[Letter: Effect of a reversible increase in plasma membrane permeability of plant root cells during deplasmolysis]

The studied effect of a reversible increase of permeability of plasmic membranes of plant root cells does not depend on chemical nature of plasmolys-inducing agents. This effect is conditioned by the process of deplasmolysis itself. It is suggested that the process of reversible depolimerization of the protein component similar to F-action and located in the membrane polar regions.
