DNA-Specific DAPI Staining of the Pyrenoid Matrix During its Fission in Dunaliella salina (Dunal) Teodoresco (Chlorophyta).

The algal pyrenoid is a naked phase-separated liquid compartment inside the chloroplast consisting predominantly of densely packaged Rubisco and most often transversed by a system of lipid membranes. The pyrenoid participates in carbon-concentrating mechanisms of algae. During the cell division, the daughter cells of algae acquire the pyrenoids via their assembly or fission, the mechanisms of which are not fully understood.
