Myth busted: immune activation ≠ immunity 🌱⚔️. We found ETI can trigger full cell death without stopping bacterial growth - if water stays in the apoplast. Want to know what immunity is from a physiological standpoint? 👇 A thread🧵

Who would have thought, five years ago when I first looked at P-bodies under the microscope, that this journey would lead here. 🔬 Very happy to see this work finally out in #ScienceAdvances. Proud of this collaborative effort and grateful to everyone involved. 👏🏻🎉
