Recruitment of bifunctional regulator thermospermine to methylated ribosomes directs xylem fate Polyamines are often associated with ribosomes and are thought to stabilize their integrity. In Arabidopsis, the polyamine thermospermine (tSpm) affects xylem cell fate. tSpm induces translation of SU...

We welcome anyone who wants to learn about clubroot disease biology. Please join the session that will help you understand more about this important topic. We hope to see you there!

Polish Academy of Science Division of Agricultural and Natural Sciences Award 2025!!! Not everyone could join due to the complicated geography issues (Soham and Juan). I would like to extend my gratitude to all team members, as well as friends from different labs who contributed to our work.

Removal of Transgenes and Evaluation of Yield Penalties in Genome Edited Bacterial Blight Resistant Rice Varieties Bacterial blight (BB) of rice, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the major drivers of yield losses in Africa and Asia. Xoo secretes TAL-effectors (TALe) that induce host SWEET ....

Localized glutamine leakage drives the spatial structure of root microbial colonization Plant roots release exudates to encourage microbiome assembly, which influences the function and stress resilience of plants. How specific exudates drive spatial colonization patterns remains largely ...

Very nice work

Loss of PMR4 callose synthase results in salicylic acid-independent and broad-spectrum resistance to clubroot in Arabidopsis and Brassica napus The clubroot disease caused by protist Plasmodiophora brassicae is one of the most important diseases of Brassica crops. Growing clubroot-resistant cultivars remains the most effective and practical a...

Cool. Good luck with it.

Thanks Deeksha. I am already at home. Time in Ghent was great. Now I am reading papers and thinking about more experiments...

And just like that #ICAR2025 is over! With our prize winners, a special appearance from the legendary Marc Van Montagu & a thank you to our hosts Tom Beeckman & @moritznowack.bsky.social, we can now hand over the baton to Singapore for #ICAR2026! See you all there for more excellent #plantscience!

Speakers of the session Robert Malinowski, Nora Gigli Bisceglia, Timo Engelsdorf, Fariha Naz Apon, Luca Piccinini, Olga Serra And chair Kaisa Kajala

Thank you for the speakers of the cell wall diversity session #ICAR2025, really highlighting the diversity of cell wall roles and approaches!

Also thank you @lauraragni.bsky.social for efficient co-organization!

It was great to be a part of it.

ICAR 2025 Ghent

Excited to see this story out! 🎉 Big congrats to @leoniekraska.bsky.social, @tonnigrubeandersen.bsky.social, and the whole team.
More coming soon on the role of our favorite MYBs in cork suberization—stay tuned!

Warming up to #ICAR2025 🌱with two days of cool vascular science at our Vascular Development satellite meeting at @psb-vib.bsky.social.

Why “basic,” plant science research – esp. in #Arabidopsis - is important and vital to the survival of humanity.

Great achievement of Jiao Zhao, Dongbo Shi, Kiara Kaeufer, and everybody involved!

No idea what did you loose but a good wine is always good.

Nice and impressive work. Congratulations.

Deadline for this position is coming up (2 April). Consider applying if you are interested.

Nice Arabidopsis plant found today...

We will do it for sure.
