Abstract
Molecular biological and spectroscopic techniques will be used to identify gene products involved in mediating the interaction between phycobilisomes and photosynthetic reaction centres in cyanobacteria. The transposon Tn5 will be used to generate a library of random, genetically tagged mutants of the cyanobacterium Synechocystis 6803. Screening of colonies with a fluorescence video imaging system will be used to select mutants that are specifically deficient in: a) energy transfer from phycobilisomes to photosystem l; b) energy transfer from phycobilisomes to photosystem ll; c) a physiological adaptation mechanism which regulates light harvesting. The mutants will be further characterised by spectroscopy and the genes which are the sites of transposon insertion will be identified.
