New preprint from @s-gauthier.bsky.social and @charlesrleveillee.bsky.social in collaboration with the labs of Xuifang Xin, @gittacoaker.bsky.social and Laurent Noël Water immunity: Yesterday's preprint: Dampness is a DAMP... today's: ...but it also dampens defense www.biorxiv.org/content/10.6...

Extracellular water withdrawal drives disease resistance in the phyllosphere
A central question in immunity is how hosts arrest pathogen growth. Diverse plant pathogens create a water-soaked niche in host tissue essential for pathogenesis, yet how water shapes infection outcom...

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🧵

New preprint. Effector-driven extracellular niche establishment (EDEN) involves water-soaking. We asked if apoplastic water accumulation has an effect on the plant immune response. @charlesrleveillee.bsky.social @s-gauthier.bsky.social @ilafores.bsky.social y.social www.biorxiv.org/content/10.6...

Atypical immunity induced by extracellular water in plants
Microbial pathogens require nutrients and water to support their growth and proliferation. Pathogen-mediated resource acquisition is orchestrated by the secretion of virulence factors that have evolve...

Do plants sense extracellular modifications induced by pathogens? New data suggests that yes. Water-soaking lesions activate atypical but functional immune programs, hinting at sensing mechanisms beyond canonical pattern recognition. First of two papers dropping this week. Read it on bioRxiv 🧵

@centre-seve.bsky.social The moffett lab now has a pichnotte board in our student office. Other labs better watch out the next JCS! We're coming for the pichnotte trophy

Now out in @newphyt.bsky.social from @charlesrleveillee.bsky.social. We investigated the link between induction of chloroplastic ROS and the production of SA in defense and its suppression by effectors, as well as the importance of ABA in this phenomenon nph.onlinelibrary.wiley.com/doi/10.1111/...
