Nanoscale regulation of ROS signaling at the plasma membrane tunes the plant response to osmotic stress

Arthur Poitout, José Manuel Ugalde, Lucille Gorgues…·Alexandre Martinière

This study shows that localized H2O2 nanodomains at the plasma membrane regulate ROP6 clustering and plant response to osmotic stress.

Sphingolipid-driven interleaflet coupling orchestrates Rho-GTPase recruitment to nanodomains for signal activation in plants

Matheus Montrazi, Arthur Poitout, Camille Depenveiller…·Yohann Boutté

The paper shows sphingolipid-driven interleaflet coupling organizes nanodomains and activates Rho-GTPase in plants, linking membrane asymmetry to signaling.
