What cells in Dictyostelium discoideum slime mold provide altruism?
What cells in Dictyostelium discoideum slime mold provide altruism?
One model system for microbial cooperation is the cellular slime mold Dictyostelium discoideum [5]. These unicellular amoebae aggregate when starved and form multicellular fruiting bodies in which stress-resistant spores are held aloft by dead stalk cells—a form of microbial altruism.
What is the common name of Dictyostelium?

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.
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 a fungus?
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”.
What is it about the biology of Dictyostelium that makes it a useful model organism for studying Multicellularity?
What is the life cycle of Dictyostelium?
Its unique asexual lifecycle consists of four stages: vegetative, aggregation, migration, and culmination.
Is Dictyostelium discoideum a slime mold?
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.
