Using a GFP insertional mutagenesis approach, we generated a partially functional GFP-tagged BAK1 to demonstrate that, following Pep1 elicitation, BAK1 and PEPR1 are endocytosed together with similar dynamics.

Credits to @nvukas.bsky.social !

We dedicate this work to the memory of Philip Benfey, whose visionary contributions, mentorship, and invaluable insights profoundly shaped this research and inspired us personally and scientifically.

This project was led by @nvukas.bsky.social with key contributions from Che-Wei Hsu, and involved a broad collaboration among several research groups, including the Russinova and @trevormnolan.bsky.social labs. Many thanks to all coauthors! @emmanuellebayer.bsky.social @rachelmshahan.bsky.social

🌱💡 Computational modeling and genetic experiments confirm that this asymmetry optimizes root growth, ensuring robust meristem function. @wabniklab.bsky.social

🧩 What's behind this asymmetry? Intrinsic cell polarity! Polar-localized OPS-family proteins sequester ATSK kinases, selectively boosting BR signaling in the upper daughter cell.

📸After division, daughter cells show surprising differences: one rapidly reactivates BR signaling, while the other enhances hormone biosynthesis. This division-of-labor strategy circumvents feedback loops that would normally suppress hormone production.

🧬 Brassinosteroid (BR) signaling dynamically fluctuates across the cell cycle, peaking during the G1 phase and sharply declining during mitosis.

🌱 When a root cell undergoes symmetric division, are the daughter cells actually identical? By combining live-cell imaging and scRNAseq we discovered a new cell state with uneven BR activity. Read our full paper in Cell: doi.org/10.1016/j.ce... @nvukas.bsky.social @trevormnolan.bsky.social

So happy to see this published! @emmanuellebayer.bsky.social and @yvonjaillais.bsky.social labs congratulations👏🌱! Thanks for including us!

This year’s edition of our internal PSB @psb-vib.bsky.social symposium #PSBmeets25 in full swing. Off to 2 days of seminars, poster sessions, discussions, and party!

My first post here. Beautiful morning to start day 3 of the #GRCPlant proteolysis meeting . #Barga, Italy
