Abstract

The light harvesting system of plants is characterised by a biochemical complexity and a dynamical function which enables it to rapidly and reversibly switch from a state of efficient light harvesting to a state in which absorbed energy is dissipated as heat. The aim of this project is to elucidate at the pigment and protein level the molecular basis of this important and complex regulatory mechanism. By using various spectroscopies and electron microscopy applied to purified light harvesting complexes (LHCII), macromolecular LHCII supercomplexes and intact chloroplast membranes, the physical mechanism of energy dissipation, the causitive structural changes in LHCII, and the role of carotenoids and protonation as regulatory modulators will be determined.
