Les phosphoinositides sont des lipides membranaires anioniques peu abondants .Leurs concentrations relatives dans les feuillets cytosoliques de la membrane plasmique et de certaines membranes internes des cellules eucaryotes constituent des signatures moléculaires. Le phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2 ] en particulier a pour l’instant seulement été détecté à la membrane plasmique dans les cellules de levure, animales ou végétales.Nous avons utilisé l’organisme modèle Arabidopsis thaliana (Arabette des dames) pour étudier le PI(4,5)P2. Dans un mutant perte de fonction où l’équilibre entre PI(4,5)P2 et phosphatidylinositol-4-phosphate (PI4P) est modifié, nous avons observé la présence anormale de PI(4,5)P2 dans des compartiment...
