Glycogen inPhysarum polycephalum

Experientia, 1969
Verschiedene biochemische und elektronenoptische Techniken wurden dazu benutzt, eine partikulare Speicherform fur Glukose inPhysarum polycephalum zu identifizieren. Die Ergebnisse zeigen, dass es sich um Glykogen handelt.

Structure of ribosomal DNA in Physarum polycephalum

Journal of Molecular Biology, 1976
Abstract 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.

Kinetics of Mating inPhysarum Polycephalum

Mycologia, 1979
Plasmodium 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 ...

The development of sporulation competence in Physarum polycephalum

Developmental Biology, 1979
Abstract Plasmodial cells of the slime mold Physarum polycephalum become “competent” for sporulation following a prolonged period of dark starvation in the presence of nicotinamide. Sporulation can then be induced by illumination. Plasmodia are found to release into the medium during starvation one or more cellular products that promote sporulation.

Mutagenesis and mutant selection in Physarum polycephalum

Molecular and General Genetics MGG, 1972
Physarum 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.

DNA replication in Physarum polycephalum

Journal of Molecular Biology, 1972
Abstract 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.

Plasmodial ultrastructure of the myxomycete Physarum polycephalum

Tissue and Cell, 1972
Abstract 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.

Nuclear matrix proteins of Physarum polycephalum

Molecular Biology Reports, 1986
The 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 ...

Characterization of the Thymidine Kinase of Physarum polycephalum

The Journal of Biochemistry, 1983
Thymidine kinase [ATP: thymidine 5'-phosphotransferase, EC 2.7.1.21] has been purified more than 3,500 fold from microplasmodia of Physarum polycephalum. Properties of the enzyme were determined on preparations purified 1,400 fold. Thymidine was transformed to dTMP while a stoichiometric quantity of ATP was transformed to ADP.

Ribosomal DNA in spores of Physarum polycephalum

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1978
DNA was isolated from plasmodia, spores and newly hatched amoebae of the slime mould Physarum polycephalum. The DNA preparations were fractionated in CsCl gradients and each fraction hybridised to combined 19 S + 26 S rRNA. In all three DNA preparations hybridisation was found to be limited to satellite DNA (rho = 1.714 g/cm3) and at saturation was ...
