CONTROL OF QUANTAL DISTRIBUTION TO THE TWO PHOTOSYSTEMS
The object of research programme Contract No. 016-76 ESUK was to gain a better understanding of the organization of the photosynthetic pigments in 0-2 evolving organisms and elucidate the mechanisms controlling energy transfer to the two photosystems. In our work we have concerned ourselves with several aspects of in-vivo pigment organization and in particular have focused on the importance of the membrane system involved. We have investigated the electrical, and associated ionic properties of the thylakoid membrane with a view to understanding the regulatory interactions which occur between the various pigment - protein complexes. Our approach has been to study steady state chlorophyll fluorescence yield changes and to monitor picosecond time resolved fluorescence decays under a number of different conditions. Because our work has emphasised the importance of membrane surface charges in the control mechanism of energy transfer between the chlorophylls of PS1 and PS2, we have conducted detailed particle electrophoresis and neutron activation studies and studies involving the use of charged fluorescence probes.
