Abstract

Brefeldin A (BFA) induces a major aggregation of the Golgi apparatus (GA) in root cells followed by a complete, but reversible, vesiculation of the Golgi stacks which form two or more BFA compartments in the cytosol. This effect is monitored by the immunofluorescence of a Golgi antigen stained with a monoclonal antibody JIM 84, and by transmissionelectron microscopy. Depolymerisation of the microtubule cytoskeletonafter oryzalin or colchicine treatment does not disturb the three dimensional organisation of the GA in control cells and does not affect any BFA induced Golgi stack movements. After disruption of the actin cytoskeleton with cytochalasin D many aggregates of Golgi stacks can be observed in root cells and these are sensitive to BFA treatment, forming multiple BFA compartments. N-ethyl-maleimide has no effect on the organisation of the GA in control roots but totally inhibits the actionof BFA. Thus, it appears that spatial organisation of the GA and the BFA induced Golgi stack movements are actin dependent whilst BFA induced vesiculation of the GA is a structurally separate event.
