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.

Alkaline phosphatase of Physarum polycephalum is insoluble [PDF]

Archives of Microbiology, 2007
The plasmodia of Physarum polycephalum grow as multinucleated cells in the presence of sufficient humidity and nutriment. Under non-illuminating conditions, stresses such as low temperature or high concentrations of salts transform the plasmodia into spherules whereas dehydration induces sclerotization.

Purine metabolism in microplasmodia of Physarum polycephalum

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1979
The uptake and utilization of purine nucleosides and purines in microplasmodia of Physarum polycephalum were investigated. The results revealed a unique pattern, namely that exogenous purine nucleosides are readily taken up and metabolised, while free purine bases are hardly taken up.

Thermotaxis in a slime mold, Physarum polycephalum

Behavioral Biology, 1975
Physarum polycephalum is thermotactic toward 29 ± 1°C avoiding both higher and lower temperatures. 29°C appears to be a- combined optima for growth and locomotion. It is likely that thermotaxis is a more efficient way of avoiding unfavorable temperature than transforming into spherules.

Microplasmodium Dynamics of Physarum Polycephalum

2010
The slime mold Physarum polycephalum exhibits well-known oscillations of its vein network, which drive the so-called shuttle streaming of endoplasmic fluid within the veins. These oscillations are already visible in microplasmodia, which are precursors of extended networks.

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 ...

Galvanotaxis of the Plasmodium of Physarum Polycephalum

2012
The traditional research method of the natural sciences chooses an element paying attention to the various elements in the natural world and analyzing their characteristics and components. To analyze the complicated structure of nature, one normally applies a highly precise device and the sophisticated expertise. This method will exclude other elements

Genetic Analysis in Physarum polycephalum

1986
Detailed knowledge of the life cycle is a prerequisite for meaningful genetic analysis of any organism. The life cycle of Physarum polycephalum as we know it in the laboratory is summarized in Fig. 1-1.

STUDIES ON SCLEROTIZATION IN PHYSARUM POLYCEPHALUM

American Journal of Botany, 1954
THE RESISTANT STRUCTURE produced by gradual desiccation of a myxomycete plasmodium is usually termed a sclerotium. Since this stage does not appear to be necessary for the completion of the life cycle of the Myxomycetes it has received relatively little attention.
