Control of cellular differentiation by temperature in the cellular slime mould Dictyostelium discoideum.
The effects of low temperature on morphogenesis and cellular differentiation of Dictyostelium discoideum were examined. During incubation at 5 degrees C, the vegetative and preaggregation cells never developed, but cell masses at the aggregation or slug stage developed to form hemispherical, or dumbbell-shaped multicellular structures. By staining with FITC-antispore IgG, the structures formed ...

متن کاملMotive force of the migrating pseudoplasmodium of the cellular slime mould Dictyostelium discoideum.
Motive forces of migrating pseudoplasmodia (slugs) of Dictyostelium discoideum were determined by application of a double-chamber method. The motive force of a whole slug was proportional to its volume, the value per unit volume being 5.85 x 10(-6) dyne/cm3 (58.5 N cm-3). The motive force was independent of temperature (13.5--26 degrees C) and decreased during prolonged migration. Motive force ...
متن کاملCell density dependence of the aggregation characteristics of the cellular slime mould Dictyostelium discoideum.
We have measured fruiting body density and spore formation efficiency in Dictyostelium discoideum as functions of initial cell density. Experiments were performed on agar made up with distilled water and on buffered agar. Minor differences are seen; these are discussed. The functions show 4 regions of density dependence which can be accounted for by changes in aggregation characteristics with d...
متن کاملThe isolation and subfractionation of plasma membrane from the cellular slime mould Dictyostelium discoideum.
A procedure for the isolation and separation of three different subfractions of plasma membrane from the cellular slime mould Dictyostelium discoideum is described. The cells were disrupted by freeze-thawing in liquid N(2) and plasma membranes were purified by equilibrium centrifugation in a sucrose gradient. The cell surface was labelled with radioactive iodide by using the lactoperoxidase iod...
