How energy funnels from the phycoerythrin antenna complex to photosystem I and photosystem II in cryptophyte Rhodomonas CS24 cells

Article Abstract:

Analyses of steady-state and time-resolved fluorescence anisotropy measurements are used to investigate energy migration dynamics in intact cells of the photosynthetic cryptophyte Rhodomonas CS24. Equal distribution of excitation energy is shown from phycoerythrin 545 (PE545) to both photosystem I (PSI) and photosystem (PSII), whose trap times correspond well to those obtained from experiments on isolated photosystems.

Red spectral forms of chlorophylls in green plant PSI- a site selective and high-pressure spectroscopy study

Article Abstract:

Photosystem I (PSI) complexes, possess absorption and emission bands at lower energy than those of the reaction center, is one of its special spectroscopic characteristics. The pigment dimers are responsible for the red states and these red excited states can be interpreted as excimer states.

Light harvesting by chlorophylls and carotenoids in the photosystem I core complex of synechococcus elongatus: A fluorescence upconversion study

Article Abstract:

EA fluorescence upconversion study on trimeric photosystem I particles of the cyanobacterium Synechococcus longatus is presented. Time resolved fluorescence anisotropy measurements, which indicate the time scale of elementary energy transfer steps in the PSI core antenna is described.
