LIPID DROPLET PROTEIN OF SEEDS is involved in the control of lipid droplet size in Arabidopsis seeds and seedlings Open
In oilseeds, energy-rich carbon is stored as triacylglycerols in organelles called lipid droplets (LDs). While several of the major biogenetic proteins involved in LD formation have been identified, the full repertoire of LD proteins and t…

Identification of <span>INOSITOL PHOSPHORYLCERAMIDE SYNTHASE</span> 2 ( <span>IPCS2</span> ) as a new rate‐limiting component in Arabidopsis pathogen entry control Open
SUMMARY INOSITOL PHOSPHORYLCERAMIDE SYNTHASE 2 (IPCS2) is involved in the biosynthesis of complex sphingolipids at the trans ‐Golgi network (TGN). Here, we demonstrate a role of IPCS2 in penetration resistance against non‐adapted powdery m…

Inhibition of Very Long Chain Fatty Acids Synthesis Mediates PI3P Homeostasis at Endosomal Compartments Open
A main characteristic of sphingolipids is the presence of a very long chain fatty acid (VLCFA) whose function in cellular processes is not yet fully understood. VLCFAs of sphingolipids are involved in the intracellular traffic to the vacuo…

LDIP cooperates with SEIPIN and LDAP to facilitate lipid droplet biogenesis in Arabidopsis Open
Cytoplasmic lipid droplets (LDs) are evolutionarily conserved organelles that store neutral lipids and play critical roles in plant growth, development, and stress responses. However, the molecular mechanisms underlying their biogenesis at…

SEIPIN Isoforms Interact with the Membrane-Tethering Protein VAP27-1 for Lipid Droplet Formation Open
SEIPIN proteins are localized to endoplasmic reticulum (ER)-lipid droplet (LD) junctions where they mediate the directional formation of LDs into the cytoplasm in eukaryotic cells. Unlike in animal and yeast cells, which have single SEIPIN…

Lipid Droplet–Peroxisome Connections in Plants Open
Lipid droplets (LDs) are the principal subcellular sites for the storage of triacylglycerols (TAGs), and in plants, TAG degradation requires metabolism in peroxisomes. This metabolic cooperation includes TAG hydrolysis by the sugar-depende…

Rho-of-plant activated root hair formation requires <i>Arabidopsis YIP4a/b</i> gene function Open
Root hairs are protrusions from root epidermal cells with crucial roles in plant soil interactions. Although much is known about patterning, polarity and tip growth of root hairs, contributions of membrane trafficking to hair initiation re…

La protéomique de sous-domaines du trans-Golgi Network révèle un lien entre les sphingolipides et les phosphoinositides chez la plante. Open
La polarité cellulaire est une caractéristique commune à tous les organismes. Jusqu’à récemment, il était assumé que la sécrétion de protéines vers des domaines polaires de la cellule végétale se faisait de façon non polarisée, mais ce poi…

Proteomic Analysis of Lipid Droplets from Arabidopsis Aging Leaves Brings New Insight into Their Biogenesis and Functions Open
Lipid droplets (LDs) are cell compartments specialized for oil storage. Although their role and biogenesis are relatively well documented in seeds, little is known about their composition, structure and function in senescing leaves where t…
