A flow cytometry study of the cell cycle and of ploidy levels in Physarum polycephalum myxamoebae and plasmodia.

The cell cycle of Physarum polycephalum myxamoebae, as well as haploid and diploid and plasmodia, was analysed using laser microfluorometry. The data obtained indicate that the cell cycle of all strains examined are similar. The DNA profiles also indicate that a haploid ploidy level is still uncertain and show conclusively that spontaneous chromosome loss is a parameter of concern in research involving these organisms.
