  • Title: Flow cytofluorometric analysis of the nuclear division cycle of Physarum polycephalum plasmodia.
    Author: Murphy RF, Daban JR, Cantor CR.
    Journal: Cytometry; 1981 Jul; 2(1):26-30. PubMed ID: 7273974.
    Abstract:
    The nuclear cycle kinetics of Physarum polycephalum plasmodia were examined using flow cytofluorometry. The dyes Hoechst 33342 and propidium iodide were used to stain the DNA of isolated nuclei. In asynchronously growing microplasmodia. S phase consists of 13--15% of the nuclear division cycle time. Nuclei isolated from individual macroplasmodia, which have previously been demonstrated to divide in synchrony, were shown to be less synchronized during late S phase than during mitosis. The results obtained demonstrate the feasibility of flow cytometric measurement of the properties of nuclei isolated from a single cell.
