説明
The effects of cytochalasin B (CB) and lead acetate, inhibitors of "primary streaming" in Characean cells, were examined on "secondary streaming" in Vallisneria mesophyll cells with reference to the cessation of streaming and the reversal of its direction.<BR>Cytoplasmic streaming was reversibly inhibited by CB in the concentration range of 10-100 μg/ml. The ratio of cells showing newly established streaming in the reverse direction after removal of CB to the total number of cells observed before treatment increased depending on the concentration and the duration of treatment, reaching 50 % after 24 h for CB treatment at 10-100 μg/ml. Lead acetate at 50-100 mM caused the complete cessation of streaming, but the streaming gradually recovered after its removal; however, lead acetate did not induce a change in the streaming direction. Properties of the motile apparatus in secondary streaming are discussed on this basis.
