Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Characterised by their ability to transform from a single-celled organism into an elaborate assemblage of thousands of synchronously-moving cells, Dictyostelids are often referred to as 'social amoebae', and have been the subjects of serious

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.

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.

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

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).

The model organism Dictyostelium discoideum.
Methods in molecular biology, 2013Much of our knowledge of molecular cellular functions is based on studies with a few number of model organisms that were established during the last 50 years. The social amoeba Dictyostelium discoideum is one such model, and has been particularly useful for the study of cell motility, chemotaxis, phagocytosis, endocytic vesicle traffic, cell adhesion ...

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.

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.
