Electroporation of Physarum polycephalum
2003The protist Physarum polycephalum is a convenient system for studies of molecular and cellular biology of fundamental eukaryotic processes, including DNA replication, mitotic regulation, single-cell development, the cytoskeleton, and motility. The life cycle of this acellular slime mold exhibits a variety of developmental transitions, and the two ...

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 development of sporulation competence in Physarum polycephalum
Developmental Biology, 1979Abstract 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, 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 ...

DNA polymerase ? 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 ...

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.

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.

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).
