Such a pleasure to meet and discuss with ancient colleagues and friends from RDP- Lyon and IPSIM-Montpellier. Plant membrane meeting June 2025. Thanks for the organization @alexmartiniere.bsky.social🙌🏼 @lbm-bordeaux.bsky.social @rdplab.bsky.social

2/ Phosphoinositides (PIPs) are key lipids that define membrane identity. We visualised PI(4,5)P₂ and PI4P biosensors from @yvonjaillais.bsky.social in Nicotiana benthamiana during root colonisation by a mutualist AM fungus - F. mosseae and a pathogen - P. palmivora. www.biorxiv.org/content/10.1...

1/🚨 New preprint alert! Can mutualists and pathogens co-colonise the same living plant cell and what does that do to the plant membranes that surround these microbes?

A big thanks to all the speakers of the session on cell-to-cell communication #ICAR2025👏👏👏 @pdchristine.bsky.social @pmarhavy.bsky.social @matiasgleason.bsky.social @rebeccaburkart.bsky.social Dimitra Valadourou 🙏Many thanks to my co-chairs @yvonjaillais.bsky.social and Isabelle Fobis-Loisy

🚨Our paper is out! If you ever wonder how four-way junctions are avoided during plant cell division, some answers here 🧬🍀🔬🧪🤓 👇 www.sciencedirect.com/science/arti...

Plant Science Research Weekly -- Plasmodesmata: a new frontier for membrane contact site intercellular communication (Cell) @emmanuellebayer.bsky.social @yvonjaillais.bsky.social (Summary by Stephanie Temnyk) buff.ly/aSoKPZ1 #PlantaePSRW

We're looking for a postdoc to join the lab to work on cell-to-cell communication via the apoplast. Candidate must be brave, as they will have to lead us (me) away from the plasmodesmata-lands we've inhabited for so long! www.jic.ac.uk/vacancies/po...

🌱 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

Exited to announce our study on ER-Golgi Intermediate Compartment (ERGIC) in plants!! www.nature.com/articles/s41... Amazing and innovative work from @louisefougere.bsky.social and Magali Grison from @lbm-bordeaux.bsky.social, #SuperResolution, @naturecellbiology.bsky.social

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

Great collaboration with @yvonjaillais.bsky.social 🌱 Plants use membrane contact sites (MCS) for cell-to-cell signaling! ➡️ MCTP tethers & PI4P regulate ER-PM contacts in plasmodesmata, impacting trafficking. ➡️ MCS roles span intra- and intercellular communication. www.cell.com/cell/abstrac...

Next speaker for our @iecb.bsky.social Friday seminar (06.12.2024) is @yvonjaillais.bsky.social form @rdplab.bsky.social Lyon. Open to the whole scientific community of Bordeaux! Organised by @habenstein.bsky.social .

With Marie Cecile Caillaud and Isabelle Fobis-Loisy, we are organizing a concurrent session at ICAR next year #ICAR2025 (Gent, Belgium June 16-20 2025). - How do cells talk to each other? New frontiers in cell-to-cell communication web.cvent.com/event/448810...

There is still some time left to register if you want to follow the Cell Biology of Plants and Beyond symposium online. It's on Friday and the program is 🔥. Don't miss it! You just have to register here before Jan 23: sbcf.fr/en/event/the...

Ok, #Plasmodesmata and #PlantScience Fans, if you're too lazy to read the two #preprints from Emmanuelle M. Bayer, @yvonjaillais.bsky.social, et al. in their entireties (see quoted post below), you can now go straight to this #preLights summary by @gwenkirschner.bsky.social:

Thank you, Marc for posting! I am really excited about these findings. Cell-to-cell diffusion via plasmodesmata is not only regulated by callose but also by regulating ER/PM membrane spacing. This is achieved by the concerted action of tethering proteins in the ER and a plasma membrane lipid, PI4P.
