Reversible uncoupling of energy transfer between phycobilins and chlorophyll in Anacystis nidulans: light stimulation of cold-induced phycobilisome detachment.

Phycobilin fluorescence of Anacystis nidulans grown at 28 degrees C increases substantially upon cooling below 10 degrees C. A maximal increase is found around -5 degrees C and amounts to 300%, with almost complete reversibility upon re-warming. Illumination with actinic light leads to considerable stimulation of the cold-induced phycobilin fluorescence… CONTINUE READING
