethal treatment LP when subjected to sublethal PL doses. While Enterococcus faecalis showed a mutation rate increased after treatment. These different mechanisms used by bacteria in order to cope with the deleterious PL effects were identified by two-dimensional electrophoresis analysis to elucidate the molecular mechanisms involved in these responses

Full textWe wanted to determine the nature of sucrose transport, isolate, characterize and localize one or more sucrose transporters (SUTs) and assess if these SUTs respond to defoliation or to a modulation of light intensity before and/or after defoliation in rye-grass. Sucrose transport is apoplastic. It depends on a multigenic family of SUTs that were identified for the first time in rye-grass (LpSUT1, LpSUT2). The functional characterization of LpSUT2, which possess a cytoplasmic inner loop, was also successfully realized for the first time in a Monocot species. LpSUT2 is inhibited by fructose, which is a remarkable result for a fructan-accumulating plant, thus suggesting that this SUT could be the perception site of a sugar signal. The expression and the localization of these SUTs, mainly in the mesophyll, suggest that they play a great role for the distribution of C resources within the regrowing plant. The LpSUT1transcript level increases in the few hours following defoliation and might be regulated by sucrose content. LpSUT1 could be implicated in the lateral sucrose transport associated to the storage and/or the mobilization of fructans. The LpSUT2 transcripts are not sensitive to defoliation, but they are surprisingly modulated by light intensity before and/or after defoliation, which could strikingly match their putative role of sugar sensors. Because neither LpSUT1 nor LpSUT2 are localized within phloem tissues, this suggest the existence of other SUTs. The present results allow to better understand regrowth mechanism within a perennial forage species accumulating fructans
