Stories of Salicylic Acid: A Plant Defense Hormone Salicylic acid (SA) is a key plant hormone required for establishing resistance to many pathogens. SA biosynthesis involves two main metabolic pathways with multiple steps: the isochorismate and the p...

For those who are not familiar with SA research history, we humbly introduce a review we wrote years ago: www.cell.com/trends/plant... @cp-trendsplantsci.bsky.social

Last week’s #2025ISMPMI and #OMGN2025 were really fun! My first conference visit in the field of plant microbe interactions, so I learned a lot (brain is still achy)! I’m grateful to @dromius.bsky.social for this opportunity and to the rest of the Schornack batch for awesome company!

Research Associate in Programmable Plant Immunity at Imperial College London Apply for the Research Associate in Programmable Plant Immunity role on jobs.ac.uk, the top job board for academic positions in higher education. View details and apply now.

Plz RT. We are looking for a postdoc to join our collborative project on AI-guided bioengineering of plant immune receptors @tolgaboz.bsky.social and @jiorgoskourelis.bsky.social labs: www.jobs.ac.uk/job/DNV032/r...

Aphid effectors suppress plant immunity via recruiting defense proteins to processing bodies Aphids hijack plant immunity via p-bodies, but plants fight back with a heat shock protein in an unexpected twist on defense.

Our paper is now online in Science Advances! Congrats @saskiahogenhout.bsky.social @johninnescentre.bsky.social and all coauthors!

#2025ISMPMI
Huge congrats to Sebastian Eves-Van Den Akker @sebastianevda.bsky.social on earning the Early Career Achievement Award for his outstanding research on plant-parasitic nematode infection biology 🎉🏆

With over 800 posters at #2025ISMPMI it might be tricky to find me. But here’s a little helping video.

Come today (Wednesday) between 13:30 and 15:15 to Poster P-425 to hear about #Marchantia #Phytophthora interaction and a GRAS transcription factor!

Fascinating talk by Dr. Talia Karasov (University of Utah) on how plant pathogens weaponize phage-derived tailocins to wipe out bacterial rivals.
Microbes fighting microbes—nature’s own biotech.

Three ARID proteins involved in chromatin remodeling PEAT complexes are targeted by the Ralstonia solanacearum effector PopP2 and contribute to bacterial wilt disease The Ralstonia solanacearum effector PopP2 is a YopJ family acetyltransferase. PopP2 is known to dampen basal immune responses by acetylating defensive WRKY transcription factors, and probably by targ...

Love uncovering effector virulence strategies! 😀
Our work on PopP2 targeting core components of the PEAT chromatin-remodeling complexes is now out @theplantjournal.bsky.social.

#2025ISMPMI
Benjamin Gourion elucidated the pathogenic molecular mechanism underlying a rare case of rhizobia transitioning from a symbiotic to a pathogenic interaction. Truly fascinating!

Sebastian Schornack @dromius.bsky.social kicks off the 'Microbial Infection Strategies' session with insights into symbiotic and pathogenic interactions in the vascular and non-vascular plants.

First batch of Team Schornack @dromius.bsky.social have just landed in Cologne for plant-microbe chat at #2025ISMPMI!

The latest publication from our lab!

The famous "glomalin" from arbuscular mycorrhizal (AM) fungi is not a protein but a polysaccharide from AM fungi, so we renamed it "glomalose". Glomalin-related proteins are bacterial proteins stuck in this glomalose.

Read & RP. New preprint by Alex Gavrin from his time in our team - Inactivation of Medicago Glucan binding protein 1 (GBP1) offers: An approach to enhance symbiotic nitrogen fixation.
www.biorxiv.org/content/10.1...

🚨 New preprint! Alex Gavrin & co. identify a symbiosis-specific GBP1 gene whose inactivation boosts nitrogen fixation - without altering nodule number or development.
A promising route to engineer more productive legumes!
🌱✨Congrats to all involved!

Thanks Jim 🙂

A pathogen effector FOLD diversified in symbiotic fungi Pathogenic fungi use secreted effector proteins to suppress immunity and support their infection, but effectors have also been reported from fungi that engage in nutritional symbioses with plants....

🎉 Thrilled to share that our article on the discovery of MycFOLD effectors in symbiotic fungi ranks among the most viewed papers in @newphyt.bsky.social in 2023! Grateful for the interest - Let’s keep the momentum going!
