Corné M.J. Pieterse speaking for all of us! #2025ISMPMI

Celebrating 5 days of science at #ISMPMI2025 with my colleagues from @envgenlab.bsky.social @anmaylin96.bsky.social @ruhansen.bsky.social @Leonhard and @Eva 🎉🌾🍄

To wrap up…! Why keep an effector the plant can recognize? Our postdoc Liz Florez shows Z. tritici’s effector AvrStb6 shapes the wheat microbiome, esp. Pseudomonas spp., in susceptible cultivars. A hidden microbial modulation role beyond host recognition? 🗓️ Poster P-166 🔗 doi.org/10.5281/zeno...

How does heat reshape plant immune responses? Our PhD student Anica Schmauch shows higher temperatures boost ROS bursts in barley and potentially affect Z. passerinii growth, revealing abiotic-biotic cross-talk in disease resistance. 🗓️ Poster P-424 #2025ISMPMI

What makes wild wheat resistant to domestic Zymoseptoria? Our PhD student Rune Hansen found wild wheat relatives that stop infection by domestic Zymoseptoria at the stomata, with a pool of candidate genes that could potentially boost resistance in domestic wheat. 🗓️ Poster P-015 #2025ISMPMI

3rd day of #ISMPMI2025, means poster présentation day 😌

🌿 Curious about microbiomes, effectors, resistance genes, and temperature stress? Come meet our team at #2025ISMPMI We’ll be presenting posters all week on Zymoseptoria–plant interactions, wild relatives, and immune manipulation! 🧵 Thread with posters & schedule ⬇️

How does mowing and grazing shape the leaf and root microbiome of a wild grass? Our PhD student Eva Tanneau tracked 3 years of Agrostis capillaris microbiomes and found striking shifts under different management regimes, including pathogen emergence in leaf networks. 🗓️ Poster P-303 #2025ISMPMI

Can fungal pathogens manipulate the plant microbiome to aid infection? PhD student Leonhard Pachinger shows Z. tritici expression of killer-like protein effectors KP-4 & KP-6 that inhibit apoplastic bacteria, suggesting a microbiome-targeting strategy during infection. 🗓️ Poster P-217 #2025ISMPMI

Can fungal pathogens hijack host signaling peptides? Our PhD student Maxim Faroux @molecularmax.bsky.social uncovers a Zymoseptoria KEX2-processed effector putatively mimicking the plant hormone peptide phytosulfokine (PSK) known to lower immunity against hemibiotrophs. 🗓️ Poster P-226 #2025ISMPMI

Excited to present my poster (P-226) tomorrow at #ISMPMI2025. Looking forward to nice scientific discussions!

Being a plant biologist also means loving plants. Since phytochambers are not affordable for private use, nothing better than a DIY greenhouse full of #amorphophallus

Found a small grass (or ringed) snake (natrix natrix) 🐍

Northern Lights in Kiel on October 10th. Nature is amazing 🌃
