Annual Review of Physiology, 1982
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.

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’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.

Meiosis in Dictyostelium mucoroides
Nature, 1974THE cellular slime moulds are favourable organisms for the study of morphogenetic processes. But so far, genetic analysis of their development has been hampered by the apparent absence of a true sexual cycle, although progress has been made in parasexual genetic analysis1–3.

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 ...

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 ...

Monitoring Autophagy in Dictyostelium
2013Autophagy is an intracellular degradation mechanism essential for cell survival and maintenance of cellular homeostasis, differentiation, and development. Recent research has highlighted the impact of autophagy in neurodegenerative diseases and aging.

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.

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
