We are very excited to share a new resource from our team: spatial subcellular proteome maps in plants! We developed an MS-based method that registers localizations of about 8000 proteins in Arabidopsis roots in a single experiment.

Thank you, Arif! Hope we can catch up in a meeting anytime soon!

Thank you, Juan! Congratulations on your new position, too! 😄

Thank you, Nathan!

A new chapter begins! From February, I’ll be joining the @tum.de as an Independent Group Leader in the Chair of Plant Systems Biology. Beyond excited for this next step, while feeling very grateful (and a little sad) to be leaving the @schaedellab.bsky.social 🔬🌱

Hey #plantsci, have your experiments led to a negative result? These important findings are worth publishing to push scientific knowledge forward! @plosone.org is focussed on scientific rigour rather than impact, and selfishly I would LOVE to see more #plantscience each day :D #PhDchat #ECRchat 🌿🧪🔬💚

Transcriptional control of meiotic recombination by the DREAM complex Meiotic chromosome segregation and recombination, essential for sexual reproduction and evolution, require a specialized gene set. However, how meiotic gene expression is controlled remains largely un...

BUT: restoring MER3 can partly rescue fertility. With DREAM’s role conserved from plants to animals, we’re excited to shed light on how reproduction is orchestrated across multicellular life! 🌱🔬✨ #Meiosis #Science #PlantBiology

Excited to share this preprint on the microtubule severing protein Katanin, and its role in cell elongation and division in maize. First author Stephanie Martinez worked collaboratively with many folks to bring you this preprint. Check it out! 🔬🌽 www.biorxiv.org/content/10.1...

Have you ever wondered how microtubules withstand and respond to mechanical stress in cells?

Here we show by in vitro reconstitution assays that MAP65-1 and PRC1 promote microtubule nucleation on existing lattices, especially on those with structural irregularities linked to mechanical stress.

Despite their high rigidity, microtubules (MTs) dynamically bend and buckle in cells. MT-self repair is inherent to their metastable nature, but it remains unclear whether just inherent repair mechanisms are sufficient to maintain MT integrity🧵 (1/9)

Happy to share that our paper on Tau- Microtubule interaction is now published in Nature Physics!🥳

We show that Tau isn’t just a microtubule stabiliser - it promotes removal of defects in the microtubule lattice.

Congratulations @subhambiswas.bsky.social!

🌱✂️ How do plant cells decide where to divide?

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.
