Thermotaxis in a slime mold, Physarum polycephalum
Behavioral Biology, 1975Physarum 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.

DNA polymerase δ of Physarum polycephalum
Current Genetics, 1995DNA polymerase delta from the phylogenetically ancient slime mold Physarum polycephalum has been 380-fold enriched from amoebae. It was found to have the properties typical for this type of DNA polymerase from higher eukaryotes with regard to effectors, template-primer acceptance, co-purification with 3'-5'-exonuclease activity, as well as the effect ...

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 ...

Interfacing physarum polycephalum with organic memristors
2015 International Conference on Memristive Systems (MEMRISYS), 2015Since their prediction, memristive devices revolutionized the world of computing and nowadays they have been widely considered as promising candidate for mimicking synapses. In particular, organic-based memristors allow the construction of circuits capable of learning.

The pathway of photosensory transduction in Physarum polycephalum
Cell Biology International Reports, 1981Irradiation of the plasmodia of Physarum with blue and white light results in a transient change of theie oscillatory contraction frequency. This reaction to light decreases with increasing distance from the illuminated area (Block and Wohlfarth-Bottermann, 1981).

Purine metabolism in microplasmodia of Physarum polycephalum
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1979The 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.

Alkaline phosphatase of Physarum polycephalum is insoluble
Archives of Microbiology, 2007The 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.

Studies on microplasmodia of Physarum polycephalum
Cell and Tissue Research, 1991Fragments excised from front regions of thin-spread Physarum plasmodia were used to examine a possible correlation between the periodical dynamic activity of such specimens and the spatial organization of actin ...

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.
