Life cycle. Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa.Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime.
Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution. The “acellular” moniker derives from the plasmodial stage of the life cycle : the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a ...
The cellular slime mold was formerly considered to be fungi following their discovery in 1869 by Brefeld. Although they resemble fungi in some respects, they have been included in the kingdom Protista. [4] Individual cells resemble small amoebae in their movement and feeding, and so are referred to as myxamoebae.
Similarly, in Dictyostelium discoideum (slime mold), SDF-2 and cytokinins are secreted during late development to trigger signal transduction pathways that lead to an increase in the activity of the cAMP-dependent protein kinase, PKA, which triggers rapid encapsulation as well as ensuring spore dormancy.
Some are just goofy, such as a slime slingshot, which allows participants to catapult slime at someone else. (Don't worry, they're tucked safely behind plexiglass.) Stations may focus on touch ...
In some classifications, Dictyostelium was placed in Acrasiomycetes, an artificial group of cellular slime molds, which was characterized by the aggregation of individual amoebae into a multicellular fruiting body, making it an important factor that related the acrasids to the dictyostelids.
