The sweet and sour of sugar uptake in plants – a structural take
PhD defense, Friday 3 February 2023, Laust Bavnhøj
During his PhD studies, Laust Bavnhøj investigated sugar transport proteins involved in sugar uptake across plant cell membranes. Sugar transport is indispensable for the growth and development of plants as well as their responses to environmental cues.
Laust Bavnhøj explored structural determination and biochemical characterization of sugar transporters from two central sugar transporters families, the Sugar Transport Protein (STP) family and the Sucrose Carrier (SUC) family that are unique to plants. The studies provide structural insights into the molecular basis of proton-driven sugar transport mechanisms of proteins from both families, which combined with biochemical investigations reveal structural elements that are pivotal for transport function. Unearthing these fundamental processes opens new routes for addressing future challenges related to a global food security and a rapidly changing environment.
The PhD study was completed at the Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University.
