Abstract The activities of a number of enzymes have been determined in growing plasmodia of Physarum polycephalum at 1 h intervals during the naturally synchronous nuclear division cycle. The enzymes selected represent the main pathways of energy metabolism, they do not require posttranslational steps for activation, nor are they directly involved in

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 ...

Routing Physarum with repellents
The European Physical Journal E, 2010Plasmodium of Physarum polycephalum is a single cell with many nuclei. Plasmodium is an easy-to-experiment-with biological substrate, a multi-functional bio-material used to implement novel and future computing architectures. The plasmodium exhibits typical features of excitable chemical systems and capable for distributed sensing, parallel information

Novel taxis of the Physarum plasmodium and a taxis-based simulation of Physarum swarm
The 6th International Conference on Soft Computing and Intelligent Systems, and The 13th International Symposium on Advanced Intelligence Systems, 2012The plasmodium of Physarum polycephalum is a unicellular and multinuclear giant amoeba. We investigated the behavior of the plasmodium in magnetic field and found that the organism has magnetotaxis. Based on this new finding, we further studied how the taxis benefit the survival of the plasmodium using a simple swarm model.

Physarum computing and topology optimisation
International Journal of Parallel, Emergent and Distributed Systems, 2016AbstractThe plasmodium stage of the giant single-celled amoeboid organism Physarum polycephalum, or true slime mould, dynamically adapts its body plan in response to environmental stimuli, including nutrient location, temperature gradients, light exposure, and predatory threats.

The mitotic oscillator in Physarum polycephalum
Journal of Theoretical Biology, 1975This article reports evidence that mitosis in the syncytial plasmodium of Physarum polycephalum is controlled by a continuous biochemical oscillation. In the Introduction, inferences drawn from past experiments are evaluated. Results of experiments fusing two plasmodia at most possible phases and phase differences are reported.

Insertional editing in mitochondria of Physarum
Seminars in Cell Biology, 1993RNA produced from a number of genes on the mitochondrial (mt) DNA of Physarum polycephalum have nucleotides inserted at specific sites in their sequence. These insertions are spaced at approximately 25 nucleotide intervals and create open reading frames in mRNA and functional structure in tRNAs and rRNAs.

Acceleration-sensitivity threshold of Physarum
Journal of Biotechnology, 1996Free-living cells show distinct gravisensitivities and often use the gravity ('g') vector for their spatial orientation. The rhythmic contractions of the ameboid Myxomycete (acellular slime mold) Physarum polycephalum are a sensitive parameter which can be modified by external stimuli.

In the following, we attempt to demonstrate that Physarum is an adequate model system for studies of the eukaryotic mitotic cycle, cell differentiation, and motility, A schematic presentation of the life cycle of this organism is shown in Fig. 1-1, at the end of this chapter. (See Sauer and Pierron, 1983, for a recent review).
