Mutations are fundamental for adaptation, evolution and antimicrobial resistance (AMR). Our previous work shows that high-density bacterial populations have lower spontaneous mutation rates (Krašovec et al., Nature Commun., http://doi.org/skb; Krašovec et al., Plos Biology, http://doi.org/cb9s), a phenomenon dubbed density-associated mutation rate plasticity.
We recently discovered that the negative relationship between mutation rate and population density arises from the collective ability of microbial populations to control hydrogen peroxide (Green et al., Plos Biology, http://doi.org/m8zt). Importantly, the reduction in mutation rate in denser populations is restored in peroxide degradation-deficient cells by the presence of wild-type cells in a mixed population.
The project will test the overarching hypothesis that mutation rate is a dynamic trait shaped by bacterial community composition. The aim is to quantify mutation rates in mixed communities composed of aerobic and/or anaerobic bacterial species and determine how composition of the community modifies mutation rates and mutational spectra. The candidate will quantify mutation rates with fluctuation tests or advanced super-resolution microscopy.
This timely project will greatly advance the fundamental understanding of mutation rates in mixed communities. It is also medically important because understanding the mutation rate of the community may help in identifying mechanisms that promote or hamper emergence of AMR.
Main responsibilities
This is a 30-month full-time position aiming to start in December 2024 (negotiable).
The ideal candidate is an outstanding experimentalist who holds (or expects to hold shortly) a PhD (or equivalent) in microbial evolution, microbial ecology, microbiology or related fields.
They should have excellent technical skills in the lab, extensive and up-to-date knowledge in evolutionary microbiology, mutagenesis and DNA repair and a keen interest in live fluorescence microscopy and microfluidics. Enthusiasm for the project and a strong interest in crossing research fields are essential.
The successful candidate will carry out microbiology protocols, a cutting-edge microfluidics and live single-molecule localisation microscopy, fluorescently label bacterial proteins and regularly interact with enthusiastic team of outstanding scientists in Rok’s group and widely in MERman https://sites.manchester.ac.uk/merman/
