Effect of Cadmium Chloride (CdCl2) on Cytoplasmic Shuttle Streaming, Structure, Growth and Migration of the Plasmodial Slime Mold Physarum polycephalum

The effect of different concentrations of cadmium chloride on cytoplasmic shuttle streaming, growth, structure and migration of plasmodial strand of Physarum was investigated. Concentrations 25.0 mM CdCl2 induced direct and rapid stop of cytoplasmic streaming followed by complete fixation of the treated plasmodia (neither growth nor migration occurred on nutrient agar plates).
