Mutants in Phototaxis of Dictyostelium discoideum
Nature, 1970ONE of the more interesting behavioural characteristics of the cellular slime mould, Dictyostelium discoideum, involves the concerted migration of thousands of amoebae in a pseudoplasmodium or slug towards light. There have been several studies of the phenomenon, and the action spectrum for phototaxis has been shown1–4 to have peaks at 425 and 550 nm ...

Pacemaker mutants of Dictyostelium discoideum
Developmental Biology, 1974Abstract In this paper, I report measurements of the time intervals between aggregation waves in two morphogenetic mutants of Dictyostelium discoideum NC-4. The mutants both have abnormal wave periodicity and their abnormalities are interpreted in terms of defects in the cellular properties which underlie wave propagation.

Modelling Dictyostelium discoideum Morphogenesis: the Culmination
Bulletin of Mathematical Biology, 2002The culmination of the morphogenesis of the cellular slime mould Dictyostelium discoideum involves complex cell movements which transform a mound of cells into a globule of spores on a slender stalk. We show that cyclic AMP signalling and differential adhesion, combined with cell differentiation and slime production, are sufficient to produce the ...

Rho Signaling in Dictyostelium discoideum
2016Small GTPases of the Rho family are ubiquitous molecular switches involved in the regulation of most actin cytoskeleton dependent processes and many other processes not directly linked to actin. D. discoideum is a well-established model organism for studies of the actin cytoskeleton and its regulation by signal transduction pathways. D.

The Model Organism Dictyostelium discoideum
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 ...

The Inositolcycle of Dictyostelium Discoideum
1990Transmembrane signal transduction is characterized largely by the interaction between its components: ligand, receptor on the surface of cells, G-protein subunits at the inner face of the plasma membrane, and effector enzymes. The effector enzymes may vary widely depending on the organism and the ligand, and include adenylate cyclase, guanylate cyclase,
