Epifluorescence microscopy ofAnabaena sp.: Nucleoid configurations and evidence for inclusion-associated DNA

Abstract

Vital staining of the nucleoid inAnabaena sp. PCC7118 was performed using the double stranded DNA-specific fluorochrome DAPI. In the unicellular mutant, the central epifluorescent zone had a dense skein configuration, while in the filamentous parent strain protrusions, lobes, and distinct isolated elements of the nucleoid were visible. Both variants… (More)
