Chitosan stimulates root hair callose deposition and inhibits root hair growth

This study shows chitosan induces callose deposition and slows root hair growth in Arabidopsis, with distinct responses at low and high concentrations, and identifies conserved mechanisms in related plant structures.

Biomolecular condensation orchestrates clathrin-mediated endocytosis in plants

This study shows that AtEH1 and AtEH2 subunits of the TPC complex drive biomolecular condensation to facilitate clathrin-mediated endocytosis in plants, with their disordered regions regulating condensate properties and endocytosis dynamics.

The TPLATE subunit is essential for structural assembly of the endocytic TSET complex

The paper determines the structural architecture of the plant TSET complex and identifies key interactions essential for its assembly and function in endocytosis.

Distinct EH domains of the endocytic TPLATE complex confer lipid and protein binding.

This study identifies distinct lipid and protein binding roles of EH domains in the TPLATE complex, revealing their functional contributions to plant clathrin-mediated endocytosis.

EXO70A2 is critical for the exocyst complex function in Arabidopsis pollen

This study identifies EXO70A2 as essential for exocyst complex function in Arabidopsis pollen, critical for pollen development, germination, and tube growth.

Functional analysis of phospholipase Dδ family in tobacco pollen tubes

This study identifies PLDδ3 as the key isoform responsible for PA production in tobacco pollen tubes and shows its role in PM invagination and membrane trafficking.

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.
