Resumé

In the present study, we determined characteristic repeat distances of the photosynthetic membranes in living cyanobacterial and eukaryotic algal cells, and in intact thylakoid membranes isolated from higher plants with time-resolved small-angle neutron scattering. This non-invasive technique reveals lightinduced reversible reorganizations in the seconds-to-minutes time scale, which appear to be associated with functional changes in vivo.
