Bacterial immune systems as causes and consequences of microbiome structure
Bacterial immune systems have evolved in response to diverse molecular "parasites", yet their ecological roles remain poorly understood. This Essay explores how interactions between mobile genetic ele...

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...

Mechanistically, incoming ssDNA is a game changer: it promotes attC site folding, triggers integrase expression via SOS, and allows cassette excision without the need for replicative resolution. This suggests both intra- and inter-bacterial shuffling shape integron recombination dynamics. 4/5

Excited to share some new work led by grad student Sophie Walton (w/ @petrovadmitri.bsky.social). We used in vitro gut communities to study how natural selection acts on strains of the same species as they compete within larger communities. Check out Sophie's thread below for details!
Super excited that the bulk of my PhD work is now preprinted! Here we used whole-community competition, or coalescence, experiments to quantify selection acting on genetically diverged strains within larger communities. (1/n)

NSF’s doors will be closed at 1:30 pm today. While you may be able to submit things, there will be no staff to process anything. In fact it is illegal for us to even open our work computers or email during a shutdown. A very few rotators may be able to communicate, so check out of office responses.
