Abstract

This project will investigate the role of the minor light harvesting complexes (LHCIIa and LHCIIc) in the regulation of light harvesting in photosystem II in higher plants, in particular their involvement in the dissipation of excess excitation energy that provides protection from photodamage. The protein domains responsible for sensing the thylakoid H+ gradient will be determined and the changes in pigment/pigment and pigment/protein and protein/protein interactions resulting from protonation will be explored using spectroscopic methods in order to elucidate the mechanism of quenching. The approach will be to use specified pigment protein complexes, wild type and mutant complexes reconstituted from pigments and protein synthesised in E. coli, thylakoid membranes and leaves so that in vitro behaviour can be related to in vivo function.
