Mitochondrial RNAs in the acellular slime mold Physarum polycephalum contain nucleotides that are not encoded in the mitochondrial genes from which they are transcribed. These site-specific changes are quite extensive, comprising ~4% of the residues within mRNAs and ~2% of rRNAs and tRNAs. These "extra" nucleotides are added co-transcriptionally, but the means by which this is accomplished have...

Carbon nanotubes (CNTs) offer attractive opportunities due to their physical, electrical, mechanical, optical, and thermal properties. They are used in a wide range of applications found numerous consumer products. On the downside, increasing presence environment poses potential threats living organisms ecosystems. The aim this study was evaluate toxicity double-walled carbon (DWCNTs) on new mo...

We have previously observed the apparent displacement of microfilaments over microtubules in the backbone structure of permeabilized flagellates of Physarum polycephalum upon addition of ATP (Uyeda, T. Q. E , and M. Furuya. 1987. Protoplasma.

We implement Kolmogorov-Uspensky machine on a plasmodium of true slime mold {\em Physarum polycephalum}. We provide experimental findings on realization of the machine instructions, illustrate basic operations, and elements of programming.

During two years of passage, several myxamoebal strains of Physarum polycephalum changed with regard to their properties in crosses and plaque morphology. These changes have been correlated with increased nuclear deoxyribonucleic acid content.

the genus tanacetum is one of the most important medicinal plants that contains 26 species in iran, 12 of them are endemic. this paper reports the essential oil composition of  tanacetum angulatum willd. tanacetum canacens dc. and tanacetum pinnatum boiss. growing wild in iran. plant flowers and leaves were collected from different locations of north- west of iran. samples were hydro-distilled ...

The Physarum Polycephalum, or true slime mold, is a large multi-nuclear cell which uses a network of tube-like structures called pseudopodia to connect food sources and ensure its survival. Much study has been done on the behavior and formation of the pseudopodia, with a special focus on the tendency to choose an efficient path between the food sources [1, 2, 4, 6, 9, 10, 12, 13]. When food is ...

Biological systems that have been subjected to vast time periods of evolution, have provided numerous times inspiration for problem solving techniques. These systems have evolved to survive in harsh environments, thus they provide more efficient solutions than the conventional methods. The inspiration of this study was based on the computing abilities that Physarum Polycephalum performs on grap...

Purified antibodies from an antiserum against S-phase proteins of the myxomycete Physarum polycephalum were attached to protein-A-Sepharose CL-4B. A late G2-phase extract that contained a mitosis-stimulating protein was applied to this immunoadsorbent, and the mitosis-stimulating protein was enriched by a factor of ten. This protein, which is present in the cell in low amounts, is synthesized i...

Physarumpolycephalum is an acellular slime mould whose histones are of general interest because they allow comparisons to be made between lower eukaryote and higher eukaryote histones and, perhaps more importantly, they provide a unique opportunity for the study of histone changes in the mitotic cycle, which is naturally synchronous in P. polycephalum plasmodia, and during differentiation. Stud...
