- Huge shoutout to the #PMS2025 live tweeters @evolvedbiofilm.bsky.social, @courtneyherms.bsky.social, and @gstringlis.bsky.social for their amazing coverage! Thanks for keeping the excitement alive and the community connected throughout the symposium 👏
- What a nice surprise to receive a small appreciation (🇪🇸jamón&cheese 😋) for our social media activities at #PMS2025 together with @courtneyherms.bsky.social and @gstringlis.bsky.social
- Huge thanks to the #PMS2025 organizers for an amazing symposium — inspiring talks, great activities, and an incredible community. Honored to receive the best talk award. Thank you to the judges for this recognition! 🙏😊
- Talk and Poster prizes at #PMS2025 Well done all presenters!!! 👏 including @courtneyherms.bsky.social @hueihsuantsai.bsky.social and @dgarrs.bsky.social

- Totally agree, it's such a fascinating and beautiful story!!
- Thank you 😊
- Thank you Courtney 😊😊😊
- Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science! (1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.
- Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other. Learn more in this week's issue: scim.ag/3WgNajk

- NEW ARTICLE FROM THE LAB 🎉🍀🧫 Groundbreaking work performed by @hueihsuantsai.bsky.social and all! Please, go have a read! Congrats to making it to the cover!!! www.science.org/doi/10.1126/...
- Thank you Charles! 😀
- (5/5) Very happy to share this journey with amazing collaborators! Huge thanks to our close collaborators Feng Zhou and Yuanjie Tang! Thank you Valérie D. T., Jia P., @kathywippel.bsky.social, Jordan V., Christoph K., @tonnigrubeandersen.bsky.social & many others for making this possible!
- Read the paper 👉 Localized glutamine leakage drives the spatial structure of root microbial colonization | Science www.science.org/doi/10.1126/...
- (3/5) Bacterial mutants unable to sense amino acids failed to locate these hotspots. To probe further, we generated a glutamine-inducible bacterial reporter strain, enabling high-resolution mapping of bacterial metabolic states along the root.
- (4/5) These findings highlight the fine-scale heterogeneity of nutrient availability along roots and its role in structuring microbial communities.
- (2/5) We show that microbial colonization follows spatial patterns linked to the integrity of the Casparian strip. When the strip is absent or broken—at elongation zones or lateral root emergence sites—glutamine leaks out, attracting microbes and creating colonization hotspots.
- My poster is up and ready at #2025ISMPMI! Curious why bacteria show spatial colonization preferences on roots? If you want to know more, come visit my poster P-248, on Thursday, 13:30–15:15

- Totally, that would be a very interesting application! It's definitely worth exploring! 😁

- Indeed, could be interesting to test! I am not sure if we have the MYB36loop line in our lab already. Let me check! 😃

- Thank you Courtney! The amount of glutamine we detected (leaked from the sgn3myb36 mutant) and applied was in the µM range, and the treatment lasted only 6 hours. Under these conditions, we did not observe any impact of glutamine on plant growth/root development.
- I will be there 😉
- See you there 😊
