OFFER DESCRIPTION

The post-doc will be responsible for monitoring tick cell lines, performing infection and co-infection and characterising the cellular phenotypes. Methods include RT-qPCR, dual-RNAseq, FISH combined with electron microscopy.

The objective of the project is to identify the evolutionary mechanisms that drive extinction and reborn of mutualistic interactions using ticks (Ixodida, Acari) as ideal biological models to address this question. Ticks host nutritional symbionts that are essential for their growth and survival, but the origin of these symbionts varies considerably between host species and substitution of beneficial symbionts can occur (Gottlieb et al, 2015; Duron et al, 2018; Guizzo et al, 2017; Duron et al, 2017; Binetruy et al, 2020).
The project aims at deciphering the competition between Francisella and Coxiella symbionts using different approaches from genomics, transcriptomics, in vivo and in vitro imaging. The recruited post-doc will participate in this innovative program with a particular focus on in vitro experiments assessing the competitive abilities of the two beneficial symbionts.

The position is associated with the ANR-funded collaborative project MICROM “Microbial competition in mutualistic interactions with ticks”. The MICROM consortium, led by Olivier Duron, involves three teams (O. Duron MIVEGEC, Montpellier, F. Vavre LBBE, Lyon and D. Bouchon EBI, Poitiers) with considerable expertise in the field of endosymbiosis.
The post-doc will be part of the Ecology, Evolution & Symbiosis team of the EBI laboratory in Poitiers, which has a long experience in research on symbiosis. The post-doc will have access to the funding and infrastructures needed for this project, in a stimulating scientific environment. Regular exchanges and mobility are planned with the various project partners as well as with external collaborators such as the Tick Cell BioBank in Liverpool. At the CNRS, the post-doc will be under the responsibility of the project leader.
