Interdependence of plasma membrane nanoscale dynamics of a kinase and its cognate substrate underlies Arabidopsis response to viral infection

This study shows that CPK3 and its substrate REM1.2 interact dynamically at the plasma membrane, influencing viral propagation in Arabidopsis.

Mechanosensing and Sphingolipid-Docking Mediate Lipopetide-Induced Immunity in Arabidopsis

This study identifies that lipopeptide elicitor surfactin activates immunity in Arabidopsis by docking into sphingolipid domains, causing membrane deformation and mechanosensitive ion channel activation, leading to resistance against B. cinerea.

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.

The actin depolymerizing factor StADF2 alters StREM1.3 plasma membrane nanodomains to inhibit the Potato Virus X

This study shows that StADF2 alters StREM1.3 plasma membrane nanodomains to inhibit PVX cell-to-cell movement through REMORIN-dependent mechanisms.

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.

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.

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.

A hetero-oligomeric remorin-receptor complex regulates plant development

The paper shows that Group 1 remorins form a hetero-oligomeric complex at the plasma membrane, recruiting RIR1 and NILR2 to regulate plant development.

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.

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.
