Phosphoproteins in dictyostelium discoideum
Journal of Supramolecular Structure and Cellular Biochemistry, 1981AbstractThe phosphoproteins of Dictyostelium discoideum were compared at different stages of development by polyacrylamide gel electrophoresis. Certain phosphoproteins of vegetative amoebae were conserved while others appeared and disappeared during development.

Dictyostelium discoideum exists as single amoeboid cells during the first phase of its developmental cycle. These cells phagocytose bacteria. Chemo taxis to compounds released from the bacteria (e.g. folic acid) is probably involved in food seeking (95).

Current Opinion in Genetics & Development, 2004
During starvation-induced Dictyostelium development, up to several hundred thousand amoeboid cells aggregate, differentiate and form a fruiting body. The chemotactic movement of the cells is guided by the rising phase of the outward propagating cAMP waves and results in directed periodic movement towards the aggregation centre.

The cytochromes of Dictyostelium discoideum
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19831. Low temperature (77 K), reduced oxidized difference spectra of "purified" mitochondria of Dictyostelium discoideum revealed the presence of b, c and a-type cytochromes. 2. The same components were also identifiable in intact organisms, the only possible discrepancies from the contribution by "microsomal" b-type cytochromes which showed major maxima ...

Dictyostelium’s pisatin response
Journal of Biosciences, 2022Dictyostelium discoideum is a species of free-living soil amoeba that feeds on bacteria that grow on decaying vegetation. Though the present account deals with D. discoideum, I use the more colloquial 'dictyostelium' in this article. In 1989, as a new PI, I began to study the response of D. discoideum amoebae to pisatin.

Dictyostelium slugs are able to respond to environmental stimuli in an extremely sensitive and efficient way. This enables a slug to migrate to more favourable locations for formation of fruiting bodies and dispersal of spores. Phototaxis is a readily assayed phenotype and reflects the interactions of environmental stimuli with morphogenetic signalling

Nuclear Plasmids of Dictyostelium
1999Decades of studying plasmids in bacterial systems have led to their characterization as autonomously replicating, extrachromosomal DNA molecules carrying no elements essential to the viability of the organism. The information obtained through the examination of bacterial plasmids provided the foundation on which much of the progress in genetic ...

The search for morphogenes in Dictyostelium
BioEssays, 1988AbstractClassical embryological studies have led to the suggestion that cells in developing tissues may be directed to differentiate along a particular pathway by the concentrations of molecules called morphogens. Studies of the slime mould Dictyostelium discoideum, which has a simple tissue pattern consisting of only two cell types, have revealed ...

Multicellular Development of Dictyostelium
Cold Spring Harbor Protocols, 2008INTRODUCTIONDictyostelium discoideum is a unicellular eukaryote often referred to as a “social ameba” because it can form a multicellular structure when nutrients are depleted from the immediate environment of the cells. In the laboratory, this is accomplished simply by replacing the growth medium with a buffer solution.

Differentiation and patterning in Dictyostelium
Current Opinion in Genetics & Development, 1994Dictyostelium development is orchestrated by diffusible signals. Progress has been made in understanding how cAMP signaling triggers post-aggregative development and in defining the number of cell types that eventually differentiate. Ammonia is an unusual signal that may act by alkalinizing acidic vesicles.
