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.

The abstract deadline is extended until the end of the week, don't hesitate to register, it's free and it will be a great symposium touching many aspects of Plant Cell Biology.

Great lineup of speakers: Marie Barberon, Amélie Bernard, Franziska Lautenschläger, Sophie Martin, Moritz Nowack, Thomas Ott, René Schneider, Joris Sprakel. 8 talks will be selected on abstracts, as well as a poster session. We are looking forward to welcoming you in Lyon!
