The evolutionary significance of synonymous variations: Can codon usage preferences drive the propagation of antibiotic resistance?

Objective

The intensive use of antibiotics provided an unprecedented improvement in infectious disease treatments but at the expense of creating ideal conditions for the selection of widespread resistance. Propagation of antibiotic resistances is favoured by horizontal gene transfer and by bacterial life in multispecies community. However, compositions of resistome and bacterial communities are often correlated, suggesting that propagation of resistances does not occur at random. This project will test the hypothesis that mismatch in codon preferences between the transferred genes and the receiving genome is a fundamental factor shaping resistome structure and evolution. Such central role of codon preferences may have been hitherto overlooked. The project combines mutant collection characterization, experimental evolution approaches –one in a multispecies context and one in a variable environment context-, full genome sequencing of evolved populations, phylogenomics and mathematical modelling integrating the experimental results of the other approaches, and generating a predictive tool about the evolutionary outcome of various real-life situations.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

ERC-COG - Consolidator Grant

Host institution

CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE CNRS
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.

€ 1 992 366,00
Total cost

The total costs incurred by this organisation to participate in the project, including direct and indirect costs. This amount is a subset of the overall project budget.
