Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature.
Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis.

Our paper on the YprA family of helicases and their roles in bacterial defence is now out!
We describe ARMADA, a defence system synergise with Druantia and show that both systems spread horizontally on a novel type of mobile genetic element that we call SPIDERs

CapK is a bacterial DNA damage-activated kinase that phosphorylates transcriptional repressor CapS to control adjacently-encoded anti-phage immune pathway genes in response to a universal stress signal, DNA damage

Bacteria and archaea possess an enormous variety of antiviral immune systems that often share homologous proteins and domains. YprA-family helicases a…
Bacteria encode numerous stress-response pathways that protect their hosts against both internal and external threats. A key question is how these pathways are regulated, especially anti-phage immune ...
The activation of an antiphage defence system relies on host factors targeted by phages, a mechanism analogous to the way that eukaryotic innate immune systems detect pathogen-induced perturbations of...

During the Archean Eon—roughly 4 billion years ago—the Earth was a lifeless planet. The atmosphere lacked oxygen, and there were few, if any, organisms to be found anywhere on the globe. Then…
