Hydrodynamics of cytoplasmic streaming and the cytoskeletal tubulin component in cells of Elodea densa internodes

A spin-echo NMR method was applied to study hydrodynamic parameters of cytoplasmic streaming and to examine translational diffusion of cytoplasmic water in stems of elodea (Elodea densa (Planch.)

The action of vinblastine was manifested in a monotonic decrease of the translational diffusion. After 24-h treatments with colchicine and vinblastine, the translational diffusion was slowed down.

Abstract

A spin-echo NMR method was applied to study hydrodynamic parameters of cytoplasmic streaming and to examine translational diffusion of cytoplasmic water in stems of elodea (Elodea densa (Planch.) Casp.) treated with antimitotic drugs. Within the first few hours after colchicine treatment, the dynamics of translational displacement followed the curve with a transient maximum. The action of vinblastine was manifested in a monotonic decrease of the translational diffusion. After 24-h treatments with colchicine and vinblastine, the translational diffusion was slowed down. All these changes induced by antimitotic drugs were observed on the background of unaltered rate of cytoplasmic streaming.
