Abstract
The multinuclear plasmodia of acellular slime molds can reach a size of several m2 and are able to migrate with a velocity of up to 1 cm hr−1. The basis of this rapid locomotion is a permanent translocation of cytoplasm plus nuclei in the form of a shuttle streaming: the endoplasm flows back and forth with a periodicity of ½ to 2 min, especially visible in plasmodial strands which characterize the rear part of a plasmodium. The frontal part of a plasmodium consists of a more or less continuous protoplasmic sheet which also encloses the pathways of an endoplasmic shuttle streaming. This migration polarity of a plasmodium is subject to changes due to, e.g., chemical stimuli.
