Effect of Arbuscular Mycorrhiza establishment on the genetic structure and functionality of bacterial communities in the rhizosphere of Medicago trun…

2007

Bacterial communities associated with (i) M. Truncatula J5 (Myc+/Nod+) and TRV48 (Myc+/Nod-), and with (ii) M. Truncatula TRV25 (Myc-/Nod-) were compared. The genetic structure of communities was characterized with an A-RISA DNA fingerprint. The genetic structures of communities associated with mycorrhizal and non-mycorrhizal roots were significantly different. Bacteria belonging to the Oxalobacteraceae and Comamonadaceae families were preferentially associated with mycorrhizal roots. The genetic diversity of cultured bacteria belonging to these groups was analysed by BOX-PCR. The diversity of isolates from mycorrhizal and non-mycorrhizal roots was significantly different. The functionality…

Déterminisme génétique de la composition protéique des graines de légumineuses et de sa plasticité vis-à-vis de l’environnement

2018

Les légumineuses sont capables de produire des graines riches en protéines sans apport d’engrais azoté grâce à la symbiose racinaire avec des bactéries du genre rhizobium. Riches en lysine, ces protéines sont utilisées pour l’alimentation des animaux d’élevage et en nutrition humaine. Afin de promouvoir la culture des légumineuses, il est nécessaire d’optimiser et de stabiliser la qualité de cette fraction protéique. L’objectif de ma thèse est de mettre en évidence les déterminismes génétiques sous-jacents à la teneur et à la composition protéique des graines de légumineuses ainsi qu’à la plasticité de ces composantes vis-à-vis de l’environnement. Afin de répondre à cet objectif, l’approche…

Identification of sugar transporters in arbuscular mycorrhiza, from basic to applied science

2012

Our study focuses on sugar transporters from both plant and fungal partners at the symbiotic interface to better understand biotrophic exchange systems. Thereby, a collection of putative contigs and ESTs of hexose transporters from Medicago truncatula and Fragaria x ananassa will be processed. The full length sequences will be cloned for functional complementation and uptake experiments in transport deficient yeast mutants. This work also investigates the influence of different mycorrhizal fungi on (1) the expression level of sugar transporters and (2) the economically relevant part of F. x ananassa by analyzing its impact on the plant and the fruit. To this aim, combination of phenological…

Effet de la nutrition et du génotype sur les réponses de défense chez Medicago truncatula

2014

Les organismes phytopathogènes sont responsables de la destruction d’environ 30% des récoltes. Malgré leur impact négatif sur l’environnement et la santé humaine, les produits phytosanitaires restent un des principaux moyens de lutte. Dans un cadre général de diminution de l’utilisation de ces produits, mon projet de thèse a pour objectif de mieux comprendre l’effet de la nutrition de la plante et de son génotype sur les mécanismes moléculaires impliqués dans ses réponses de défense vis-à-vis des pathogènes et ceci afin de définir des stratégies de lutte innovantes. Etude de l’effet des carences nutritionnelle sur la signalisation cellulaire et moléculaire des réponses de défense par analys…
