Plasmodesmata act as unconventional membrane contact sites regulating inter-cellular molecular exchange in plants

The paper shows plasmodesmata function as ER-PM tubular membrane contact sites that regulate intercellular molecular exchange in plants through PI4P and MCTP proteins.

Invasion of the stigma by the pollen tube or an oomycete pathogen: striking similarities and differences

This study compares how stigma papillae respond to invasion by a pollen tube and an oomycete pathogen, revealing shared and distinct cellular responses.

Driving forces behind remorin nanodomain formation in anionic lipid membranes

The paper investigates how phosphorylation of the N-terminal IDD in REM1.3 influences remorin clustering into lipid nanodomains in anionic model membranes.

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.

Endosperm turgor pressure both promotes and restricts seed growth and size

The paper investigates how endosperm turgor pressure influences seed growth by both promoting expansion and restricting it through mechanical interactions with the seed coat.

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.

A plasma membrane nanoplatform ensures signal specificity during osmotic signaling in plants

The paper shows that Rho GTPase nanodomains at the plasma membrane ensure signal specificity during osmotic signaling in plants by transducing reactive oxygen species production.

Live-cell imaging of early events following pollen perception in self-incompatible Arabidopsis thaliana

The paper uses live-cell imaging in self-incompatible Arabidopsis to show that stigmatic cells control pollen hydration and respond to pollen tube intrusion by remodeling actin cytoskeleton.

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.
