TLDR
The phenomena of intensity adaptation and complementary chromatic adaptation yield insights into the structure of phycobilisomes and the molecular basis of the plasticity of the structure in this light-harvesting system.Abstract:
Cyanobacteria (blue-green algae) and Rhodophyta (red algae) contain high concentrations of photosynthetic accessory pigments (phycobiliproteins) which trap light energy in the region between 400 and 650 nm. The electronic excitation energy is then transferred along a chain of these pigments to the reaction center chlorophyll of Photosystem II by a radiationless induced resonance process.read more

TL;DR: In the present study, the hemi-discoidal phycobilisomes of several species of cyanobacteria were examined in thin sections of cells and by negative staining after isolation and fixation and it was suggested that the triangular core was composed of allophycocyanin and that the peripheral rods contained phyCocyan in and phycoerythrin (when present).

Detection of single molecules of phycoerythrin in hydrodynamically focused flows by laser-induced fluorescence.
TL;DR: Single molecules of B-phycoerythrin were detected by laser-induced fluorescence in hydrodynamically focused flows as each molecule transited a focused laser beam.

Phycoerythrocyanin and Phycoerythrin: Properties and Occurrence in Cyanobacteria
TL;DR: The synthesis of phycoerythrocyanin was not controlled by a complementary chromatic adaptation mechanism in nine strains tested, but its synthesis appeared to be affected by light intensity.

Structure and Function of Phycobilisomes: Light Harvesting Pigment Complexes in Red and Blue-Green Algae
TL;DR: This chapter focuses on the phycobilisome characteristics, their relationship to the photosystems in the thylakoid membrane, and major problems to be addressed in future investigations.
