The present work is aimed to study the effects of different concentrations of mercuric chloride on the acellular slime mold Physarum polycephalum. The effects of this heavy metal on cytoplasmic shuttle streaming, plasmodial structure, and growth were studied. Mercuric chloride (15-20 μg/ml) induced a direct and irreversible termination of cytoplasmic streaming followed by a contraction of the whole plasmodium, strong blebbing, vacuolization, disintegration and disorganization of plasma membrane. Plasmodial strands of Physarum treated with different concentrations of mercuric chloride showed irregular cytoplasmic streaming, vacuolization of endoplasm, blebbing of plasmalemma, and disorganization of internal structure.
