title: [Electron microscopic study of thylakoid structure in cyanobacteria].
abstract: Two or three thylakoids can be detected in Synechococcus elongatus, strain 58, and Plectonema boryanum if sections are successful. Peripheral thylakoids sometimes seem to be connected with the cytoplasmic membrane. Partitions and septa, as well as small electron-dense granules typical of cells which underwent lysis, are found in the intrathylakoidal space. Branching of thylakoids is described. Particles 16 and 11 nm in size whose possible nature is discussed can be discerned on the fracture faces. Phycobilisomes have not been discovered by the technique of freeze-etching.
