The kinetic component (39 ps) for the energy transfer from a phycobilisome (PBS) to the photosystems was temperature-dependent while the components related to the kinetic processes within PBS, photosystem 2 (PS2) or PSI were temperature-independent. The 39 ps component possessed the amplitude maximum at 647 nm but the minimum at 715 nm (room temperature) or 685 nm (0 degreeC), suggesting a direct energy transfer from C-phycocyanin to PSI at room temperature but to PS2 at 0 degreeC. The temperature-induced kinetic change originated from a position shift of PBS along the thylakoid membrane.
