Repurposing of a DNA segregation machinery into a cytoskeletal system controlling cell shape Bacteria, like eukaryotes, use conserved cytoskeletal systems for intracellular organization. The plasmid-encoded ParMRC system forms actin-like filaments that segregate low–copy number plasmids. In m...

A WYL transcriptional regulator activates the DNA damage response pathway in Acinetobacter species Abstract. The ability to sense DNA damage and activate DNA damage response pathways is critical for repairing DNA damage in all domains of life. The most w

I am pleased to share my lab’s latest publication - Acinetobacter species lack canonical DNA repair pathway activation mechanisms, and we discovered a conserved transcriptional activator that fills this role: academic.oup.com/nar/article/...

Égalité dans le recrutement professoral : une dynamique encourageante À l’occasion du 8 mars, Journée internationale des droits des femmes, la Direction revient sur l’évolution du recrutement professoral à l’Unil au cours des trois dernières années. La part de femmes recrutées progresse nettement, même si atteindre la parité suppose un engagement constant dans la durée.

A single DNA methylation site regulates cell fate during Clostridioides difficile sporulation DNA methylation is a widespread phenomenon in bacteria that can regulate gene expression, although the mechanisms underlying this epigenetic regulation are often poorly understood. In Clostridioides d...

Widespread potential for phototrophy and convergent reduction of lifecycle complexity in the dimorphic order Caulobacterales - Nature Communications This study maps out the diversity and evolution of the bacterial order Caulobacterales, including the model organism C. crescentus, which reveals widespread phototrophy and illuminates the evolution o...

Excited to see our new work published! We have established the evolutionary and ecological context of our favorite model Caulobacter and made some unexpected findings.
Who would have thought that close relatives lack dimorphism? And have potential for phototrophy?

Comparative analysis of the Caulobacter SOS response under mitomycin-C damage. Top left: Schematic summarizing the RNA-sequencing experiment. Caulobacter cells were treated with 0.25 μg/ml mitomycin-C for 20 and 40 min (Created in BioRender). Samples were collected for transcriptomic analysis before (0 min, control), and at 20 and 40 min post damage induction. Top right: Venn diagram representing the genes that meet the listed criteria: 1. Genes induced in wild type cells under MMC damage at 40 min (white circle). 2. Genes induced in ΔlexA in the absence of damage (blue circle). 3. Genes not induced in ΔrecA background under MMC damage at 40 min (gray circle). Genes fulfilling all three criteria are in the gray circle. Number of genes in each category is indicated. Bottom left: Bar graph indicating whether promoters of the shortlisted genes exhibit binding by the LexA protein as assessed from ChIP-seq analysis [10]. Bottom right: LexA ChIP-seq profile for genes belonging to the SOS response. Normalized reads (in rpm) are represented for 500 bp upstream and downstream of the gene CDS.

The bacterial #SOSresponse unfolds in a defined temporal order, but how does this arise? @adityakamat.bsky.social @anjbadri.bsky.social &co show that intrinsic #promoter strength, modulated by #SigmaFactor usage, governs timing of SOS gene activation in Caulobacter @plosbiology.org 🧪 plos.io/4oAKf0Q
