Abstract

This article summarizes our ultrastructural studies on the organization of the thylakoid membrane of green algae and higher plants. We have used freeze-fracture and immunogold labeling to investigate the lateral distribution of the components in the membrane, their interactions, and the folding of their polypeptide chains in the membrane.
