| synthesis and some properties of an actin-like nuclear protein in the slime mold physarum polycephalum. | a protein was extracted from isolated nuclei of the slime mold physarum polycephalum which could be labeled with radioactive precursors only during g(2) phase. the native protein was purified by extraction in low-ionic-strength buffer [10 mm tris(hydroxymethyl)aminomethane-hydrochloride] of isolated nuclei and by preparative polyacrylamide gel electrophoresis. it was extracted from isolated nucleoli. its electrophoretic properties in three different polyacrylamide gel systems, its molecular weig ... | 1971 | 5166857 |
| nuclear acidic protein changes during differentiation in physarum polycephalum. | a class of acidic nuclear phosphoproteins has been isolated throughout the mitotic cycle and at two points during differentiation in the slime mold physarum polycephalum. the electrophoretic profiles of these proteins are reproducible and unchanging throughout the mitotic cycle, but reproducible changes occur during differentiation. the proteins are rapidly synthesized after mitosis, and their molecular weights range from 34,000 to 88,000. the proteins rapidly incorporate [(32)p]orthophosphate, ... | 1971 | 5167331 |

| interruptions in single strands of the dna in slime mold and other organisms. | the molecular weight of single-stranded dna from the slime mold physarum polycephalum has been determined by alkaline gradient centrifugation. the average molecular weight during dna synthesis ( approximately 1.5 x 10(7) d) is less than that observed in nonsynthetic periods ( approximately 4 x 10(7) d). on the basis of a chromosome number of 50 per nucleus and a dna content of 1 mumug per nucleus, we are led to conclude that at ph 12 each chromosome dissociates into 300 (single-stranded) pieces ... | 1967 | 5340660 |
| replication of nucleolus-associated dna during "g2 phase" in physarum polycephalum. | in the myxomycete, physarum polycephalum, the bulk of nuclear dna replication occurs during a period of a few hours immediately following upon mitosis. during the remainder of the intermitotic period, incorporation of thymidine-(3)h continues at a low rate in the region of the nucleolus (radioautographs). a few nuclei incorporated thymidine-(3)h into the extranucleolar chromatin at a high rate at all times of the intermitotic period. these nuclei were exceptionally large and they frequently cont ... | 1969 | 5387995 |

| induction of spherule formation in physarum polycephalum by polyols. | a method has been developed for inducing spherule formation (spherulation) in the myxomycete physarum polycephalum by transferring the culture to synthetic medium containing 0.5 m mannitol or other polyols. this morphogenetic process occurred within 12 to 35 hr after the inducer was added. the mature spherules existed as distinct morphogenetic units, in contrast to the clusters of spherules formed during starvation. ninety per cent of the spherules germinated by 24 hr in synthetic medium. the ch ... | 1969 | 5389734 |

| high molecular weight phosphorus compound in nucleic acid extracts of the slime mold physarum polycephalum. | orthophosphate labeled with (32)p was added to the growth medium of the plasmodia of physarum polycephalum. the nucleic acid extracts of such plasmodia contained (32)p that was not removed by nuclease, protease, or amylase. this labeled material was shown to be separable from nucleic acids, could be eluted from a methylated albumin-kieselguhr column at 0.5 m nacl, was of high molecular weight, and had several characteristics in common with polyphosphate. a fraction of this polyphosphate-like mat ... | 1969 | 5392534 |
| biosynthesis of ergothioneine and hercynine by fungi and actinomycetales. | unlike other bacteria, aerobic members of the order actinomycetales show a close biochemical relationship to the fungi by their capacity to synthesize hercynine and ergothioneine. the myxomycete physarum polycephalum, possessing the same synthetic ability, also shows this relationship. contrariwise, the unusual position of yeasts as fungi is indicated by the inability of all yeastlike ascomycetes and all except a few false yeasts to synthesize these two betaines. | 1970 | 5432011 |

| actomyosin from physarum polycephalum: electron microscopy of myosin-enriched preparations. | negatively stained slime mold actomyosin examined by electron microscopy consists mainly of actin-like filaments with occasional angular projections. if some of the actin is removed, the myosin-enriched actomyosin appears as continuous arrowhead structures similar to those of vertebrate striated muscle actomyosin. together with other evidence, the findings suggest that cytoplasmic streaming in physarum may involve a contractile process operating at a relatively low myosin-actin ratio. | 1970 | 5529568 |

| adenosine triphosphate and synchronous mitosis in physarum polycephalum. | synchronous mitoses occur in physarum polycephalum in the absence of cell division. nucleoside and nucleotide profiles were prepared from synchronously growing p. polycephalum at intervals throughout the growth cycle. comparison of these profiles demonstrates that the pool of adenosine triphosphate decreases from a high level at prophase to a minimum through mitosis and increases again in the postmitotic period. these events appear to coincide with changes in the pools of adenosine diphosphate a ... | 1968 | 5691835 |

| structural changes in stigmatella aurantiaca during myxospore induction. | suspension cultures of stigmatella aurantiaca (chondromyces aurantiacus) were induced to form myxospores by addition of glycerol to the growing culture. the cells were fixed at various stages during conversion, thin sections were prepared, and changes in fine structure were studied. vegetative cells are quite similar in their ultrastructure to myxococcus xanthus. during transformation into myxospores, three important cytological changes were observed. granules of storage material, probably polys ... | 1969 | 5773035 |
| laser microscope irradiation of physarum polycephalum: dynamic and ultrastructural effects. | streaming plasmodia of physarum polycephalum were irradiated with a microscope-mounted ruby laser and the resulting changes were recorded by cinemicrography or streak photographs. some lesions were processed for electron microscopy. by varying the incident energy, three levels of response were detected. two transient responses, a gelation briefly blocking streams and a more severe gelation with contraction, changed movement patterns but not organelle ultrastructure. at higher energies, a permane ... | 1969 | 5812426 |
| minor components of the dna of physarum polycephalum. cellular location and metabolism. | dna metabolism in the slime mold physarum polycephalum was studied by centrifugation in cscl of lysates of cultures labeled with radioactive thymidine at various times in the cell cycle. during the g(2) (premitotic) phase of the cell cycle, two components of the dna are labeled. one component is lighter (buoyant density 1.686 g/cc) than the mean of the principal dna (1.700 g/cc), and one is heavier (approximately 1.706 g/cc). the labeled light dna was identified chemically by its denaturability, ... | 1969 | 5812473 |
| growth of large plasmodia of the myxomycete physarum polycephalum. | a method has been developed for growing physarum polycephalum plasmodia that are 8 to 10 times larger than those obtained in the petri dish cultures used by nygaard, guttes, and rusch. in the large-scale procedure, plasmodia were grown in metal trays on a membrane supported by filter paper on stainless-steel screen. plasmodia were started from a ring of inoculum to allow inward and outward migration and were incubated on a rocker so that nutrient medium would flow back and forth, wetting the und ... | 1969 | 5813343 |
