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)

Last year it was discovered that a single bacterial NLR-like protein can recognize multiple, structurally unrelated phage proteins (Béchon et al, Kibby et al)

Now, a new study shows the same for a plant NLR. Another example how principles of immunity remain conserved from bacteria to eukaryotes

PIWI clade Argonautes are essential for transposon silencing. Without them, animals are sterile due to massive transposon activity.

But how does piRNA-guided target interaction translate into silencing?

YprA is a helicase popping up in multiple defense systems. In our new preprint (led by Ryan Bell), we investigate YprA clades and describe new defense systems. Importantly, ARMADA II synergizes with Druantia III; and Zorya II, Druantia III, and ARMADA II often travel together on various MGEs.
