ATG8ylation of vacuolar membrane protects plants against cell wall damage

This study identifies a vacuolar quality control pathway in plants that uses ATG8ylation to protect vacuolar integrity following cell wall damage.

Peripheral membrane proteins modulate stress tolerance by safeguarding cellulose synthases

The paper identifies TTL proteins as essential for maintaining cellulose synthesis under stress by stabilizing the cellulose synthase complex and cortical microtubules.

The Arabidopsis SAC9 Enzyme is enriched in a cortical population of early endosomes and restricts PI(4,5)P2 at the Plasma Membrane

The paper shows SAC9 restricts PI(4,5)P2 at the plasma membrane, preventing its ectopic accumulation in intracellular compartments and affecting clathrin-mediated endocytosis and SH3P2 localization.

A nanodomain anchored-scaffolding complex is required for PI4Kα function and localization in plants

The paper identifies a nanodomain-anchored scaffolding complex essential for PI4K1 localization and function in plants, revealing its role in membrane lipid dynamics and development.

In vivo phosphatidylserine variations steer Rho GTPase signaling in a cell-context dependent manner

The paper shows phosphatidylserine regulates Rho GTPase signaling in Arabidopsis by modulating ROP6 nanoclusters and auxin signaling during root development.

A combinatorial lipid code shapes the electrostatic landscape of plant endomembranes

The paper identifies specific lipids that control membrane electrostatics in plant cells and shows how their combination creates distinct electrostatic territories along the endocytic pathway.
