Main topic

Gall wasps are insects capable of inducing structures called galls providing shelter against antagonists and varying climatic conditions, as well as food for their progeny, thereby increasing their survival. They do it by manipulating their host plant gene. The genetic basis of the ability to induce or form galls, on different plant species and organs, remains largely unknown and poorly studied. I used a mix of evolutionary approach to tackle this problem : population genomics, phylogenomics and transcriptomics.

Former/side topics

Cheese is a fermented food product that is the result of the transformation of milk by a
variety of microorganisms. Two Penicillium fungi are used for the maturation of cheese :
* Penicillium roqueforti, the blue mould, used for producing blue cheese
* Penicillium camemberti, the white mold, used for the production of Camembert-type
We use comparative genomics to understand the genetic basis of parallel adaptation of these two species to cheese.
We also use population genomics to unravel the history of domestication of Penicillium roqueforti.

Evolution and Development of left-right asymmetry

Asymmetric organs are found in many organisms, but it is unknown how they evolve de novo and what developmental and genetic processes or pathways change to derive asymmetry. This project aims to uncover the evolution of left-right asymmetry by studying the asymmetric male genitalia of Drosophila pachea that have a pair of external asymmetric appendages, or lobes with the left lobe being about 1.5 times longer than the right lobe. This asymmetry is only observed in D. pachea, it is absent even in closely related sister species, and must have evolved within the past 3-6 Ma. In addition, this species adopts a characteristic right-sided copulation posture. We use a combination of functional genetic approaches (transgenic flies, CRISPR/Cas9 mutants), time-lapse microscopy and behavioral studies to address questions related to the developmental changes that underly left-right asymmetry, its evolutionary origin, and evolution of mating behavior.

Sujet de thèse : Mécanismes impliqués dans les transferts horizontaux de matériel génétique chez les insectes

Cette thèse se divise en trois axes :

  • Etude de l’influence de la sympatrie sur les transferts horizontaux d’éléments transposables entre insectes
  • Les virus comme vecteur de transfert horizontal d’élément transposable enter papillons
  • Caractérisation des transferts horizontaux de cercles d’ADN d’une guêpe parasitoïde dans le génome de lépidoptères cibles et non cibles
