New preprint!

Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠

Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

An epic effort by Rosanna Wright

Resistance mutation supply modulates the benefit of CRISPR immunity against virulent phages
Only a fraction of bacterial genomes encode CRISPR-Cas systems but the selective causes of this variation are unexplained. How naturally virulent bacteriophages (phages) select for CRISPR immunity has...

Our latest paper is out with @adiop.bsky.social and @gmdouglas.bsky.social. We analyzed the extent of homologous recombination between bacterial species (introgression) and how it affects species borders (it can vary a lot depending on the approach used to classify species!). rdcu.be/eQAMf
Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy
Nature Communications - It is commonly thought that bacterial species borders tend to be fuzzy, due to frequent exchange of DNA. Here, Diop et al. quantify the patterns of gene flow between core...
