When Pseudomonas is attacked, it strikes back!
Outer membrane damage triggers a tit-for-tat T6SS retaliation via TagQ/TagR protein complex assembly, activating the PpkA kinase.
Congrats to Maxim & team for uncovering this fascinating mechanism!

Proud and excited to share our first preprint 🚀 in which we
• create a high-fitness firewalled organism,
• that stably colonizes the mouse gut for >100 days,
• resists all tested phages in the gut,
• and blocks horizontal gene transfer.
+ Chimera genomes to tailor synthetic
