title: Ultrastructure - function relationship in Chlamydomonas reinhartii thylakoids, by means of a comparison between the wild type and the F34 mutant which lacks the photosystem II reaction center.
abstract: The F34 mutant strain of Chlamydomonas reinhartii is deficient in photosystem II reaction centers. The E fracture faces of the thylakoid membranes of this mutant show a considerable reduction in the number of particles present ant in their size compared with the wild type. We conclude that the polypeptides associated with photosystem II reaction centers, which are missing in SDS polyacrylamide gel electrophoresis patterns of proteins from this mutant strain, are part of the EF particles and are required for assembly of these particles.
