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.

A combined lipidomic and proteomic profiling of Arabidopsis thaliana plasma membrane

This paper provides the first combined lipidomic and proteomic reference of the Arabidopsis thaliana plasma membrane, identifying 2,165 proteins and 405 lipid species.

A global LC-MS2-based methodology to identify and quantify anionic phospholipids in plant samples

This paper develops a sensitive HPLC-MS2 method to quantify anionic phospholipids in plants, revealing PS enrichment in root tissues of Arabidopsis.

Reduced light access promotes hypocotyl growth via autophagy-mediated recycling

This study shows that reduced light and LRFR promote hypocotyl growth through distinct metabolic pathways: autophagy-mediated recycling and plasma membrane lipid biosynthesis.

Impact of membrane lipid polyunsaturation on dopamine D2 receptor ligand binding and signaling

This study shows that n-3 PUFAs enhance D2R ligand binding and signaling, suggesting they act as allosteric modulators of the receptor.

Sphingolipids are involved in Pieris brassicae egg-induced cell death in Arabidopsis thaliana

This study shows that sphingolipids, specifically ceramides with C16:0 side-chains, are downstream activators of HR-like cell death in Arabidopsis triggered by Pieris brassicae eggs, independent of SA signaling.

Purification, characterization and influence on membrane properties of the plant-specific sphingolipids GIPC

This study characterizes plant-specific GIPC sphingolipids, showing they increase membrane thickness, electronegativity, and regulate phase transitions.

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.
