What are Dictyostelium cells?
What are Dictyostelium cells?
Dictyostelium is a genus of single- and multi-celled eukaryotic, phagotrophic bacterivores. Though they are Protista and in no way fungal, they traditionally are known as “slime molds”. The genus Dictyostelium is in the order Dictyosteliida, the so-called cellular slime molds or social amoebae.
Is Dictyostelium discoideum a protozoa?
Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa. Commonly referred to as slime mold, D….
Where are Dictyostelium found?
Dictyostelium often form on fruiting bodies with spores, but are usually found inhabiting soil, animal dung, humus, and other decaying matter. They are usually located in forest habitats, and can be found around the world. Dictyostelium are useful organisms for research.

What is Dictyostelium used for?
Dictyostelium is a powerful model system to study important biomedical problems. Numerous molecular genetics techniques, including gene knock-out, gene knock-in, restriction enzyme-mediated mutagenesis, RNAi, and inducible gene expression, allow a wide range of biological questions to be tested.
Why is Dictyostelium a model organism?
Dictyostelium discoideum is a haploid, eukaryotic amoeba that normally lives a solitary life, but it can be induced to form a multicellular organism. This, together with a unique combination of biochemical, genetic and molecular tools make it a versatile model for cellular and organismic glycobiology.
Is Dictyostelium unicellular or multicellular?
When bacterial food is plentiful, Dictyostelium are single-celled amoebae. However, when the food supply is exhausted, Dictyostelium produce a chemoattractant, which signals to neighboring cells to aggregate into a multicellular organism of ~ 215,000 cells [15, 16].
What types of study is Dictyostelium most used for?
Dictyostelium discoideum is a forest floor-dwelling amoeboid protozoan (slime mould) that serves as a model organism for studying cell biology, differentiation, chemotaxis and cell-cell interaction.
Is Dictyostelium discoideum a slime mold?
DICTYOSTELIUM: THE “SLIME MOLD” Dictyostelium discoideum is a haploid protist that has been intensively studied, primarily because of its social life. A group of free-living cells can aggregate into a motile mass that exhibits morphological and biochemical development for the purpose of common reproduction.
Why is Dictyostelium important?
Dictyostelium discoideum is a cellular slime mold that serves as an important model organism in a variety of fields. Cellular slime molds have an unusual life cycle. They exist as separate amoebae, but after consuming all the bacteria in their area they proceed to stream together to form a multicellular organism.
