abstract：:Actin filament (AF) organization was studied during the plasmolytic cycle in leaf cells of Chlorophyton comosum Thunb. In most cells the hyperosmotic treatment induced convex or concave plasmolysis and intense reorganization of the AF cytoskeleton. Thin cortical AFs disappeared and numerous cortical, subcortical and e...
