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🧵

Thrilled to see this article out! 🎉 It's a roadmap for starting microbial ecologists with key concepts in community ecology, their history and application to microbiomes #NicheTheory #TrophicLevels #KeystoneSpecies #Succession #Metacommunities 🤩 What I wish I'd had when I got into microbial ecology

Oliver Meacock@olimeacock.bsky.social · 5mo ago

Delighted to see this out in its final form! doi.org/10.1093/isme... We established a discussion group focussed on the history of community ecology and how it informs our understanding of microbiota. This review distils those discussions to provide a guide for microbiologists entering the field

Check out our pre-print led by the fantastic Massimo Amicone, collaborating with the Bollenbach lab! tinyurl.com/4h9p8mfb We build a simple intuition on how ecological interactions affect resistance evolution by expanding evolutionary rescue theory and testing it with two large sets of experiments

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. 👏🏻🎉
