Abstract The influence of cytochalasin B (CB), a potent inhibitor of cytoplasmic streaming, on 86Rb-labelled K+ translocation by detopped Lycopersicon esculentum Mill., Cucumis sativus L. and Zea mays L. plants was examined by measuring the radioactivity in xylem exudate before and after the addition of CB to the medium bathing the roots. CB caused complete cessation of cytoplasmic streaming in root segments within 15 min but was without effect on either total 86Rb uptake or exudation. Thus factors other than cytoplasmic streaming limit the movement of K+ across the symplast of the root of higher plants.
