Abstract

The life cycle of the myxomycete Physarum flavicomum starts with the germination of spores. The germinating spores produce haploid myxamoebae which multiply by cytokinesis. After syngamy, cytokinesis no longer occurs but karyokinesis does and subsequent growth results in the formation of a diploid syncytial plasmodium. During growth a plasmodium secretes slime which was purified and found to be composed of polysaccharide and protein with a molecular weight of 833,000 daltons, a sedimentation coefficient of 12S, and a pI of about 4.0. Haploid cells, which do not produce slime, were inhibited by the addition of plasmodial slime to the growth medium. [...]
