| Abstract |
We examined energy transfer dynamics from the photosystem II reaction center (PSII-RC) in intact red algae cells of Porphyridium cruentum, Bangia fuscopurpurea, Porphyra yezoensis, Chondrus giganteus, and Prionitis crispata. Time resolved fluorescence measurements were conducted in the range of 0-80ns at -196°C. The delayed fluorescence spectra were then determined, where the delayed fluorescence was derived from the charge recombination between P680(+) and pheophytin a in PSII-RC. Therefore, the delayed fluorescence spectrum reflected the energy migration processes including PSII-RC. All samples examined showed prominent distribution of delayed fluorescence in PSII and PSI, which suggests that a certain amount of PSII attaches to PSI to share excitation energy in red algae. The energy transfer from PSII to PSI was found to be dominant when the amount of phycoerythrobilin was increased. |
