Editor’s Pick! The cassava pathogen Xanthomonas phaseoli pv. manihotis (Xpm) causes severe disease, but its effector functions are not well understood. ‪‪Diana Gómez De La Cruz‬ et al. show that the Xpm effector XopAE suppresses plant defenses. Learn more: doi.org/10.1094/MPMI...

B, Formation of gall-like structures on hairy roots. C, Sss sporangia stained with trypan blue observed in root hairs 4 weeks post-inoculation. D, Sss sporangia stained with trypan blue observed in the cortex of hairy roots 8 weeks post-inoculation.

A breakthrough for potatoes: Samodya K. Jayasinghe et al. identify salicylic acid as a key defense hormone against Spongospora subterranea f. sp. subterranea, a persistent soilborne protist threatening yields around the world. 🥔

Great talk by @teamthomma.bsky.social who shows that effectors have antimicrobial activities that are ancesteral - other functions within the host have evolved later on to suppress immunity in plants #2025ISMPMI

The closing talk is being delivered by Maria Harrison. Maybe showing my Cornell bias, but her work is amazing as is her mentorship (so I’ve heard).

Maria summarizes the progress and current state of the field of arbuscular mycorrhizal fungi: “the most important symbiosis in the world”.

Maria Harris closing #2025ISMPMI with the "most important plant-microbe interaction on earth".
CKL1 and CKL2 kinanses locate to the periarbuscular and plasma membranes during AMF symbiosis and their kinase activity is key for regulating downstream lipid biosynthesis.

@ajbogdanove.bsky.social closes out #2025ISMPMI with praise of collaboration, the great questions, and the excitement for the field.

Reminds that the “Rewind” option will allow folks to watch missed talks - watch your email.

Big thanks to local organizers, the program committee, and society staff!

#2027ISMPMI - Try 2 for Jeju, Korea!

Hope to see you there and I’m glad that South Korea gets to host after their turn was missed because of the pandemic.

There is a promise of good food 🤤

Though I may need to start saving up now with the state of things…

Had such a great time at Colonge #2025ISMPMI
See you all next time! 🤗🤗

Trip to Heidelberg during the free afternoon — what a beautiful city! 🏰✨ #2025ISMPMI

On my way to the airport after an incredible few days in Cologne. So many inspiring sessions, great conversations, and brilliant people. 🌱🔬🫂 #2025ISMPMI

What a week! I’m happy to be a part of #2025ISMPMI, for all the wonderful people I met and discussions I had. Many thanks to everyone for sharing their research and to the valuable insights. 🌱🔬

We (@manuelgonzalezfuen.bsky.social @margotraffeiner.bsky.social @shanshuo.bsky.social) had a fantastic #2025ISMPMI in Cologne with lots of amazing science and great networking meeting old friends and new ones. Hope to see you all next time in Jeju/South Korea #2027ISMPMI

The Plant-Microbe Interactions group of @cornepieterse.bsky.social was well represented at #2025ISMPMI. Great to see all the interesting work that they do during one of the final presentations. @svanwees.bsky.social, @rlberendsen.bsky.social, @arsheed-sheikh.bsky.social #plantscience

Congrats to Niels Gallas, from Thomas Lahaye's lab @zmbp-tuebingen.bsky.social, for winning the Top Poster Award at #2025ISMPMI Well done!
🥳🥳🥳

Yesterday, the #2025ISMPMI wrapped up with an inspiring talk by Maria Harrison(@cornelluniversity.bsky.social), member of the External Advisory Board of CBGP, on AM symbiosis in land plants and its impact on crop production.

An amazing week of plant-microbe science with the CBGP delegation! 🌱🧬
