Texte intégralStructural Studies of the Pyoverdin Receptor FpvA from Pseudomonas aeruginosa. Pseudomonas aeruginosa is a gram negative bacteria involved in 10 to 20 % of hospitals infections. Its main targets are burnt and immuno-deficient patients, and people who have developped a cystic fibrosis disease. Its major iron acquisition system also involved in its infectious capacity, is based upon the pyoverdin PaA and its outer membrane receptor FpvA, a TonB dependant receptor. This thesis work intend to better understand the highly specific interactions between the pyoverdin and FpvA. In the first part, we studied many sequences of TonB-dependant receptors available in data banks, in order to identify importants regions of the proteins. The Förster resonnance energy transfer (FRET) abilities between the receptor and its ligand are also presented. In the second part, we used the time-resolved fluorescence spectroscopy technique to study the receptor-ligand interactions of the different FpvA-PaA in vivo and in vitro made complexes. The aim of this work is to understand how the bacteria makes a difference between all these complexes and translocates only the PaA-Iron one. In the third part, we established an efficient and fast process for the FpvA purification from the homologous over expression system in Pseudomonas aeruginosa. We started the 3D crystallogenesis experiments in order to resolve the 3D structure of the FpvA-PaA in vivo made complex. We obtained crystals diffracting at up to 2. 7 A at low temperature

Texte intégralSiderophores are strong iron chelators produced by bacteria under iron deficiency conditions. In the present work, we studied the impact of the siderophore pyoverdine, produced by the plant growth promoting rhizobacteria Pseudomonas fluorescens C7R12, on plant physiology from phenotypic to molecular effects with a specific focus on plant growth, immune response and iron homeostasis. Based on our analysis of the mode of action of the non-protein amino acid β-aminobutyric acid (BABA), a priming inducer in plants, we studied more specifically the functional link between iron homeostasis and plant immunity. Under iron deficiency, P. fluorescens excretes the iron free form of pyoverdine (apo-pyo) in the soil. Once chelated with iron (ferri-pyo), the complex is internalized by the bacteria. We demonstrated that Arabidopsis thaliana plants treated by apo-pyo in a medium containing or not iron (Fe 25 or Fe 0) also internalize pyoverdine. Moreover, we observed that under iron deficiency, pyoverdine treated plants did not display the growth reduction induced by iron deficiency. In accordance with this phenotype, a microarray analysis revealed that the expression of genes related to growth and development was induced, as well as genes related to iron uptake and transport in planta. In contrast, the down regulation of the expression of genes related to defense was observed. Correspondingly, we demonstrated that the growth improvement induced by apo-pyo under iron deficiency depends on the expression of IRT1 and FRO2, two major genes involved in iron uptake mechanisms. Of interest, the resistance to Botrytis cinerea conferred by iron deficiency was lost following apo-pyo treatment. The overexpression of the HBI1 transcription factor, known to be involved in the growth-defense tradeoff, can be linked to the above observations. These apo-pyo effects were not observed after treatment of plants under sufficient iron conditions, indicating that in A. thaliana apo-pyo effects are dependent on the plant iron status. In the same time, the analysis of the mode of action of BABA that potentiates plant defense responses demonstrated that BABA is a powerful iron chelator. BABA treatment in A. thaliana triggered a transient iron deficiency response. Based on this assessment, we assume that iron deficiency response and priming of defense may be connected. In accordance with this hypothesis, we showed that plants cultivated under iron deficiency and BABA treated plants both displayed resistance to B. cinerea and produced secondary metabolites associated to defense. Hence, the BABA priming effects on plant defense may be due to the induction of transient iron deficiency. To conclude, this work draws first explications on pyoverdine effects on plant physiology and presents an original mode of action contributing to the priming effects of BABA. In a larger view, this work supports the recent concept of the existence of a cross-regulation between growth, immunity and iron homeostasis in plants

Texte intégralConsidering its toxic effect on health, the use of asbestos has been banned in France since 1997. Currently, asbestos removal is a priority and we have to deal with huge amount of wastes. Only two treatments are in use, storage or transformation in glass by plasma technology. However, these methods do not eliminate the waste. The aim of this project is to explore various biological pathways in order to develop a biotechnical process to treat asbestos waste. This work showed for the first time that pyoverdines are able to solubilize iron from asbestos with various efficiency depending in pyoverdine structure. We highlighted that waste represent an iron and magnesium source for fluorescent Pseudomonas thanks to the use of siderophores for iron release and an unknown mechanism for magnesium. Moreover, the use of organic acids associated with bacteria allowed a huge extraction of iron and magnesium from asbestos waste, which is the best pathway to date
