In the cyanobacterium Synechocystis 6714 we show that changes in light energy distribution are controlled by the redox state of the PQ pool and we report on the deep ultrastructural modifications caused by these changes. We conclude that State I‐State II transitions correspond to an increased energy transfer between PS II and PS I through a randomization of the EF particles of the thylakoid membranes. This reorganization could involve a change in the interaction between PS II centers and the phycobilisomes.
