Motility Patterns and Structure Formation Dynamics of Physarum Polycephalum — •Christina Oettmeier, Siddharth Deshpande, and Hans-Günther Döbereiner — Institut für Biophysik, Universität Bremen

The plasmodium of the slime mold Physarum Polycephalum is a unicellular organism with a large number of nuclei, which can grow several square centimeters in area. The plasmodium develops veins, which cause reversible shuttle streaming of the endoplasm via periodic contractions. We report on the dynamics of this network during formation, growths, and plasmodium extension as a function of environmental conditions. Especially, we are interested in the role of endoplasmic streaming in network formation.
