Genetic plasticity meets DNA repair heterogeneity
December 2021
Variation in DNA repair protein expression leads to differences in mutation rates between cells. Article now published in Nucleic Acids Research: Cellular heterogeneity in DNA alkylation repair increases population genetic plasticity.
Claire Qu
June 2023
Welcome to Claire Qu for her summer internship funded by the Lister Institute.

Welcome to Fiona Sargison who moved from Edinburgh to start a postdoc in our group.
DNA-target search
February 2021
Our new article in Molecular Cell shows that the bacterial chromosome is crowded with non-specifically bound proteins. Transient non-specific DNA binding dominates the target search of bacterial DNA-binding proteins.
LexA and the SOS response
June 2021
Bacteria sometimes induce the SOS DNA damage response even in the absence of stress. Why this happens and other findings revealed by a single-molecule tracking approach described in our new paper in Nature Microbiology. Free access: Imaging LexA degradation in cells explains regulatory mechanisms and heterogeneity of the SOS response.
DNA organization - replication - segregation
August 2021
Interplay between chromosome organization and replication fosters non-random inheritance of genetic material. Article now published in PNAS: Non-random segregation of sister chromosomes by Escherichia coli MukBEF.
Colworth Medal Lecture
April 2021
Watch Stephan's award lecture for the Biochemical Society Colworth medal on youtube: Seeing DNA repair and mutagenesis in bacteria.
#FEMSmicroBlog: Exposing bacteria molecule by molecule
August 2021
Amy Moores explains on the #FEMSmicroBlog how single molecule localisation microscopy techniques are playing important roles in bacteriology.
Under the Lens
We are running a journal club with other groups at Oxford, where we take recent papers on Microbial Imaging "Under the Lens". This goes together with a new regular feature in Nature Reviews Microbiology. More details can be found here.
DNA repair and evolvability
May 2021
This preprint investigates the phenomenon of stress-induced mutagenesis: Cellular heterogeneity in DNA alkylation repair as a trade-off between cell survival and genetic plasticity.

DNA-target search
August 2020
How do DNA-binding proteins find their target sites within the dense chromosome meshwork? New preprint describes a chromosome degradation method to address this question: Transient non-specific DNA binding dominates the target search of bacterial DNA-binding proteins.
Review article in Biochemical Society Transactions
March 2020
Our views on the origins and consequences of "Bacterial phenotypic heterogeneity in DNA repair and mutagenesis" are now published!
