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.
#2025ISMPMI

After a refreshing break in the Eifel, I’m also heading to #2025ISMPMI Excited to meet all the friendly faces again and dive into some amazing research.
Come find us at posters P-364 & P-070 to chat about SCARs and their role in plant susceptibility. Let’s talk science! 🌱🧬

That’s amazing Manu. Congratulations!! 🥳 Will I have the opportunity to say this soon to you in person at the MPMI meeting?

Plz repost. Fresh Preprint led by @alexguyon.bsky.social
When a pathogen pushes into a cell already occupied by a symbiotic fungus, things change. New membrane phospholipids at pathogen haustoria! This may impact immune receptor positioning & defense secretion. -
And the roots are more resistant!

This is the amazing work from the super talented @alexguyon.bsky.social. Always loved to see your images in the seminar. Huge congratulations for finalizing the manuscript. Looking forward to reading it!

90% of you probably don’t need to read this.
But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy.
It’s about sharing something hard to say out loud;
partly to heal, partly in case someone needs to hear it too. (1/3)

Changes to the 2026 and 2027 Work Programmes With the launch of the competitions for grants under ERC Work Programme 2026 in July of this year, several changes to the submission of applications and the evaluation of proposals will apply. The mai...

Important changes on @erc.europa.eu grants‼️Grant structure & most importantly eligibility timeframes (10 years for starting, 15 years for consolidator post PhD-but you can have them only once) changes: erc.europa.eu/news-events/...

Meristems shape plant architectures, and grasses generate a complex array of them. To characterise barley vegetative SAMs and spike development, we used single cell and spatial transcriptome data and integrated them in a new database, BARVISTA. A click on a cell now.....

🤯 Look at this confocal image of a endomycorrhiza fungus inside a 400 million old fossil plant. Check out the new preprint by Christine Strullu-Derrien, @dromius.bsky.social and Ray from @slcuplants.bsky.social www.biorxiv.org/content/10.1... for more pictures and a video. Congratulations 🎉

Trichomes on an Arabidopsis thaliana leaf (here shown using electron microscopy) are formed by a single cell adopting this spiked shape (top images). Arabidopsis plants without a SCAR/WAVE gene cannot form properly shaped trichomes, because their inner cytoskeleton control is impaired (bottom images). Images by Sabine Brumm.

@binebrumm.bsky.social, together with @dromius.bsky.social team colleagues, unveiled how key proteins act as 'sculptors' in plant cells, taking on different roles to shape development

Now onto writing up the first chapter of our parallel project—diving deeper into SCAR functionality and investigating whether SCARs are conserved susceptibility factors in monocots. Stay tuned for what's next! 🌾🦠 🧵3/3

Huge thanks to the editor and reviewers for their constructive feedback and for helping us improve the manuscript. Grateful for the support and insights from everyone that shaped the final version. 🧵2/3

Functional divergence of plant SCAR/WAVE proteins is determined by intrinsically disordered regions Intrinsically disordered regions in SCAR/WAVE proteins drive diverse functions in root hair and leaf trichome development.

Excited to share that our preprint has found a home in Science Advances. We show that intrinsically disordered regions determine the functional diversification of actin-regulatory SCAR proteins in Medicago. 🧵 1/3

Congratulations to all of you. It’s amazing to see how everything came together and you already impressed the jury. I am sure the other visitors will love the exhibit as well.

You realize that you spend too much time on the microscope when the laboratory floor starts to look like microtome sections 😅

Microscopy Wednesday: Preparing for a practical course on Friday. Students will have to look at sporangiophores/sporangia of different oomycetes. #PlantScience #PlantMicrobeInteractions

If you are member of the IS-MPMI society, you will have received the option to vote for the next president and members of the board of directors. This is an encouragement to vote. Also, I am running for one of the two director positions.

I had some absolutely incredible papers come online this week, and I need to take a minute to post about each of them. First, let me tell you about the CarboTag probes for imaging plant cell walls! From the Sprakel lab (a short thread) www.nature.com/articles/s41...

🚨Check out this amazing finding: Inactivation of a symbiosis-specific Glucan binding protein leads to increased nitrogen fixation in Medicago. Amazing work, congratulations to everyone!

Over the next few months, my focus will be on securing funding for my future research team and finalizing my manuscript on SCARs and susceptibility in barley—finalising work from my time at Cambridge. Excited for what’s ahead! 🔮 🧵 5/5

I’m excited about the prospect of guiding a team of curiosity-driven researchers to explore the dynamic regulation of protein transport in plant-microbe interactions, particularly the polarisation of secretory trafficking towards the invasion site. Ultimate goal: enhancing crop resistance 🌾 ⚕️🧵4/5

The first 2 months have been about teaching and finding my footing, as the international move back (thanks to Brexit 🇬🇧➡️🇩🇪) came with its own set of challenges. That said, my new colleagues have been incredibly welcoming, guiding me through the transition and helping me find my rhythm once again🧵3/5
