Nuclear matrix proteins of Physarum polycephalum
Molecular Biology Reports, 1986The proteins of nuclear matrix preparations from Physarum polycephalum were compared with analogous mammalian fractions by gel electrophoresis, DNA-binding studies and immunological tests. Polypeptides of 28 and 36 K dalton, which dominate in Physarum preparations, differed from calf thymus matrix proteins in that they were basic and showed low ...

DNA replication in Physarum polycephalum
Journal of Molecular Biology, 1972Abstract The DNA of Physarum polycephalum, a eukaryote whose nuclei divide synchronously, was uniformly-labeled with [14C]thymidine or pulse-labeled for 10 minutes with [3H]thymidine. Nuclei isolated from combined 14C- and 3H-labeled cultures were gently lysed on top of neutral and alkaline sucrose density gradients.

Free Ribonucleotides of Physarum polycephalum
European Journal of Biochemistry, 1969Free ribonucleotides in plasmodia of Physarum polycephalum at different stages of the synchronous mitotic cycle were determined by anion exchange chromatography. The nucleotide pattern of this myxomycete resembled that obtained from rat liver. The contents of total adenine nucleotides based on protein content were almost identical in both tissues ...

Mutagenesis and mutant selection in Physarum polycephalum
Molecular and General Genetics MGG, 1972Physarum polycephalum myxamoebae were exposed to ultraviolet irradiation and plated in the absence and presence of caffeine. Caffeine reduces the shoulder on the UV1 dose-survival curve, thereby increasing the UV-sensitivity for survival. Caffeine alone is a moderate mutagen. Used in conjunction with UV a strong mutagenic action is observed.

Kinetics of Mating inPhysarum Polycephalum
Mycologia, 1979Plasmodium formation by mating was studied in cultures containing equal numbers of mating-compatible amoebae. A period of amoebal multiplication always preceded plasmodium formation. When the inoculum varied from a total of 3 X 103 to 1.6 X 10° cells per culture, plasmodium formation commenced when the total number of cells reached about 5 X 105 per ...

Stage-specific antigens of Physarum polycephalum
Experimental Cell Research, 1980Abstract Antisera were prepared in isogenic F 1 hybrid rats against three amoebal strains and against two genetically related plasmodial strains of Physarum polycephalum . Differences in specificities between the antisera were studied using immunofluorescence tests and Ouchterlony double diffusion tests.

Plasmodial ultrastructure of the myxomycete Physarum polycephalum
Tissue and Cell, 1972Abstract When plasmodia of P. polyeephalutu are fixed simultaneously with osmium tetroxide and glutaraldchyde, the cytoplasm is so preserved that a system of microchannels, resembling pinocytosis channels, and numerous discrete vacuoles can be observed.

Structure of ribosomal DNA in Physarum polycephalum
Journal of Molecular Biology, 1976Abstract The sequences coding for Physarum ribosomal RNA are localized on idependently replicating, linear DNA molecules of a discrete size, M r = 37 × 10 6 . Restriction endonucleases Eco RI and Hin dIII each cut ribosomal DNA into one large and two small fragments.
