AB The lipidome remodeling during cold acclimation is an important evolutionarymilestone to plant adaption to sub-optimal temperature conditions. In Arabidopsis, thephospholipid binding protein Synaptotagmin1 (SYT1) maintains the plasma membrane(PM) integrity during abiotic stress (1, 2) , participates in the Ca2+-dependent acquisition offreezing tolerance (3), and it is involved in viral protein cell-to-cell movement (4). Despitethese important roles, its PM delivery mechanisms, lipid membrane targets, and in vivoeffects on lipid composition have been largely overlooked. In this report (5), we establishthat SYT1 is an ER and PM associated protein that specifically binds negatively chargedphosphoinositides and glycerolipids, and its loss causes the over-accumulation of itsphospholipid binding partners in vivo. We also present a preliminary characterization ofSYT3, an additional phospholipid binding member of the Arabidopsis SYT family, as aunique stress inducible determinant required for lipidome remodeling during cold stressepisodes.
