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...

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.

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.
