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...

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?

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...

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
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.

Two M. tuberculosis RelE toxins don’t cut mRNA, they slice 16S rRNA itself, shutting down translation in a totally unexpected way, new study reveals.
A big leap in understanding TB’s survival tricks and new angles for therapies.
