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 … See more In the wild, D. discoideum can be found in soil and moist leaf litter. Its primary diet consists of bacteria, such as Escherichia coli, found in the soil and decaying organic matter. Uninucleate amoebae of D. discoideum … See more The life cycle of D. discoideum begins when spores are released from a mature sorocarp (fruiting body). Myxamoebae hatch from the spores under warm and moist conditions. During their vegetative stage, the myxamoebae divide by mitosis as they feed on … See more Because many of its genes are homologous to human genes, yet its lifecycle is simple, D. discoideum is commonly used as a See more Sentinel cells in Dictyostelium discoideum are phagocytic cells responsible for removing toxic material from the slug stage of the social cycle.
