Communication and Dynamics of Plant Cell Compartments

13 Apr// Till Ischebeck as speaker at the HPSC

On Tuesday, 13 April Dr. Till Ischbeck from Georg-August-University Göttingen, Albrecht-von-Haller-Institute for Plant Sciences is going to give an online talk as part of the Halle Plant Science Colloquium HPSC at 5:00 pm. The research of his group focuses on four partly interconnected topics: plant lipid droplets, pollen development and pollen tube growth, analytics of small metabolites, and plant-pathogen interactions. We’re looking forward to hear his presentation titled “Identification of a lipid droplet-plasma membrane tethering complex in Arabidopsis”, which will provide new insights into his research.

Abstract: Lipid droplets (LDs, also referred to as oleosomes or oil bodies) are unique subcellular compartments consisting of a phospholipidmonolayer surrounding a hydrophobic core of predominantly triacylglycerol and sterol esters. We are using proteomics and microscopy to identify proteins associated with LDs and to study their function. This way we aim to learn more about the subcellular and physiological functions of LDs. One aspect that we are especially interested in are how LDs interact with other subcellular structures to fulfil their function. One mode of interaction are membrane contact sites (MCS) that allow for the direct exchange of molecules, such as lipids between compartments, but can also serve to tether compartments at specific locations in cells. We found such a MCS between LDs and the plasma membrane and identified three proteins important for its constitution.
