Dictyostelium, the Social Amoeba

Research output: Chapter in Book/Report/Conference proceeding › Chapter › peer-review

Abstract

The Dictyostelia present a splendid opportunity for studies of sociality and genetic conflicts of interest. These eukaryotic amoebae aggregate upon starvation to form a multicellular individual in which some formerly independent individuals die to form a stalk that lifts the others to a better place for sporulation and dispersal. Dictyostelia vary in their social organization and can be cultured from soil samples in nearly all parts of the world. Genome sequences are available for increasing numbers of species; many molecular pathways are known; experimental evolution is feasible. Who lives, who dies, and how sociality is structured are great questions that are easily addressed in this group.
