Full textWater uptake by roots plays a central role in the regulation of plant water status. The root water permeability (root hydraulic conductivity; Lpr) is regulated by many environmental conditions such as drought or nutrient deficiency. At the molecular level, water channels named aquaporins contribute to a large part of the overall Lpr (> 70% in Arabidopsis thaliana). However, the mechanisms for aquaporin regulation in plants and their role in the modulation of Lpr by environmental stresses are still poorly understood. The aim of this thesis was to unravel novel molecular and cellular mechanisms of aquaporin regulation in the context of water transport modulation in the root of Arabidopsis. For this, Lpr regulation was studied in two distinct physiological situations, salt stress (NaCl) and exposure of roots to reactive oxygen species (ROS). Here we show that a salt treatment (100 mM NaCl) can inhibit Lpr by 35% in 40 min and by up to 70% after 3 h. Aquaporins expression was regulated in parallel to this at, at least, three levels : the abundance of transcripts and proteins and the subcellular localisation of the latter. Whereas these mechanisms may explain the long term (> 4 h) regulation of Lpr by salt, other types of regulation, by post-translational modifications for instance, might be involved in the early response (< 2 h) of the root. In another study, hydrogen peroxide (H2O2) and other ROS were identified as powerful inhibitors of Lpr by up to 80% in a few minutes. Unexpectedly, the action of ROS on the aquaporin activity was not mediated by a direct oxidation gating mechanism, but rather involved the activation of signalling pathways in which external calcium and protein kinases played an important role. From this and other works, we conclude that, as central molecules in the response of plants to environmental stresses, H2O2 and other ROS could be major regulators of Lpr. In conclusion, this work uncovered signalisation pathways and multiple levels for regulation of aquaporin expression which contribute to a chain of events from the perception of environmental stress to the molecular regulation of root water transport

Full textLn order to identify processes that act on herbicide isoproturon transfer in soil and water, several experimental studies were attempted. Ln the field, isoproturon appeared to reach surface soil water early after treatment. Then, the same soil was used to fill lysimeters placed under natural climatic conditions. Rainwater was able to produce large exportations only during the first month after treatment, because isoproturon, not yet fully degraded, was very mobile. Last, experiments under laboratory controlled conditions showed that isoproturon was sorbed only weakly on soil components. On the opposite, some of its degradation products, which rapidly represent the greatest part of residues, were more strongly held to soil

Full textThis thesis presents an experimental investigation on the propagation of nonlinear water waves. The first part focuses on the space-time measurements of nonlinear water waves, when it passes over a submerged step. The space-time resolved measurement allows us to separate the different components at the second order, which are compared with a theoretical nonlinear multi-modal model. The important contribution of the surface tension at higher orders is verified by measuring the beating length of the second harmonic. In the same conditions, the addition of a reflecting wall at the end of the channel sets a rectangular tank with submerged step, where the excitation of low-frequency modes yields a quasi-periodic dynamics. Concurrently, a research about aspects that have to be considered in small scale experiments of surface waves has been carried out. In shallow water, the damping of water waves is highly influenced by the bottom friction. This dependence was measured for randomly distributed waves, revealing the relative contribution of this effect. Moreover, the dynamic of the contact line plays a significant role when the wave-amplitude is small and the boundaries are near, both in relation to the capillary length. We observed experimentally how the wetting of the boundaries changes the reflection and the wave-front curvature. The final part covers the measurement of perfect wave absorption by a coupled resonator in a narrow waveguide. The trapped modes generated by a cylinder shifted from the channel axis were excited to generate the absorption

Full textModel milk powders were prepared by co-lyophilization of lactose and β-lactoglobulin and stored at various water activities (aw) to better understand interactions between the two components in a dehydrated state. The presence of β-lactoglobulin influenced the critical aw where physico-chemical modifications like non-enzymatic browning, particles caking and particularly lactose crystallization, occurred. Moisture sorption isotherms, differential scanning calorimetry and X-ray diffraction demonstrated that β-lactoglobulin can both delay crystallization and increase crystallization aw to 0. 54 and even 0. 59 in model powders containing 10 to 30%, and 40% β-lactoglobulin respectively, compared to 0. 43 for pure lactose crystallization. This stabilizing effect was due to the development ofboth covalent interactions and hydrogen bonding between lactose and β-lactoglobulin, as shown by non-enzymatic browning and spectroscopic studies. When model powders were stored at the aw just below their critical aw, preferential protein hydration occurred: hydrogen bonding between lactose and β- lactoglobulin decreased, whereas it increased between water and β-lactoglobulin. This change in hydrogen bonding seems to be responsible for the stabilizing effect against crystallization observed in model milk powders
