- Abstract:
- Fluorescence lifetime measurements with picosecond resolution will be used to probe the deactivation kinetics of excitons in the light harvesting antenna of photosystem II in intact phytoplankton cells. Comparison between the direct excitation of chlorophyll a and indirect excitation via carotenoids, will make it possible to isolate decay components corresponding to the development of carotenoid-mediated photoprotection. Results will be compared with those obtained from HPLC Determinations of carotenoid types in cells grown under different light regimes. The project will lead to a purely optical method of determining the efficiency with which energy derived from absorbed photons are conveyed to the PSII reaction centre, a key factor in formulating models of primary production.
