title: Cell size in Dictyostelium.
abstract: Cellular slime mold amoebae have become a model system for the study of cell motility and the cytoskeleton. A basic problem which all cells face that involves the cytoskeleton is how to control their size. The varied ways in which cellular slime mold amoebae change their cell size--by changing the size at which division occurs, by cell fusion, and by control over cytokinesis--are reviewed. A model is presented which attempts to explain how the mechanisms affected in certain cytokinesis mutants in Dictyostelium discoideum known as phg mutants could be involved in control of cell size in the predatory slime mold Dictyostelium caveatum.
