Picosecond time-gated fluorescence imaging of Photosystem II particles and spinach leaves

摘要

Picosecond fluorescence of plant photosynthetic proteins has been widely used to study energy and electron transfer in isolated particles of Photosystem II (PS II), Light-Harvesting Complexes and other related systems. The distribution of fluorescence emitted from whole plant material has been imaged previously but so far this has involved measurement of the time-averaged fluorescence with little attention to the spatial variation of picosecond fluorescence components in the tissue.
