title: Cooperation of cytoplasmic and plastidial translation in formation of the photosynthetic apparatus and its stage-specific efficiency.
abstract: In synchronized Euglena gracilis, strain Z, the synthesis of the apoproteins for the chlorophyll-protein-complexes CPI, CPa, and LHCP is light-dependent and takes place in the light period in a characteristic consecutive fashion: CPI at 1 to 2 hours, CPa at 7 to 12 hours, and LHCP at 8 to 12 hours. The syntheses sequence of the chlorophyll-protein-complexes coincides with the efficiency alterations of the photosynthetic apparatus of E. gracilis during the light period of the cell cycle. In particular, the synthesis onset of the photosystem II-related polypeptides CPa and LHCP aligns with the decrease of oxygen evolution at 6 hours of the light period and is discussed as reorganization process in the thylakoids.
