title: A particular structure associated to the nucleoid of cyanobacteria.
abstract: Regressive staining as well as beta-radiations or trypsin treatment on Synechocystis PCC6803 and Spirulina platensis (Gom,-Geilteri.) whole cells or permeaplasts, respectively, have demonstrated the presence of a particular structure associated to the nucleoid of cyanobacteria. This structure with a tridimensional network aspect has been called scaffold-like. We presume that it represents the cellular-molecular support for the supercoiling of the nucleoid of cyanobacteria.
